5. (Climate, Seasons): the four divisions of the year based on changes in temperature caused by
varied amounts of sunlight and the tilt of Earth.
Answers
Answer:
1. solar system
The galaxy is much larger than the solar system, and since the question only includes the sun and the other planets, and what's close to that like debris, we should limit this to the solar system.2. eclipse
A black hole is a discontinuity from which light cannot escape. It's by no means partial or temporary, unlike an eclipse, which is when a celestial body covers another (like when the moon temporarily covers the sun).3. axis
The equator is like the circumference of the sphere, and the axis is like a diameter that goes straight through the earth. The axis goes from pole to pole, which is through the earth, so you know it's the correct answer.4. cyclic pattern
"Cyclic" comes from "cycle" which means a consistent pattern. "Sporadic" means with no pattern, capricious.5. seasons
There are four seasons and there aren't four climates, so this should be fairly simple!Related Questions
Glycolysis that starts with glycogen instead of glucose can be considered to have a higher energy yield because:
A. Phosphorolysis reactions cleave bonds with phosphate instead of water.
B. Phosphorylase is a better enzyme than hexokinase
C. Phosphorylase produces a glucose phosphate without spending an ATP to do it
D. All of these
Answers
Answer:
A
Explanation:
The answer is a Because Phosphorolysis reactions cleave bonds with phosphate instead of water (: just trust me
Glycolysis that starts with glycogen instead of glucose can be considered to have a higher energy yield because phosphorolysis reactions cleave bonds with phosphate instead of water. The correct option is A.
What is glycolysis?Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons.
The metabolic process that changes glucose into pyruvate is known as glycolysis.
The high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process. A series of ten enzyme-catalyzed processes make up glycolysis.
In contrast to phosphorolysis reactions, which cleave bonds with phosphate rather than water, glycolysis can be thought of as having a larger energy yield because it begins with glycogen rather than glucose.
Not producing adenosine 5′-triphosphate is not the primary goal of glycolysis; rather, it is to produce pyruvate for the trichloroacetic acid (TCA) cycle.
By boosting the ratio of NADH to NAD+, the glycolytic synthesis of pyruvate lowers the cytosol.
Thus, the correct option is A.

A student is given five samples and told they are lysine (an amino acid), lactose (a disaccharide), insulin (a protein hormone), RNA and fat. The samples are in test tubes marked 1-5, but the student doesn't know which compound is in which tube. The student is instructed to identify the contents of each tube. Base on these data, identify what is in each tube. In her first test, she tries to hydrolyze a portion of the contents of each tube. Hydrolysis occurs in all tubes except tube 3. In the next test, she finds that tubes 1, 2, and 3 are positive for nitrogen but only tube 2 gives a positive result for the presence of sulfur. In the next test the student shows that the compound in tube 1 contains a high percentage of phosphate. In the final test the student shows that compound 5 is hydrophobic. Base on these data, identify what is in each tube. 1 2 3 4 5 A. lactose B. RNA C. lysine D. fat
Answers
Answer:
1. RNA 2. Insulin 3. Lysine 4. Lactose 5. Fat
Explanation:
RNA contains both nitrogen and phosphate hence it is the substance in tube 1.
Insulin being a protein contains sulfur hence it is the substance in tube 2.
Lysine does not hydrolyse hence it is the substance in tube 3.
Fat is hydrophobic hence it is the substance in tube 5.
Since lactose does hydrolyse and because the rest have been identified, it must be the substance in tube 4.
Based on these data, each tube is identified as:
tube 1: RNAtube 2: Insulintube 3: Lysinetube 4: Lactosetube 5: Fat1. first testHydrolysis doesn't occur in lysine so, the 3rd tube contains lysine.
2. second testNitrogen is present in Insulin(in amino acids), RNA(in nucleotides), and Lysine. Insulin consists of two polypeptide chains (A and B) which are joined by sulfur bonds. So, 2nd tube contains insulin.
3. third testIn RNA, nucleotides are present which consists of phosphate groups. Adjacent nucleotides are joined together by phosphodiester bonds. So, 1st tube contains RNA
5. 4th testFatty acids are Hydrophobic due to the presence of long hydrocarbon chains. So, 5th tube contains Fat.

