A scientist extracts a molecule from a cell that includes phosphorus, a nitrogen base and a sugar. What macromolecule did the scientist most likely extract to
study?
A. Carbohydrate
B. Protein
C. Triglyceride
D. Nucleic Acid

Answers

Answer 1

Answer:

D

Explanation:

The correct answer would be Nucleic Acid.

A typical nucleic acid has 3 components which include:

A purine or pyrimidine nitrogenous baseA phosphate groupA 5-carbon sugar

The purine base includes adenine and guanine while the pyrimidine base includes thymine/uracil and cytosine. The 5-carbon sugar could be ribose or deoxyribose depending on if the nucleic acid is ribonucleic or deoxyribonucleic acid.

The only macromolecule that contains the 3 components of the options A to D is the nucleic acid. Hence, the correct option is D.

how do skin cells replace itself after an injury?

a) skin cells go through the process of budding to make new identical cells.
b) skin cells go through the procces of mitosis to make new identical cells.
c) skin cells go through the process og photosynthesis to make new identical cells.
d) skin cells go through the process of cellular respiration to make new identical cells.

Answers

Answer:

d

Explanation:

as a result of accumulation of waste products in the body , these substances are removed from the body via the skin hence they undergo cellular respiration

Answer:

b) skin cells go through the process of mitosis to make new identical cells.

Explanation:

The skin is the largest organ in the human body; it forms a protective barrier that keeps out external pathogens, and is integral to waste removal. When the organ is injured, damaged cells initiate an immune response, while healthy cells nearby begin to replicate.

This type of cell replication involves somatic cells and results in the diploid number of chromosomes called mitosis. Skin cells are somatic- they contain all 24 pairs of human chromosomes. During replication, the chromosomes are unwound, and copied- then, the newly copied chromosomes separate into two identical daughter cells with the same chromosome number.

What is the source of oxygen as a reactant in cellular respiration?

Answers

Answer:

The Reactants

What goes into the cell? Oxygen and glucose are both reactants of cellular respiration. Oxygen enters the body when an organism breathes. Glucose enters the body when an organism eats.

Explanation:

Hope this helped, Thanks :)

Cellular respiration has been the chemical process that uses glucose to produce energy. Oxygen is the reactant of the process that comes from the air (breathing) produced by photosynthesis.

What is cellular respiration?

Cellular respiration has been defined as the process vital for living organisms that use oxygen and sugar molecules to produce energy to drive the activities and functions of the body. The reactant of the process includes glucose and oxygen gas.

Oxygen and sugar are known to be the product of the photosynthetic reaction that uses carbon dioxide and water. The oxygen gas is present in the atmosphere and enters the body through breathing.

Therefore, oxygen acts as a reactant in cellular respiration that comes from the breathing process.

Stand and let your hands hang next to your sides for a few minutes. Then, look at the backs of your hands. Do you see any bumps on the surface on top of your veins? What might those be, and what are their function?​

Answers

When you stand and let your hands hang next to your sides for a few minutes, the bumps you see on your veins are the valves that help move blood to the larger veins.

What we know about vein valves.

There are valves located throughout the veins in our bodies. Most of these are located in points where smaller venules fuse with the larger veins.

Their function is to prevent blood from flowing back into the smaller veins, thus helping with the normal blood flow of the body.

Given that the veins in our bodies are littered with small valves to help the blood return to the heart correctly, we can confirm that these are the small bumps that we can see when letting our hands down for a few mins, as they fill with the blood they try not to let flow back into the smaller veins.

False

Explanation:

Restriction enzymes, also called restriction endonucleases, are enzymes found in bacteria that cut DNA. They recognise target sequences and cut DNA at or near these sequences. These sequences are called restriction sites.

They act as a defense mechanism against invading pathogens. However, they are routinely used in molecular biology labs to perform DNA technologies such as genetic engineering.

Gand C

Answers

I think it is G and C

Answer: G and C

Explanation:  DNA carries the hereditary information for organisms. W ithout DNA, our species would be unable to pass traits from generation to generation. DNA controls all aspects of an organism. It tells spiders how to spin webs, birds to lay eggs, and what color to make your eyes. The genetic information in DNA is stored as special chemical sequences, called chemical bases. The chemicals bases are adenine (A), guanine (G), cytosine (C), and thymine (T). Each base connects with another to form base pairs. Adenine always pairs up with thymine. Cytosine always pairs up with guanine

5. Describe the role of blood plasma.

6. Explain the role of lymph in our body

Answers

1. Erythrocytes is red blood cells, and anemia means a lack of red blood cells in the blood. So erythrocyte count in a patient diagnosed with anemia such as pernicious anemia is going to be significantly lower than normal.

2. RBC’s (red blood cells) are produced in the bone marrow
3. Platelets help with clotting as well as clotting proteins produced in the liver
4. The human circulatory system is designed specifically to transport oxygen as well as nutrients to all parts of the body through blood vessels. Humans in the womb have blood vessels and a beating heart developed by the 1-2 months in the womb, and the heart immediately begins work. The human circulatory system is efficient because we were created with a system to be as efficient as possible. The circulatory system is basically a highway made of tunnels that allows RBC’s and WBC’s to pass through to every part of the body including major organs. Unfortunately unhealthy eating habits and poor exercise cause this circulatory system to become less and less effective till the point of heart attack, stroke, or major cardiovascular disease.
5. Blood plasma is very important in the transfer of nutrients as well as hormones to the major organs of the body.
6. Lymph is a clear watery substance that carries proteins and other substances throughout the body in order to maintain fluid balance. Lymph is part of the lymphatic system which is a tiny constituent of the immune system.
