discuss the functions and deficiency symptoms of phosphorus
Answer:
Functions of phosphorus in the body,
i) Formation of bones and teeth. It's a component necessary for forming strong bones and teeth in the body.
ii) It's important in helping to make protein in the body for growth. Since many proteins in the body are phosphorylated for regulating their functions.
iii) Activation of enzymes. This done through phosphorylation.
iv) Gene transcription. It provides structural importance to the gene and protein binding is by the presence of phosphorus.
Deficiency of phosphorus in the body;
i) Weak and fragile bones.
ii) Bone pain.

What happens to air as it is moved into the body?
*it's D
Answer:
all of the above
Explanation:
Answer:When you inhale (breathe in), air enters your lungs and oxygen from the air moves from your lungs to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathe out). This process is called gas exchange and is essential to life.

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.

which of the following are electron carriers in many important cellular processes?
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:
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
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.

a muscle fiber is what level of organization in the body?
A muscle fiber is a CELLULAR level of organization in the body. A muscle fiber is a single muscle cell.
A muscle fiber consists of myofibrils, which are in turn composed of a series of sarcomeres linked in linear order.
The sarcomere represents the functional unit of muscle fiber cells.
Each bundle of muscle fibers is known as fasciculus.

what are the scientific importances of studying anatomical features of angiosperns
Answer: All angiosperms are comprised of stamens which are the reproductive structures of the flowers. They produce the pollen grains that carry the hereditary information. The carpels enclose developing seeds that may turn into a fruit. The production of the endosperm is one of the greatest advantages of angiosperms.

Machines known as “DNA synthesizers” can produce short pieces of DNA.
True or false
Answer:
Machines known as DNA synthesizers are used to produce short pieces of DNA, up to several hundred bases in length. These synthetic sequences can then be joined to natural sequences using DNA ligase or other enzymes that splice DNA together. A gene from one organism can be attached to the DNA of another organism.
