Which of the following is a nutritional monomer that can be transported in the blood? A. Sucrose B. Maltose C. Alanine D. Dipeptide

Answers

Answer:

Alanine

Explanation:

The nutritional monomer that can be transported in the blood is C. Alanine.

Sucrose and maltose are disaccharides made up of two sugar molecules and are not transported directly in the blood. Dipeptides are formed by the combination of two amino acids, and they are typically broken down into individual amino acids before being absorbed into the bloodstream. Alanine, on the other hand, is an amino acid and can be transported in the blood as part of the body's protein metabolism.

Answer:

The nutritional monomer that can be transported in the blood is option C: Alanine. Alanine is an amino acid, which is a monomer of proteins. Amino acids can be transported in the blood to be used for various cellular functions and protein synthesis.

Which homeostatic process moves particles against a concentration gradient?a. dynamic equilibrium
b. passive transport
c. osmosis
d. active transport

Answers

An active transport is the process by which a substance is transported or transferred from one area to another using a chemical energy in the course. 

As oppose to passive transport, active transport’s key to its description uses energy to be able to transfer the said substance. This is important in a lot of aspects such as providing the needed elements or compounds in cellular activity.

D. Active Transport

Why is the model used to describe the plasma membrane called the fluid mosaic model?

Answers

Answer:

Because proteins and lipid tails are free to move and are not bonded by strong interactions with each other.

Explanation:

The plasma membranes have two layers of phospholipids in which proteins are present. The hydrophobic fatty acid tails of phospholipid layers make the inner core of the membranes. However, the tails are not bonded to each other and make a fluid-like base in which proteins are present. Also, the membrane proteins are not bonded to the phospholipids and are free to change their position within the phospholipid leaflets. This is why the model is described as a fluid mosaic model.

After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?A. Heavy breathing during exercise has produced an oxygen surplus in her muscles. This oxygen is being transported to her lungs. This is a result of aerobic respiration.

B. Heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. Lactate is being transported to her liver. This is a result of aerobic respiration.

C.Strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

Answers

The correct answer is option D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

During exercise, the muscles use the oxygen present there and become deprived of oxygen. Due to less oxygen, the anaerobic respiration occur in the muscles, to overcome this, the heavy breathing takes place. heavy breathing brings the oxygen to the muscles.

During anaerobic respiration, the glucose is broken down into the lactate and the lactate is transferred to the liver for the gluconeogenesis and to maintain the constant supply of the glucose to the muscles.

A simple diagram of Cori cycle (lactic acid cycle) is given below:


Out of the choices given, what is most likely occurring in her body is the strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration. The correct answer is D. 

How can an increase in biodiversity lead to an increase in ecosystem stability?

Answers

Within a more biodiverse ecosystem, there is a higher chance that species will be able to adapt to change. For example, even with the eradication or migration of any one particular food group, consumers higher up in the food chain will remain able to survive due to alternative sources of energy.
