How are cells affected by the movement of water?

Answers

Answer 1

Answer:

Cells are affected by the movement of water through osmosis. Osmosis is a natural phenomenon in which molecules move from lower concentration to higher concentration. This movement depending on the solution type of the environment can either shrink or burst or oversaturate a cell

A student poses the question: How does the presence of dissolved salt affect the freezing point of water? To answer this question, the student set up two conditions. In the first condition, the student added salt to water in a container and referred to this condition as the variable. In the second condition, the student did not add any salt to water in a second container and referred to this condition as the control. The student took both containers and attempted to freeze the water at various temperatures to assess the freezing point. Would this be a valid experiment? A. Yes, because there is more than one variable. B. Yes, because there is one variable and a control C. No, because there is not more than one variable D. No because there is only one variable and a control

A human skin cell contains 46 chromosomes. Afrog sperm cell contains 12 chromosomes.
Which pair of numbers shows the chromosome
number of a normal gamete from each of these
species?
(1) human 46; frog 12 (3) human 23; frog 24
(2) human 46; frog 24 (4) human 23; frog 12

Answers

The number of chromosomes for the gamete of each of the species would be half of that of their vegetative cells.

Haploid cells

Haploid cells contain half (n) the number of chromosomes of diploid cells (2n)

Gametes are generally haploid in nature.

The human skin cells are vegetative cells (2n), thus a gamete of humans would have 23 or (46/2) chromosomes.

The frog sperm cell is a gamete cell. Hence, the chromosome number remains 12.

In other words, human gametes will have 23 chromosomes while frog gametes will have 12.

Answer: Human 23; frog 12

Explanation: Skin cells are somatic cells, that means the they build the body and divide by mitosis. This kind of cells have genetic charge 2n or twice of the gamete's chromosomes, so a human gamete (sperm or ovum) has 23 chromosomes (46/2 = 23).

Frog sperm cell is a gamete so it has the number of chromosomes for this type of cell which is 12
