Which of the following nutrient provide more energy? a. Protein b. Carbohydrate c. Lipids d. Vitamins
Answers
The nutrient which provide more energy is C. Lipids
Among the given options, lipids provide the most energy per unit mass. Lipids, also known as fats, are a concentrated source of energy in the diet. When metabolized, lipids yield approximately 9 kilocalories (kcal) of energy per gram.
Carbohydrates, including sugars and starches, provide approximately 4 kcal of energy per gram. They are a readily available source of energy for the body, particularly for short-term energy needs. Proteins also provide approximately 4 kcal of energy per gram. However, their primary role is not as an energy source but rather as the building blocks for tissues, enzymes, and other important molecules in the body.
Vitamins, on the other hand, do not provide significant energy. They are essential for various biochemical processes in the body but do not contribute directly to energy production.
It is important to note that while lipids provide the most energy per gram, the overall balance and variety of nutrients in a diet are crucial for maintaining optimal health. Nutrient needs vary based on individual factors, such as age, sex, activity level, and overall health goals. Therefore, Option C is correct.

Explain the limitation binomial nominclature (15 marks)
Answers
Answer:
- Binomial nomenclature is a widely accepted naming system, which is used in the naming of living things. Multiple native names make it extraordinarily tough to establish an organism globally and maintain an observation of the variety of species. Thus, it creates quite a lot of confusion. To eliminate this confusion, a normal protocol came up. According to it, every organism would have one scientific title which might be utilized by everybody to establish an organism.
What is binomial nomenclature?
Binomial Nomenclature follows a universally accepted naming system, which is used to provide a scientific name to a known organism.
Binomial Nomenclature also known as the binary nomenclature.
It uses two-terms during the nomenclature of a specie (plants, animals, and living organisms) that is why it called two-term naming system.
The scientific name of an organism or binomial nomenclature consists of two words, such as the generic epithet and describes the genus and the specific epithet and refers to the species of the organism.
Both of this term is written in italic and the genus name is capitalized.
Binomial nomenclature was given by Swedish botanist and physician Carl Linnaeus. He also called the founder of modern taxonomy.
Carl Linnaeus described and classified thousands of species of plants and animals in his book Systema Naturae.In this technique, there are particular guidelines that are followed while naming organisms. This normal algorithm is relevant to plants and animals whereas giving them distinctive names inside a given system.There are two worldwide codes such as the International Code of Botanical Nomenclature (ICBN) deal with the biological nomenclature for plants and the International Code of Zoological Nomenclature (ICZN) deal with the biological nomenclature of animals.
These two codes agreed upon by all of the biologists over the world for the naming protocol. These codes ensure that every organism will get a selected identity and that identity is globally recognized.
Summary of the limitation binomial nominclature:
- Some of the main drawbacks of binomial nomenclature are: If two or more names are actually in use in compliance with the priority rule, the appropriate name will be used first and the other names will end up being synonyms because authenticity is synonymous with the senior.

Even in cases of simple Mendelian inheritance within a population, the ratio of phenotypes of a specific character is rarely the same as the ratio of alleles for that character. Explain why these ratios differ.
Answers
Answer:
Even though the ratio of alleles for a specific character in a population is usually the same, the ratio of phenotypes of that character can differ due to the presence of multiple alleles of the same gene, dominance and recessiveness, and epistasis. In the case of multiple alleles, different alleles of the same gene can result in different phenotypes, so the ratio of phenotypes may not be the same as the ratio of alleles. Additionally, dominance and recessiveness can cause different alleles to result in the same phenotype, meaning the ratio of phenotypes may be different from the ratio of alleles. Finally, epistasis occurs when one gene affects the expression of another, which can also cause the ratio of phenotypes to differ from the ratio of alleles.

