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.

1. How can studying compounds in plants and animals benefit people? Give an example of how a compound found in a plant has been used to benefit humans.
2. What is meant when describing water as a polar compound?
Please answer what the question is asking exactly many points will be given.
Answer:
It is beneficial to study plant and animal compounds for a multitude of reasons such as Sanitation, Bacterial fighting, and many more. An example of a plant compound that has benefited humanity would be penicillin which is derived from plants, it is considered the first true antibiotic.
Explanation:
Before 1928, humanity had conquered most of its enemies and people were only limited in lifespan by internal mechanisms being disrupted or failing, such as cancer, genetic errors,viruses, and BACTERIA. But in 1928 by accident a scientist discovered penicillin and finally deaths by bacteria were dropping to the point where in the past a mere cut could mean death by bacterial infection when compared to the present, humanity now doesn’t even consider bacterial infection, and that is all due to the power of penicillin and other antibiotics.
Water is a polar compound because there is a positive hydrogen end and a negative oxygen end, this is caused by an uneven electron distribution

the oxidation of one three-carbon molecule into one acetyl coa molecule.
Answer:
The Answer is: pyruvate oxidation
Explanation:
In prokaryotes, it happens in the cytoplasm. Overall, pyruvate oxidation converts pyruvate—a three-carbon molecule—into acetyl CoAstart text, C, o, A, end text—a two-carbon molecule attached to Coenzyme A—producing an NADHstart text, N, A, D, H, end text and releasing one carbon dioxide molecule in the process.

What does the atomic number tell you about the element?
O number of protons
number of electrons
O number of neutrons
O total number of neutrons and protons
Answer:
These two numbers are fixed for an element. The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. The atomic number (also known as the proton number) is the number of protons found in the nucleus of an atom. It is traditionally represented by the symbol Z.
Explanation:
(D) O total number of neutrons and protons

Photosynthesis requires light, water, carbon dioxide, and light absorbing
______.
Answer:
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).
Explanation:

Explanation:
Why did Ibrahim conclude that the dorsal spines were not used to support a hump or to regulate body
temperature?
Chemical composition of dorsal spines provides information about its function as regulation of body temperature.
The dorsal spines were not used to support a hump or to regulate body temperature because of the chemical composition of the spines. Ibrahim found that the spines were made up of bones having few blood vessels and were likely wrapped tightly in skin which can't perform the function of thermoregulation in the body.
In order to regulate temperature of the body, more blood vessels are needed and we know that in dorsal spines the structure is bony and less number of blood vessels so we can conclude that chemical composition of dorsal spines provides information about its function as regulation of body temperature.

Answer:
1. B. NADH
2. B. hydrolysis of ATP.
3. C. ATP is produced from protein.
4. Option C.
5. Option C. Oxygen
6. Option D. Glucose.
7. Carbondioxide.
8. Metabolism.
9. Electron carriers.
10. Electrons.
Explanation:
Cellular respiration is a series of metabolic processes that break down sugars or food to produce energy. ATP is the cellular energy produced during cellular respiration. Cellular respiration requires oxygen which is also called aerobic respiration. There are stages of cellular respiration and they include; glycolysis, pyruvate oxidation, Krebs cycle or citric acid and oxidative phosphorylation. During cellular respiration, glucose is broken down into carbondioxide and water. Along the way, ATP is produced from the processes that transform glucose.
Explanation:
how is anaerobic fermentation similar to aerobic respiration
Answer:
Anaerobic respiration begins the same way as aerobic respiration and fermentation.
Explanation:
However, instead of ending with glycolysis, as fermentation does, anaerobic respiration creates pyruvate and then continues on the same path as aerobic respiration.
Most of the reactions by which energy from carbohydrates is released for use by the cell take place within the?
Answer:
Explanation:
The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP. Some of the energy released is lost as heat.
The release of energy from carbohydrates takes place within the
mitochondria.
The mitochondria is an organelle found within cells and it is regarded as
the power house of the cell. This is because energy is generated in it which
gives the cells power to perform its daily activities.
Energy generated from carbohydrate is usually in the form of ATP and it
involves series of reactions such as glycolysis, kreb cycle etc to ensure
adequate energy yield.
