Compare the movement of oxygen and carbon dioxide across the cell membrane

Answers

"As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. ...

4. The human population has experienced unchecked growth for the past 200 years. What does "unchecked" mean? A. Slow b. At a steady rate c. Unrestrained d. Dangerous

Answers

Answer:

B

Explanation:

The correct option would be B

The human population experiencing unchecked growth for the past 200 years does not mean that there were no restraining factors that limit the population. Factors such as death, competition for resources, diseases, etc., were still present.

Despite the limiting factors, the population has been growing. Hence, the correct word to replace 'unchecked growth' would be 'at a steady rate'.

Slow and dangerous really have nothing synonymous with unchecked growth.

The correct option is, therefore, B.

cancer drug Vinblastine interferes with the
synthesis of microtubules. Which process does
Vinblastine interfere with during the cell mitosis?

Answers

Answer:

The correct answer is - disrupting microtubule assembly and proper formation of the mitotic spindle and the kinetochore.

Explanation:

Vinblastine is known for treating cancer cells by sending them to apoptosis. It interferes with the synthesis of microtubules. It binds to the microtubular proteins of the mitotic spindle that causes disrupting microtubule assembly.

It also prevents from proper formation of the mitotic spindle and the kinetochore which is essential to separating chromosomes during anaphase. They arrest mitosis and cause cell death.

How are many unicelled organisms. In addition , anything less than a cell is not alive. What do these statements imply about cells?

Answers

Answer:

The correct answer is - cells are the basic unit of life.

Explanation:

As it is given and also known that there are many unicellular organisms exists and they do not require the multicellular body to live their life or survival. Multicellular organisms are made up of various cells joined together to form a complex organization.

Anything less than a cell can not live or survive and also do not called a living entity. So, from above we can say the basic unit of the life is cell.

In the simulation, when protein molecules were evenly distributed on both sides of the membrane, was the solution isotonic, hypertonic, or hypotonic? Which direction was water flowing?

Answers

Answer:

1. Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.

2.

a. A semipermeable membrane allows some substances to pass through it.

b. The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.

3.

a. The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.

b. In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.

4.

a. The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.

b. In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.

5.

a. A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.

b. If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.

Explanation:

When protein molecules were evenly distributed on both sides of the membrane, the solution is isotonic.

In isotonic solution the concentration of  solutes on side remain same .There is no net gain or less of water in isotonic solution.

What will be the direction of water flow in isotonic solution?The water will flow freely  across the cell membrane without any change in the concentration of solutes.In isotonic solution the cell neither shrink nor swell because the water concentration will remain same.

Which of the following statements about cellular respiration is true? Group of answer choices In glycolysis, NAD+ is oxidized to form NADH. In the electron transport chain, NAD+ is oxidized to form NADH. In the electron transport chain, NAD+ is reduced to form NADH. In glycolysis, NAD+ is reduced to form NADH.

Answers

Answer:

In glycolysis, NAD+ is reduced to form NADH.

Explanation:

NAD+ gains an hydrogen electron in the glycolysis pathway which translates to a reduction and not an oxidation.

There is also a subsequent oxidation that takes place in the electron transport chain system.

This facts makes NAD+ as being reduced to NADH in glycolysis as the right fans best option to choose from.
