Design your own experiment to test how your body changes during exercise. You may develop this new experiment to test the changes in heart rate, breathing rate, or any other parameter occurring during exercise.
First, formulate a question to answer through scientific investigation. Keep in mind that you should be able to answer your question with measurable data. Write your question here.
Write your plan for the experiment. Note the dependent and independent variables. To ensure that your results test only the dependent variable, consider how you will control outside factors.
Write down your prediction about the result of the experiment.
Carry out your experiment and record your readings in the form of a table.
Based on the results shown in the graph, write a conclusion paragraph that answers the following questions:
Did you accurately predict the results?
What can you conclude from the results?
Can you relate your results to the body’s regulation of homeostasis?
Were there any limitations on your experiment?
How could you improve the accuracy of your experiment if time, access to resources, and cost were not issues?
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.

Where in your body do you think cell division is occurring?
Answer:
Everywhere except in gonad cellsExplanation:
Cell division by mitosis occurs in all human body cells except the gonads (sex cells). During mitosis, the DNA is exactly copied and a new daughter cell created with the same number of chromosomes as the parent cell, ie 46. In the sex cells, meiosis occurs where the DNA is halved and the daughter cell has only 23 chromosomes.

Answer:

ATP is the energy currency of the cell and it is required almost everywhere. 4 cellular activities that would require the energy of ATP will be cellular respiration, ion transport, muscle contraction, nerve impulse.
What is the role of ATP ?The role of ATP is providing energy where it gets hydrolysed into ADP along with the phosphate ion where the reaction provides energy and this reaction brings about energy in the activity.
The cellular activities are the activities that take place inside the cell and various activities that will link to them in order to perform various functions. DNA synthesis, biochemical reactions, cellular respiration, cellular activities all takes place with the help of ATP.
Therefore, ATP is required almost everywhere in both cellular respiration activities and cellular activities.

D. Some use O2 (oxygen), and others do not.
Explanation:
Bacteria can either grow aerobically or anaerobically. Because of their ability to respire and ferment organic substances, these types of bacteria (facultative anaerobes), can continue growing in the presence or the absence of oxygen.
Hope this helps! Please Mark BRAINLIEST.
Answer:
They would perform aerobic processes.
Explanation:
When exposed to a lack of oxygen, facultative anaerobes develop metabolic processes with oxygen, like respiration. But in the absence of oxygen, they can develop processes like fermentation. When in oxygen, they prefer the use of it, because that's what makes them facultative, the fact that they're able to work in both circumstances. Otherwise, tolerants are able to survive but not to work properly, in different environments.

I need help writing an essay on pollution can anyone help me! I'll give you the Brainliest answer!! I really need help! It can be any topic of pollutions
like firecrackers, greenhouse affect etc...
Answer:

Explanation:
bok choy is causing pollution
brainly plz
Answer:
hehe i just finished answer a question about pollution sooo here you go :) this is just an example and not a full essay I recommend adding more evidence!! (please write in your own words)
Pollution has been a problem for over 2,000 years now. There are many things that are causing pollution. For example firecrackers!
Using firecrackers can be very dangerous not just for us, but the environment as well. Firing crackers can increase the concentration of dust and pollutants in the air. After firing, the fine dust particles settle on the surrounding surfaces which are packed with chemicals like copper, zinc, sodium, and lead. Now you may think oh so it's bad for the air so what? If the air is polluted, trees and plants that give us oxygen can't do their job. If they can't do their job we can't breathe or live. Most of the chemicals that are bad for the air are in firecrackers. These chemicals can last for hours or days on end, exposing you and your neighbors to possible long-term health problems. Then fireworks also have the potential of starting wildfires. About 7,500 to 10,600 trees were burnt down (10% to 14% of trees) in California alone due to wildfires. About 19,500 trees were burnt down just from fireworks.
give example on substitutions for frieworks. I would recommend adding more information about how the chemicals in the firecrackers are dangerous for the air. Since I didn't go into full enough details (if you don't you might get marked down for not having enough details or evidence)

what will happen to a population of organisms that are in an environment with little to no oxygen?
Answer:
Hypoxia occurs when algae and other organisms die from lack of oxygen and available nutrients. Hypoxia events often follow algal blooms. The cyanobacteria, algae, and phytoplankton sink to the seafloor, and are decomposed by bacteria. This lack of oxygen creates dead zones in which most aquatic species cannot survive.

what de-polymerizes microtubules to separate sister chromatids during anaphase?
Mitotic spindles depolymerize microtubules to separate sister chromatids during anaphase.
What are microtubules?Microtubules are present inside the cell. They are present in bundles, and they are together with a group of 9 to 11 microtubules. They are rigid and hollow from the inside. They are part of the exoskeleton.
Regarding how chromosomes travel during anaphase A, there are two primary theories. One is that the chromosomes are pulled along the kinetochore microtubules by motor proteins at the kinetochores using the energy from ATP hydrolysis, which causes the microtubules to depolymerize.
Therefore, the microtubules are separated or depolymerized by spindle fibers, to separate the sister chromatids into lines.
