Answer:
A protein-coding gene has an open reading frame (ORF) that make easier its identification
Explanation:
During translation, the messenger RNA (mRNA) is read by the ribosomes as triplets of nucleotides called codons in the open reading frame (ORF). An ORF can be defined as a gene fragment composed of codons which are translated into amino acids in a polypeptide chain. According to the genetic code, the information encoded by these codons will specify the sequence of amino acids in the protein, as well as the start codon and stop codons of the protein-coding genes. A start codon (AUG) is a site at which translation into protein begins, while stop codons (UAA, UAG, and UGA) mark the site at which translation ends. Moreover, non-coding RNAs (ncRNAs) don't have ORFs because they do not encode for proteins, and therefore their identification is more difficult.
Lab Intro - The Metric System
Exercise A - Measurement or distance
Someone help please
The metric system is a system of measurement that is utilized throughout the world. The fundamental units of the metric system are meter, gram, and liter. In this system, prefixes are used to represent measurements that are bigger or smaller than the fundamental units.
The prefix “kilo-,” for example, indicates a measurement that is a thousand times bigger than the fundamental unit. Lab Intro - The Metric System Exercise A - Measurement or Distance The metric system is used to measure length or distance.
The standard unit of length in the metric system is the meter, which is represented by the symbol “m.” The metric system is used to measure distances or lengths that vary from millimeters (mm) to kilometers (km).In order to determine measurements in the metric system, the fundamental units are combined with prefixes.
For example, one centimeter (cm) is equal to 1/100th of a meter, while one millimeter (mm) is equal to 1/1000th of a meter. One kilometer (km), on the other hand, is equal to a thousand meters (m).

The purpose of the lab is to identify the structures of the digestive and circulatory systems in a rat.
How to explain the informationThe digestive system of a rat is similar to that of other mammals. It consists of the mouth, esophagus, stomach, small intestine, large intestine, and rectum. The mouth is where food is chewed and mixed with saliva.
The esophagus is a muscular tube that carries food from the mouth to the stomach. The stomach is a muscular sac that churns food and mixes it with gastric juices. The small intestine is a long, coiled tube that absorbs nutrients from food. The large intestine absorbs water from food and stores waste products. The rectum is a muscular tube that carries waste products from the large intestine to the anus.
The gallbladder is absent in rats because they have a different diet than other mammals. Rats eat mostly plant matter, which does not require as much bile for digestion as a diet that is high in protein. Bile is a fluid that is produced by the liver and stored in the gallbladder. It helps to break down fats in food.

Describe the aetiology and pathogenesis of type I of diabetes your client has and compare them to either of the other two types of diabetes (Type II or gestational diabetes )
Diabetes mellitus (DM) is a syndrome of etiology, which is the result of the inability of insulin and/or lack of insulin to properly exercise its purposes. It is characterized by hyperglycemia with disturbances in the metabolism of carbohydrates, lipids and proteins. The difference between type 1 diabetes and type 2 diabetes lies in the fact that, in the first case, there is a reduction or lack of insulin production; in the second, the organism develops resistance to the action of this hormone. Diabetes mellitus is a disease characterized by an increase in blood glucose levels.
What is type 1 diabetes?Type 1 diabetes mellitus, like type 2, is characterized by excess glucose (sugar) in the blood, which triggers a series of complications in the body. But, in this case, the disease usually appears in childhood and adolescence, brings symptoms such as the urge to urinate and weight loss, and has an autoimmune origin.
What is the type of type 2 diabetes?Type 2 diabetes is characterized by insufficient production of insulin by the pancreas, or the body's inability to use the insulin produced efficiently. It is more common in people over 40, overweight, sedentary, without healthy eating habits.

g What are the three basic assumptions of Darwinian evolution? Group of answer choices Presence of phenotypic variation, some phenotypic variation due to genetic variation, the given trait has an impact on fitness Presence of phenotypic variation, environmental variation, the given trait has no impact on fitness Presence of phenotypic variation, environmental heritability, the given trait has an impact on fitness Presence of phenotypic variation, trait present in only the mitochondrial DNA, the given trait has an impact on fitness
Answer:
1- Presence of phenotypic variation
2- some phenotypic variation due to genetic variation
3- the given trait has an impact on fitness
Explanation:
The evolutionary theory by natural selection proposed by Darwin in his publication “On the origin of species” (1859) is based on a series of assumptions that enable to understand the amazing biodiversity on the Earth. First, individuals are not identical among them, i.e., there exists variation in the traits among the members of a given population, species, etc. Second, phenotypic variation leads to differential survival and reproduction of the organisms that are best fitted to the environment (i.e., competence among the members of the population). Finally, phenotypic traits are passed from generation to generation (i.e., phenotypic variation is inheritable), thereby favoring offspring from parents more adapted to the environment.
Be able to explain what component of a buffer system is reacting when a strong acid is added. does H2CO3 or NaOH3 react when a strong acid is added?
A buffer system is a solution that can resist changes in pH when small amounts of acid or base are added to it. Buffer systems are composed of two components: a weak acid and its conjugate base (or a weak base and its conjugate acid).
When a strong acid is added to a buffer system, the weak acid component of the buffer system reacts with the added acid, resulting in the formation of its conjugate base. This reaction helps to neutralize the added acid, preventing a large change in the pH of the solution.
For example, consider the buffer system made up of acetic acid (CH3COOH) and its conjugate base acetate (CH3COO-). When a strong acid, such as hydrochloric acid (HCl), is added to this buffer system, the acetic acid component of the buffer reacts with the added HCl, producing its conjugate base, acetate (CH3COOH + HCl → CH3COO- + H2O + Cl-). This reaction helps to neutralize the added acid and maintain the pH of the solution.
To answer the second part of your question, neither H2CO3 nor NaOH3 exists as a chemical compound. The correct formula for carbonic acid is H2CO3, and sodium hydroxide is NaOH.
When a strong acid is added to a buffer system containing carbonic acid and its conjugate base, the carbonic acid component of the buffer system reacts with the added acid. Sodium hydroxide is not typically part of a buffer system, so it would not react in this context.