Fossil fuels are cheaper than alternative forms of energy.
Fossil fuel reserves will never be depleted.
Fossil fuels are easily renewed.
Fossil fuel use does not affect the environment.
Answers
Answer:
The correct answer is - Fossil fuels are cheaper than alternative forms of energy.
Explanation:
Fossil fuels are made by the natural process in a longer time period such as anaerobic decomposition of the dead organism like plants, and animals. These plants and animal's decomposed organic matter pilled up to form coal, or natural gases or crude oil.
By the use of such fuels the reserves are continuously depleting and will be no longer available in the future if not managed properly as it can not be renewed. Fossil fuels increases the green house gases in environment and affect it by incresing carbon in atmosphere. However, these fuels are cheaper in comparision of other fuels.

4. what tissues can humans regenerate? why might we not have widespread regeneration abilities?
Answers
Humans are capable of regenerating a few tissues, including the liver, skin, and blood vessels.
Despite this, widespread regeneration abilities are limited for various reasons.The human body can regenerate a few tissues, including the liver, skin, and blood vessels, and bone marrow.
There are many types of cells in the human body, each with its own function. Some cells, such as neurons and muscle cells, are very complex, and it is challenging to replace them when they die or become damaged.
Cells must function together for an organ to work properly. When a cell dies or becomes damaged, it can have a domino effect, causing other cells to die as well.
As a result, the healing process is more complicated in certain organs than in others. Widespread regeneration of these cells would result in significant problems for organ functions.
Finally, the human body's natural healing abilities are restricted by genetics. Regeneration is not a process that humans can actively initiate; instead, it occurs naturally.
The body's genetic makeup determines how well it can regenerate, and some individuals have a greater regenerative ability than others.

Questions:
1. Can either man be excluded as the father? Explain.
2. Which man may be the father of the child? Explain.
3. Is this DNA profile sufficient to establish paternity? Why or why not?
Answers
In a DNA profile, bands should be compared to establish paternity. 1) Alleged father number 1 could be excluded. 2) Alleged father number two may be the father. 3) No, more markers and repetitions are needed.
What is a genetic profile?The genetic profile is the series of alleles characteristic of each individual concerning a series of DNA fragments. Once genetic profiles are obtained by using PCR/electrophoresis, they must be subjected to interpretation. The researcher must compare profiles to find concordance between individuals or the lack of it. How to improve the study?Using several markers in the study increases the matches chances. There must be a repetition of the study.In the exposed example, we have a profile of the mother, the child, and two potential fathers.
We need to find out which of the two men might be the father.
How to interprete the results from the pattern of bands?We need to compare the child's pattern of bands with the mother's ones and each of the potential fathers.We need to look for the child's lanes that match the most with each of the potential fathers' lanes and discard those that differ the most. These patterns that differ the most can be excluded. Individuals suspected to be related must be subducted to a repetition of the study. As the statement says, any band that does not matches the mother's side comes from the father's side. ComparisonMother-Child ⇒ In these profiles, the child only matches one band with the mother. You will find this match as a red circle in the image in the attached files. 1st profile ⇒ In this profile, the child does not match with any of the bands of the first alleged father. 2nd profile ⇒ In this profile, the child matches with only one of the bands of the second alleged father. You will find this match as a green circle in the image in attached files.1. Can either man be excluded as the father? Explain.
Yes. Concerning only the analyzed markers, we could say that alleged father number one can be excluded since there is no bands' matching. This man is the one that differs the most.
2. Which man may be the father of the child? Explain.
Since one of the bands match, the alleged father number two may be the child's father.
3. Is this DNA profile sufficient to establish paternity? Why or why not?
A deeper study should be done to establish paternity, which includes more markers and more repetitions. There should be more than only one matching band.

