Phosphorylation is an example of a post-translational modification of a protein. These modifications are covalently attached to the protein and can have significant effects on its function.

These affects include altering its activity, its binding to other proteins, and where it is found in the cell.

However, post-translational modifications do not affect the amino acid sequence of the protein.

What would happen to an animal cell with an internal salt concentration of 10% if it were placed in a salt solution with a concentration of 30%?

O The water would move out of the cell and the cell would decrease in size.

O The water would move into the cell and the cell would increase in size.

O The salt would move into the cell and the cell would increase in size.

O The salt would move out of the cell and the cell would decrease in size..​

Answers

Answer:

The water would move out of the cell and the cell would decrease in size.

Explanation:

This question is depicting OSMOSIS, which is the movement of water from a region of high concentration (low solute concentration) to a region of low concentration (high solute concentration) across a semi-permeable membrane. This movement is caused when a concentration gradient forms between the two sides of the membrane.

In this case, an animal cell contains an internal salt concentration of 10% while the salt solution has a concentration of 30%. This means that the animal cell is hypotonic (contains high water concentration) to the salt solution, hence, water would move out of the cell and the cell would decrease in size

The time it takes for an animal to metabolize a drug to a non-detectable levels could be ____ than that of the withdrawal period 

A:Longer
B:Shorter
C:Same time

Answers

A:Longer
The physical effects of a drug wear off faster then your body metabolizes it to be un-detectable

The time it takes for an animal to metabolize a drug to a non-detectable levels could belongerthan that of the withdrawal period. Hence the correct option is A.

The metabolism of a drug refers to the process by which the body breaks down and eliminates the drug from the system. The withdrawal period is the time required after administering a drug during which the animal must not be slaughtered for human consumption to ensure that no residues of the drug are present in the edible tissues.

There are several factors that can influence the metabolism of a drug in animals, such as the drug's chemical properties, the animal's species, age, health status, and metabolic rate. Some drugs may be metabolized relatively quickly, while others may take longer to be completely eliminated from the system.

Hence the correct option is A.

(06.02 MC) Which of the following correctly explains the role of antibiotics in the human body? (2 points) a They break down damaging toxins created by bacteria. b They increase the number of white blood cells in the blood. c They rupture the cell wall or prevent protein synthesis in bacteria. d They reduce the effects of fever, swelling, and inflammation in the body.

Answers

Answer:

The beneficial role of antibiotics in the human body is given because they produce rupture the cell wall or prevent protein synthesis in bacteria.

Explanation:

Antibiotics are a group of drugs that fight bacteria, eliminating them, to cure infectious diseases.

The mechanisms of action of antibiotics aim to break the bacterial protection or interfere with their vital functions to make them unviable:

Destruction of the bacterial wall or membrane. Interference with protein synthesis. Inhibition of the synthesis of nucleic acids.

In general, the effects of antibiotics on bacteria are to rupture the cell wall or prevent protein synthesis. Through these mechanisms, antibiotics eliminate and prevent the reproduction of pathogenic bacteria, thus eliminating the infections they produce.

The other options are not correct because:

    a. Breaking down damaging toxins created by bacteria is an anti-toxin function.

    b. Antibiotics do not increase the number of white blood cells in the blood.

    d. Reduction of the effects of fever, swelling, and inflammation in the body is a function of antipyretics and anti-inflammatories.

Answer:

They rupture the cell wall or prevent protein synthesis in bacteria.