Explanation:
A researcher is investigating the of effects a chemical that makes thylakoid membranes permeable to hydrogen ions (H+). Which of the following is most likely direct effectof adding the chemical to plant cells?
Answer:
B. The chloroplasts will generate less ATP
Explanation:
Photosynthesis, occurs in the chloroplasts of plants. Solar energy is converted into chemical energy in the form of stable carbohydrates.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
Chloroplasts, are small membrane-bound organelles of multi-folded membranes containing pigments, enzymes, and other molecules that facilitate the process. The thylakoid contains multiple folded membranes called granum stacked together. They contain light-absorbing pigments like chlorophyll.
Here, absorbed light is used in photolysis, to split water produce H+, O2 and high-energy electrons for the high-energy producing electron transport chain.
Protons are pumped into the stroma within granum, producing ATP. ∴ Without ATPase, less ATP is produced.
Chloroplasts are the membrane-bound organelles, which carry out the process of photosynthesis. The correct answer is:
Option B. The chloroplasts will generate less ATP.
Photosynthesis is the process of preparing the food in presence of sunlight. It occurs in the plant. The chloroplasts are the membrane-bound organelles, which consists of pigments, enzymes, and other molecules. The thylakoid membrane consist of stacked membranes, known as grana. The light-absorbing pigment, chlorophyll is found in grana.
The following points can be used to explain photosynthesis:
The absorbed light initiates photolysis, which is the breakdown of water molecule into hydrogen and oxygen. During photolysis, high-energy electrons are also released. These electrons are utilised in the electron transport chain to provide energy.Therefore, the permeability of the protons into the granum will yield ATP. The less ATP will be produced without ATPase.

The electrons in a bond with electrons held tightly by oxygen:
a. are completely transferred from one atom to the other.
b. are loosely held between the two atoms forming the bond.
c. give rise to positive and negative partial charges.
d. are equally attracted by both atoms forming the bond.
e. give rise to full electrical charges.
Answer:
C). Give rise to positive and negative partial charges.
Explanation:
As we know, electronegativity is characterized as the ability of an atom or molecules to attract electrons and form bonds, and Oxygen is one of the electronegative elements in the periodic table. The other electronegative elements are Fluorine and Nitrogen. Thus, the oxygen would be able to 'attract electrons towards it' and this will lead to having a partial negative -ve charge on oxygen itself and partial positive +ve charge on the other atom. Thus, option C is the correct answer.

A drop of blood returning from the big toe would enter the heart through what vessel?
O Pulmonary veins
O Coronary sinus
Inferior vena cava
O Azygous vein
O Superior vena cava
Answer:
The inferior vena cava
Explanation:
A drop of blood returning from the big toe would enter the heart through the inferior vena cava.
The inferior vena cava is a blood vessel that is located near the heart, with the aim of receiving the blood that has already traveled through the abdominal cavity and the lower extremities.
The inferior vena cava originates at the level of the pelvis, when the external iliac vein and the hypogastric vein come together to create a system that collects the blood waste that has already traveled both legs.Therefore, together with the superior vena cava and the coronary sinus, they are the ones that carry blood to the right atrium.Therefore, we can conclude that the superior vena cava collects deoxygenated blood that comes from the abdomen, pelvis, and lower limbs.

when on enzyme is subject to excess heat
Answer:
Enzymes rely on molecular movement and collisions with the compounds they are meant to bind with -- called substrates -- so they can speed up certain chemical reactions. Increases in temperature increase molecular activity, and can result in a higher rate of collisions between enzymes and substrates. If the temperature rises too high, however, the enzymes could become denatured, and the positive effects of the temperature increase could be nullified.
Explanation:
Many enzymes lose function at lower and higher temperatures. At higher temperatures, an enzyme's shape deteriorates. Only when the temperature comes back to normal does the enzyme regain its shape and normal activity unless the temperature was so high that it caused irreversible damage.