Weathered rock (low precip.)
Answers
The amount of precipitation significantly affects the amount of weathering experienced by weathered rock. In regions with low precipitation, the weathering process is slower due to reduced moisture availability.
Water is a critical agent in various types of weathering, including chemical and physical processes. With low precipitation, the rock is exposed to limited moisture, hindering chemical reactions and reducing the frequency of freeze-thaw cycles. As a result, the overall rate of weathering decreases.
Regions with high precipitation witness accelerated weathering rates. Abundant rainfall increases the frequency of wetting and drying cycles, leading to enhanced chemical reactions and physical breakdown of the rock. The presence of water facilitates chemical weathering processes such as dissolution and hydrolysis, which act upon mineral constituents.

A student working on their science experiment places four potato squares into solutions of Iodine and measures how far the Iodine diffuses into the potato. The measurements are: 2.1 mm, 1.8 mm, 2.3 mm, and 2.2 mm. What is the average diffusion distance?
Answers
Answer:
The average diffusion distance is 2.1 mm
Explanation:
Given
Diffusion distance of the four potato squares are;
\(Potato 1: 2.1 mm\\Potato 2: 1.8 mm\\Potato 3: 2.3 mm\\Potato 4: 2.2 mm\)
Required
Average Diffusion Distance
To calculate the average diffusion distance; we simply calculate the mean of the student recordings
Mean is calculated as thus;
\(Mean = \frac{\sum x}{n}\)
Where x is the individual distance of the potato squares
\(\sum x = 2.1 mm + 1.8 mm + 2.3 mm + 2,2 mm\)
\(\sum x = 8.4mm\)
n is the number of potato squares
n = 4
\(Mean = \frac{\sum x}{n}\)
\(Mean = \frac{8.4 mm}{4}\)
\(Mean = 2.1 mm\)
Hence, the average diffusion distance is 2.1mm
explain the concept of feedback in terms of negative and positive feedback. give examples and relate feedback to the endocrine system
Answers
The concept of negative and positive feedback is based on the amount of secretions of hormones which changes the final output of the body parameters.
Feedback mechanism is an ideal way of controlling hormone levels as they involve constant monitoring and regulations to keep hormone levels stable (in control). It is essential because Hormones can affect target organs at low concentrations so even a small quantity can have drastic effects on the body. Also, the length of time during which hormones remain active is variable which affects the secretion. Positive feedback means amplified secretion so that body drifts away from equilibrium condition. Negative equilibrium means suppressed secretion so that body drifts towards the equilibrium condition. These feedbacks helps in maintaining endocrine system in stabilized form.

what situation shows kinetic energy being transformed into potential energy ???????????
Answers
A situation of kinetic energy being transformed into potential energy is when an object is lifted upward.
As the object is lifted, its potential energy increases while its kinetic energy decreases. This is because the object has the ability to do work due to its position, or potential energy, and as it is lifted higher, the amount of potential energy it possesses increases. Conversely, as the object is lifted, its speed, or kinetic energy, decreases.
This is because work is being done on the object to lift it, which reduces its kinetic energy. Overall, as the object is lifted, its kinetic energy is being converted into potential energy.

Why do only certain cells respond to particular signaling molecules that are sent throughout the body
Answers
Answer:
The presence of appropriate receptor dictates which cells will be receptive to a particular signal.
Explanation:
Some cells only respond to certain molecules because they have receptors to accept those molecules. Hence, due to this, only some molecules can be accepted by the cells.
How does a particular cell accept the molecules?Hormones are secreted by endocrine glands into the blood. The endocrine glands, such as the pituitary gland, secrete their hormones directly into the blood, but not all cells of the body can bind to the molecule and perform the cellular functions.
The cells' surface has receptors for molecules such as peptide molecules or polar hormones that can't directly enter the cell. Hence, they bind to the cell surface receptors and send signals with respect to those hormones.
A hydrophobic hormone can directly enter the cell as it can easily pass the plasma membrane. After entering the cell, it has some receptors in the nucleus or in the cytoplasm. This hormone can perform functions such as gene activation after binding with them.
Hence, after binding with receptors, they show their performance, and not every cell has the same receptors for a single molecule.
