Answer:
1. Check your pulse before doing the stair master. Do 2 minute intervals on the stair master then check your heart rate again. What is the difference between your heart rate before and your heart rate now?
2. Going up the stairs for 2 minutes and looking at heart rate differences is the expierement. This should last about 10 minutes. An oximeter needs to be used for best results on the heart rate. The excercise should be as consistant as it can be.
3. Your heart rate should keep increasing until you reach your max heart rate
4. 2: 72
4: 78
6: 82
8: 100
10: 118
5. just copy numbers into graph
6. My predictions were pretty accurate. Your heart rate should gradually rise until you hit your max heart rate. The body needs more oxygen to maintain homeostasis which leads to increased heart rate. I didn't track how fast we were going every 2 minutes (I didn't stay at the same speed as I did in the beginning). Not changing the speed as time goes on and monitering the speed.

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:
1,100 + 100 + 415 + 35 = 1,650 calories in total

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

If an experiment was being conducted using an enzyme that was very sensitive to changes in pH (which could result in denaturation), what should be added to the experiment to prevent the enzyme from denaturing?
A. a buffering solution
B. extra substrate
C. an acid
D. a base
Answer:
maybe the answer is C..sorry if i wrong
If an experiment was being conducted using an enzyme that was very sensitive to changes in pH, a buffering solution must be added in order to prevent the enzyme from denaturing. Thus, the correct option for this question is A.
What is the denaturation of an enzyme?The denaturation of an enzyme may be defined as a process through which a molecular structure of an enzyme gets deviate from its original state due to exposure to high temperature, pH sensitivity, etc.
The function of a buffering solution is to stabilize the pH of the given solution. It helps the other component of the solution to resist in response to pH change. A Buffer solution is capable to neutralize the effect of the small amount of acid or base.
Therefore, a buffering solution must be added in order to prevent the enzyme from denaturation. Thus, the correct option for this question is A.

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 does a plant obtain the water it needs for photosynthesis?
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.
