Answer:chain-link fence

Explanation:a cell membrane is partial permeable which means that it lets some substances through but not other.

Answer:

Chain-link fence

Explanation:

Cell membranes are barriers that decide which molecules enter and exit the cell, and how much of them come in. So things are able to pass through them.

If it were a brick wall, it would not let anything pass through.

So it is more like a chain-link fence, but with more control over what passes through it.

I think it's Coastline

Answer:

0.2um

Explanation:

take each of the answers multiply by 40 and see which the answer is 8um

0.2×40=8um

The diameter of the bacterial; cell would be 0.02 micrometer therefore the correct answer is option A.

It is defined as the multiplication factor used for the design of an object with respect to some other object. the scale is generally used to design prototype designs of large objects.

It is multiplied by the design dimension to get the actual size of the object or product.

As given in the problem A red blood cell is 8 micrometers in diameter. If a bacterial cell is 40 times smaller, then we have to calculate and calculate the diameter of the bacterial cell.

scale factor = 40

diameter of the bacterial cell = 8 micrometers/40

                                                 = 0.02 micrometers

Thus, the correct answer is option A.

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

Explanation:

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.

The mountain was formed by a series of volcanic eruptions. Option D

The geologist can infer from the data that the mountain was created by a sequence of volcanic explosions. It is stated that the mountain is composed of numerous, generally uniform strata of igneous rock.

In most cases, molten material such as lava or magma that is ejected during volcanic eruptions solidifies to produce igneous rock.

Multiple igneous rock strata may accumulate over time while the volcanic activity persists, eventually producing a mountain.

Answer:

1: The higher the force applied to the ball, the harder to make a home run because of the third law: every action has a reaction, the reaction is absorbed by the bat.

2:Same equation: F=MA from the second law, if the ball has a higher mass, it will have a higher force.

Explanation:

The third rule, which states that every action has a response, which is absorbed by the bat, makes it tougher to hit a home run the more power is given to the ball.

Newton's laws of motion are three fundamental physical laws that describe the behavior of objects in motion and how they interact with forces. The laws were first published by Sir Isaac Newton in 1687.

Law of Force and Acceleration - The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. This law is often expressed as F=ma, where F is the net force acting on an object, m is the mass of the object, and a is the acceleration of the object.

Law of Action and Reaction - For every action, there is an equal and opposite reaction. This law states that when one object exerts a force on another object, the second object exerts an equal and opposite force on the first object.

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:

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.

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

Answer:

Explanation:

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.
