A student uses gummy worms to model the process of mitosis. The model is shown below.
Using the model, which statement correctly explains how mitosis preserves genetic continuity?
A
The daughter cells receive chromosomes that are recombined from the parent cells.
B
The daughter cells receive chromosomes that are identical to the parent cell.
С
Each daughter cell receives half of its chromosomes from each of the parent cells.
D
Each daughter cell receives twice as many chromosomes as the parent cell.
Each developing daughter cell obtains one set of chromosomes when mitosis comes to a finish. Thus, option C is correct.
What is genetic continuity of Mitosis?
According to the definition of mitosis, a cell divides into two so that each has the same amount of DNA as the original cell by dividing its nucleus and DNA.
When a single cell divides into two cells through mitosis, genetic continuity occurs.
One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.
As the cell divides through the cytokinesis process, the nuclear membranes come back. Mitosis maintains genomic stability throughout successive generations of cells in this manner.
Therefore, Each daughter cell receives half of its chromosomes from each of the parent cells

What do adenine, ctyosine, guanine, thymine, and uracil have in common
Adenine and guanine have a fused-ring skeletal structure derived of purine, hence they are called purine bases. ... Similarly, the simple-ring structure of cytosine, uracil, and thymine is derived of pyrimidine, so those three bases are called the pyrimidine bases.
which molecules determine the tissue specificity of hormones?
Answer:
Steroids. Which molecules determine the tissue specificity of hormones? Receptors. Hormones bind to receptors on target cells and trigger a cellular response.
Explanation:
The tissue specificity of hormones is determined by hormone receptors. Proteins called hormone receptors are found on the cell surface. A hormone's binding to its receptor starts a chain of actions that eventually affects the activity of the cell.
For various hormones, different cells have various receptors. This implies that a hormone can only attach to cells that also contain such receptors. The tissue specificity of hormones is a result of this.
For instance, the insulin hormone attaches to receptors on cells in the muscle, fat, and liver tissues. These receptors bind to insulin, which sets off a series of processes that eventually result in the absorption of glucose from the circulation by these cells.

How does biotic carbon change to the abiotic form of carbon
Answer:
A balanced carbon cycle is essential. Carbon is a major component in carbohydrates, fats and proteins. The carbon cycle involves the exchange of carbon between living organisms (biotic) and their atmosphere (abiotic). In the carbon cycle, carbon is constantly removed from, and returned to, the environment.

Suggest why the blood flows through many channels in the dialysis unit, rather than through a single large channel
Hello there I hope you are having a great day :)
Blood travels through many different channels to optimize absorption. The water potential in the solution in the dialysis machine will need to be less than in the blood. If all the blood flows through a single large channel the blood water potential may be more negative than outside, therefore slowing absorption.

What is the plasma (cell) membrane? What is its main function?
The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment.
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

pleiotropy
Answer:
D.) pleiotropy
Explanation: Just took the quiz.
Pleiotropy arises when one gene affects two or more seemingly unrelated phenotypes. A pleiotropic gene expresses many phenotypes. Therefore, option (D) is correct.
What is Pleiotropy?
When one gene influences two or more phenotypic qualities that do not appear to be related to one another, this phenomenon is known as pleiotropy. A gene is said to be pleiotropic if it can exhibit many phenotypic expressions in a single organism.
Phenylketonuria is a condition that serves as a straightforward illustration of a pleiotropy. A slow metabolism of the amino acid phenylalanine in the cells of the body is the root cause of this hereditary condition, which causes phenylketonuria.

how many calories are in an average trick-or-treaters halloween stash?
The number of calories on a Halloween stash depends on the type of candies and the number of units of each. If the stash contains 5 units of each of these candies: chocolate bars, taffies, lollypops, and candy corn the total number of calories is 1,650.
Calories are the most common unit used to define the energy a specific food gives to your body. For example, an apple has 52 calories, while a banana has 89 calories.
Considering this, in a Halloween stash the calories depend on two factors:
The types of candies or productsThe units of each oneLet's suppose there are 5 units of each of the following candies:
Chocolate barsTaffiesLollypopsCandy cornLet's now calculate the calories
Chocolate bars = 220 calories x 5 units = 1,100 caloriesTaffies = 20 calories x 5 units = 100 caloriesLollypops = 83 calories x 5 units = 415 caloriesCandy corn = 7 calories x 5 = 35 caloriesAdd all the previous results:
