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

where are the motor proteins that move chromosomes toward the poles of the mitotic spindle located?
Answer:
They are at or near the ends of the microtubules. I hope this helps you! :D
Microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.
What are motor protein?Motor protein are defined as a group of molecules with the ability to travel across the cytoplasm of animal cells. Molecular motors called motor proteins move along the cytoskeletal filaments of the cell by hydrolyzing ATP. They provide a variety of tasks for biological systems, such as facilitating intracellular trafficking along biopolymer filament tracks and regulating filament sliding during muscle contraction.
Microtubules are defined as the cytoskeleton is made up of tubular-structured polymers, which are present throughout the cytoplasm. Microtubules play a variety of roles in dividing cells, including the construction of the mitotic spindle and axon extension in neurons.
Thus, microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.

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.

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.

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.
