During diffusion, molecules move...
- A.
From areas of low concentration to areas of high concentration.
- B.
From areas of high concentration to areas of low concentration.
- C.
By active transport.
- D.
Only through selectively permeable membranes.
Correct Answer
B. From areas of high concentration to areas of low concentration.Explanation
During diffusion, molecules move from areas of high concentration to areas of low concentration. This is because diffusion is a passive process that occurs due to the random movement of molecules. Molecules naturally move from an area where they are more concentrated to an area where they are less concentrated in order to achieve equilibrium. This movement continues until the concentration of molecules is equal throughout the entire system. Therefore, the correct answer is from areas of high concentration to areas of low concentration.Rate this question:

What happens to an animal cell placed in a hypotonic environment?
- A.
The cell will shrink due to the movement of water out of the cell.
- B.
The cell will remain the same size because the movement of water into the cell will equal the movement of water out of the cell.
- C.
The cell will swell dut to the movement of water into the cell.
- D.
The cell will swell dut to the movement of solute into the cell.
Correct Answer
C. The cell will swell dut to the movement of water into the cell.Explanation
When an animal cell is placed in a hypotonic environment, the concentration of solutes outside the cell is lower than inside the cell. As a result, water will move into the cell through osmosis, causing it to swell or expand. This is because water moves from an area of lower solute concentration (outside the cell) to an area of higher solute concentration (inside the cell) in an attempt to equalize the concentration on both sides. Therefore, the correct answer is that the cell will swell due to the movement of water into the cell.Rate this question:

Correct Answer
C. 4Explanation
In meiosis, a type of cell division that occurs in sexually reproducing organisms, four cells are produced. This is because meiosis involves two rounds of cell division, known as meiosis I and meiosis II. During meiosis I, the parent cell divides into two daughter cells, each containing half the number of chromosomes as the parent cell. Then, during meiosis II, each of these daughter cells further divides into two, resulting in a total of four cells. These four cells are genetically different from each other and have half the number of chromosomes as the parent cell.Rate this question:

- D.
Random pairing of sperm and egg
Correct Answer(s)
A. Genetic recombination
B. Crossing over
D. Random pairing of sperm and eggExplanation
Genetic recombination refers to the process of combining genetic material from two different sources, leading to the creation of new combinations of genes. Crossing over is a specific type of genetic recombination that occurs during meiosis, where genetic material is exchanged between homologous chromosomes, further increasing genetic diversity. Random pairing of sperm and egg during sexual reproduction also contributes to genetic diversity as each individual has a unique combination of genes inherited from their parents. Forming chromosomes from chromatin does not directly contribute to genetic diversity as it is a normal process that occurs during cell division.Rate this question:

- D.
To make sure that chromosomes are copied equally.
Correct Answer
C. To create as many cells as possibleExplanation
The main goal of meiosis is to create haploid cells, which have half the number of chromosomes as the parent cell. This is important for sexual reproduction, as it allows for the fusion of two haploid cells during fertilization to restore the diploid number of chromosomes in the offspring. Meiosis also ensures that chromosomes are copied equally, through processes such as crossing over and independent assortment. However, the goal of meiosis is not to make identical cells, as the process involves genetic recombination and variation. The goal is also not to create as many cells as possible, as meiosis typically results in the formation of four haploid cells.Rate this question:
