The study of a cell is called cell biology.
The division of the old cell to make the new cell is called cell division or cell cycle.
In the cell cycle, there are two-phase. These two phases are as follows:-
InterphaseM- phase.There are 4 phases in the M -phase, out of which the two-phase is telophase and anaphase.
In anaphase, it is considered as the splitting of the chromosome.
In telophase, it is concerned with the packing of new divide chromosome.
Hence, the answer is mentioned above.

Explanation:
in an experiment what should be the relationship between the control group and experimental group?
Answer:
Ideally, the experimental and control groups are identical. As much as possible, the two groups should overlap in every characteristic.
Explanation:
At the beginning of your study, you need your two groups to be as statistically similar as is humanly possible. That way, when you control for other variables, you can reasonably attribute any statistically significant differences at the end of the study to your intervention.

A.Cells to repair damage in an organism
B.Cells for the growth of an organism
C.Cells that are gametes
D.Cells with identical genetic material to the parent cell
Answer:

Compared to healthy dog, did the enzymes from Claire’s stomach break down the protein at a low, normal, or high rate?
Answer:
Norma Rate
Explanation:
Represents exponential growth
Answer:
The variable b represents the growth or decay factor. If b > 1 the function represents exponential growth. If 0 < b < 1 the function represents exponential decay. When given a percentage of growth or decay, determined the growth/decay factor by adding or subtracting the percent, as a decimal, from 1.

Why do the cells of the digestive system secrete proteolytic enzymes, such as pepsin, in their inactive forms
Answer:
In the initial stages of digestion of food, the stomach performs an essential role. Apart from doing churning and squeezing the food bolus, it also discharges an amalgamation of compounds, together called gastric juice. It comprises mucus, water, pepsin, HCl, and intrinsic factor. Of these five constituents, the principal enzyme that takes part in the digestion of protein is pepsin.
It dissociates proteins into amino acids and smaller peptides, which can easily get captivated within the small intestine. This pepsin is released in its sedentary form, or zymogen form called pepsinogen by the chief cells present within the gastric lining. It is released in its sedentary form by the stomach, by this the stomach inhibits the auto-digestion of defensive proteins in the digestive tract's lining.

How is land subsidence related to a rise in human population?
Land subsidence happens when the increased demand for water is countered with sound agricultural practices.
Land subsidence happens when the increased demand for water causes the levels of the water table to rise.
Land subsidence happens when the increased demand for water causes the levels of the water table to lower.
Land subsidence happens when the increased demand for water results in rapid recharging of aquifers.
Land subsidence is related to human population growth because soil subsidence occurs when increased water demand causes groundwater levels to drop.
What causes subsidence?Subsidence is a phenomenon of lowering of the ground surface due to changes in the underground support. The phenomenon occurs in several places in the world due to the
extraction of wateroil and gas from the subsoil.With this information, we can conclude that Land subsidence is related to human population growth because soil subsidence occurs when increased water demand causes groundwater levels to drop.

white eyes are recessive in flies. can two red eyed flies have white eyed offspring
Answer:
Considering that white eyes are a recessive trait in flies, it is possible for two red-eyed flies to have offspring with white eyes only if both are heterozygous for this trait.
Explanation:
For two individuals with dominant phenotype for a trait to have offspring with the recessive trait, both must have a heterozygous genotype.
In the case of the characteristic eye color of the flies :
Red eye (R) is dominant trait. White eyes (r) is the recessive trait.When both parents are heterozygous, their genotype is Rr
In Punnett Square it can see the result of the crossing of these individuals:
Punnett Square :
Rr X Rr
Alleles R r
R RR Rr
r Rr rr
In the offspring, the probabilities are:
50% heterozygous individuals Rr, with red eye phenotype. 25% pure dominant individuals RR, with red eyes 25% individuals with the recessive rr genotype, white eyes.This is the possibility of two red-eyed flies having white-eyed offspring.

why the food pyramid is wider at the base and very narrow at the top
Answer:
The wider base stands for foods with little or no solid fats or added sugars. These should be selected more often. The narrower top area stands for foods containing more added sugars and solid fats. The more active you are, the more of these foods can fit into your diet.
Explanation:
A food pyramid can be defined as a graphical representation of a set of dietary guidelines and optimal number of servings from each of the basic food groups, which are to be eaten daily by an individual.
Basically, a food pyramid illustrate the principles of good nutrition and contribute towards a healthy balanced diet.
Foods and drinks that are highly rich in nutrients such as fruits and vegetables are found at the wider base (bottom) of the food pyramid while foods that are high in sugar, cholesterol, salt and fat are placed at the top.
In conclusion, the food pyramid is wider at the base because that is where all the very good and nutritious foods are illustrated while it is very narrow at the top because those are unhealthy foods and drinks for humans.

Which of the following explains how photosynthesis takes place in a plant?
Answer:
D
Explanation:
Carbon dioxide enters through the stomata on the underside of the leaf.
Water is absorbed by the root hair cells and is transported to the leaf by the xylem vessels.
Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).
Oxygen is released through the stomata on the underside of the leaf; glucose is transported around the plant in the phloem vessels.

A corn field is divided into four parts each part is ‘treated’ with a different fertilizer to see which produces the most corn. What is the dependent variable?
1. Different Fertilizers
2. Corn Production
Answer:
The correct answer is - 2. corn production.
Explanation:
The dependent variable of a scientific investigation is a variable that depends on the independent variable. It is a variable that is required to check or find the effect of the independent variable and also known as output value that helps to know the effect of input values or independent variable.
In this case, the input value or the independent variable is different fertilizer as it is the only variable that is manipulated by the researcher, and due to this manipulation, the production of the corn affected which is the dependent variable as it depends on the independent variable.