1. padding at a full speed is putting new demands on a Joe's body. what are these new demands and how does the body respond to them?
2. what changes in Joe's muscles promote unloading of oxygen from hemoglobin for use by the muscle cells when paddling?
3. what conflict is produced between Joe's need to keep his body cool and his need to remove his nitrogenous waste from his blood? what did he do before the race to help alleviate this conflict?
4. Joe stopped paddling and his muscles are at rest. why are his heart and breathing rates still so high?
5. why is he sweating more after the race than during the race?
6. what changes have occurred in his blood chemistry since the start of the race?
Answers
Answer:
1. When paddling at full speed, Joe's body demands an increased supply of oxygen to fuel the working muscles. The body responds by increasing the heart rate and breathing rate to deliver more oxygen to the muscles. The body also needs to regulate its temperature, which increases as a result of the energy expended during paddling. This puts a demand on the body to cool down through sweating and increased blood flow to the skin.
2. During paddling, Joe's muscles undergo changes that promote unloading of oxygen from hemoglobin for use by the muscle cells. These changes include an increase in temperature, acidity, and levels of carbon dioxide. These changes cause hemoglobin to release oxygen more readily, allowing the working muscles to extract more oxygen from the blood.
3. Joe's need to keep his body cool conflicts with his need to remove his nitrogenous waste from his blood. Nitrogenous waste, such as urea, is produced by the breakdown of proteins in the muscles and needs to be removed from the blood by the kidneys. Sweating helps to cool the body down but also removes water from the body, which can make it harder for the kidneys to filter nitrogenous waste. Before the race, Joe may have increased his water intake to help alleviate this conflict and ensure proper kidney function.
4. Even when Joe's muscles are at rest, his heart and breathing rates remain high because his body is still working to recover from the intense exercise. The increased heart rate helps to deliver oxygen and nutrients to the muscles, while the increased breathing rate helps to remove carbon dioxide and other waste products from the body.
5. Joe is sweating more after the race than during the race because his body is still trying to cool down and regulate its temperature. The increased sweating helps to remove excess heat from the body, which was generated during the intense exercise.
6. Several changes have occurred in Joe's blood chemistry since the start of the race. These include an increase in levels of lactate and carbon dioxide, which are waste products produced by the muscles during intense exercise. There may also be a decrease in pH levels due to the build-up of acid in the blood. Additionally, Joe's blood glucose levels may have decreased as a result of the energy used during the race.
Explanation:
2. Changes in Joe's muscles promote unloading of oxygen from hemoglobin for use by the muscle cells when paddling. These changes include a decrease in pH due to the production of lactic acid, which causes hemoglobin to release oxygen more readily. Additionally, the increase in temperature of the muscle tissue also promotes the unloading of oxygen from hemoglobin.
3. Joe's need to keep his body cool conflicts with his need to remove his nitrogenous waste from his blood. To help alleviate this conflict before the race, Joe likely hydrated himself and wore lightweight, breathable clothing to help regulate his body temperature. During the race, Joe may have also used a cooling towel or other methods to help keep his body cool.
4. Joe's heart and breathing rates are still high after stopping paddling because his body is still working to remove waste products such as lactic acid from his muscles. Additionally, the body is still working to restore oxygen levels to normal and to remove excess heat generated by the muscles during the exercise.
5. Joe is sweating more after the race than during the race because his body is still working to remove excess heat generated by the muscles during the exercise. Additionally, the body continues to produce sweat after exercise to help regulate body temperature and remove waste products.
6. Several changes have occurred in Joe's blood chemistry since the start of the race, including a decrease in pH due to the production of lactic acid, an increase in carbon dioxide due to increased respiration, and a decrease in oxygen levels due to increased use by the muscles. Additionally, Joe's body may be producing more red blood cells to help transport oxygen to the muscles more efficiently.

g When an oxygen molecule diffuses from the air in the lung into the plasma in a capillary in the lung, how many times does it have to diffuse through a plasma membrane before reaching the plasma
Answers
Answer:
The answer is 2.
Explanation:
When oxygen gets into the lungs, it first needs to diffuse through the alveoli and into the blood. Then through the veins and capillaries, it diffuses into all the calls in the body. It does so quite easily because it is a nonpolar and a very small molecule with a low concentration inside the cell. This gives it the ability to diffuse easily through the cell membrane.
So the number of times that oxygen has to diffuse through a plasma membrane is two.

b. How many Calories does she have stored as glycogen?
c. If this same number of Calories were stored as fat, how much would it weigh?
d. Given your answers to a. and c., why do you think your body stores most of its extra energy as fat rather than glycogen?
e. Jordan will be competing in a marathon (26.2 miles). Given her above glycogen stores and the rate at which she consumes them running at marathon pace, she only has enough glycogen to last for 24 miles. What must she do in order to be able to run at the same pace beyond this?
Answers
Considering a well-trained 130-pound female marathon runner named Jordan.
The grams of glycogen Jordan is storing in her body is 884 grams.
Given that:
weight of the female marathon runner = 130 poundsmass of the glycogen = 6.8 grams / pounda.
The total mass of glycogen that Jordan is storing in the body of 130 pounds is:
= 130 pounds × 6.8 grams/pound= 884 gramsb. The amount of Calories she has stored in the body of 130 pounds is calculated as follows.
Since 1 gram is equivalent to 7.716179 kcal
∴
884 grams will be = (884 grams × 7.716179 kcal)/ 1 gram= 6821.102 kcal.c.
Fat is a class of food that the when consumed provides energy to the body. It is usually stored as fatty acid and is measured in pounds.
One pound of fat usually requires an energy of about 3500 calories to burn.
Since 1 pound of fat requires 3500 calories;The weight of the glycogen in fat will be:
= (6821.102 kcal × 1 pound of fat)/3500 kcal= 1.949 pounds of fatd.
The body stores most of its extra energy as fat rather than glycogen because the body after 8 hours of eating, body starvation starts to occur. At this stage, the stored fat is designated to supply energy to the body.
e.
Given that:
Jordan will be competing in a marathon of = 26.2 milesFrom her condition, she has enough glycogen to last for 24 miles.In order for her to be able to run at the same pace beyond the 24 miles, she needs to consume fatty food substances that can help her store additional fat that can be used to provide energy during the marathon race.

E.Some agents are utilized as both an antiseptic and a disinfectant.
Answers
C. Most chemical agents can achieve sterility. The most often utilized antimicrobial substances are ethanol, n-propanol, and isopropyl alcohol. Although it is a chemical, methanol is rarely employed to kill microorganisms because it is so deadly.
Several bacteria, including Escherichia coli, Salmonella, and Staphylococcus aureus,these microorganisms can have their growth slowed by alcohols. Antiseptics, which are applied to living tissue and help prevent infection during surgery, disinfectants (non-selective agents, such as bleach), and antibiotics are the three main categories of antimicrobial agents. Disinfectants kill a wide variety of microbes on non-living surfaces to prevent the spread of illness (which destroy microorganisms within the body). The term "antibiotic," which once only applied to preparations made from living bacteria, is now also used to denote synthetic substances like sulfonamides and fluoroquinolones. Although the term was once only used to refer to antibacterials (and is frequently used as a synonym for them by medical experts and in medical publications), its usage has since expanded to refer to all antimicrobials. Bacteriostatic agents, which inhibit or stop bacterial growth, and bactericidal agents, which kill bacteria, are two other categories of antibacterial agents. Further developments in antimicrobial technologies have led to systems that can do more than only prevent bacteria growth in response. Instead, some forms of porous medium have been created that can kill microorganisms immediately upon contact.

vPoint Source - a source of water discharged to surface water through a discrete point - generally through a pipe, ditch, or channel.
Nonpoint Source - Nonpoint sources, such as parking lots or athletic fields, discharge runoff water to groundwater or surface water; runoff does not come from a pipe, ditch, or channel. These sources may contain pollutants such as pesticides, motor oil, and soaps.
Navigable Waters of the United States For the purposes of the Clean Water Act, the term "navigable waters" includes:
all waters used in commerce, including groundwater;
all interstate waters including wetlands, mudflats, and sand-flats; and
all other waters such as lakes, rivers, streams, wetlands and sloughs.
EPA policy states, "The majority of facilities in the U.S. have the potential to discharge to navigable waters." The Supreme Court decision in (2006) requires the Army Corps of Engineers and the EPA to determine whether there is a "significant nexus" between a navigable waterway and an area a spill might affect. In June of 2007, EPA and the Army Corps of Engineers released provisional interpretive guidance regarding the "significant nexus” question. According to this guidance, the agencies will assert jurisdiction over traditional navigable waters, wetlands adjacent thereto, and relatively permanent tributaries thereof. The agencies will generally not assert jurisdiction over swales and ditches that lack routine water flow. Finally, the agencies will apply the "significant nexus" requirement and make a case-by-case, fact-specific analysis on impermanent tributaries and other wetlands.
Additional executive orders were issued 2015 in 2019. Under the 2019 proposal, traditional navigable waters, tributaries to those waters, certain ditches, certain lakes and ponds, impoundments of jurisdictional waters, and wetlands adjacent to jurisdictional waters would be federally regulated. It also details what are not "waters of the United States," such as features that only contain water during or in response to rainfall (e.g., ephemeral features); groundwater; many ditches, including most roadside or farm ditches; prior converted cropland; stormwater control features; and waste treatment systems.
Could the requirement for one or more NPDES Discharge Permit apply to my campus?
If your campus discharges pollutants directly to navigable waters of the United States through a point source, you must obtain an NPDES permit or redirect the flow of the waste.
Stormwater releases from certain activities require an NPDES permit. The most common activities on college campuses requiring NPDES permits for stormwater are construction activities disturbing more than 1 acre, hazardous waste storage areas operating under the Resource Conservation and Recovery Act permit system, steam-generating power plants, and airports. See Stormwater section below.
Regulations issued by local water authorities, or Publicly Owned Treatment Works (POTWs), not NPDES permits, govern discharges into sanitary sewer systems. See Sewer Use (POTW) section below for more information about requirements for using POTWs for commercial or industrial waste disposal.
What do I have to do related to NPDES Discharge Permits?
Determine where wastewater flows from buildings and processes on your campus. Any industrial or commercial operation (e.g., ice rink melt pits, floor drains, and vehicle wash stations) that discharge into a water of the United States may require an NPDES permit. If required, you must obtain such a permit from the appropriate regulatory agency, probably your state environmental agency.
French drains, dry wells, and septic system leach fields are different from point source discharges because they do not immediately affect surface water. Some state and federal environmental agencies manage these systems under the Underground Injection Control program, part of the Safe Drinking Water Act. See Safe Drinking Water Act for more information.
Details of NPDES
