Answer:
When the cell has 0% sucrose I expect the cell to stay the same.
Explanation:
First of all, this question should not be confused for the statement "When the "cell" has 0% sucrose, did you expect the cell to have gained water, lost water, or stay the same. In this case, the correct answer would have been; gained water.
But, in this question, we are asked what happens to the cells at 0% sucrose concentration. At 0% (no solute) concentration, there is no net movement of water or solute into or out of the cell, because the cell is isotonic to the external environment (distilled water). Osmosis, a special kind of diffusion, is the movement of water, from areas of lower solute concentration to area of higher solute concentration, or from areas of higher water concentration to areas of lower water concentration through a semi-permeable membrane. If the water moves into the cells (hypertonic cells), then the cell gains water and increases in size, but if the cell loses water (hypotonic cell), then it reduces in size

During meiosis but not during mitosis, which of the following is true? __.
A haploid gametes are produced that are identical in their allelic composition
B the cytoplasm divides
C chromosomes line up in the center of the cell during metaphase
D genetic variation among the daughter cells is increased
E two identical daughter cells are produced
Answer:
D. genetic variation among the daughter cells is increased
Explanation:
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. Meiosis occurs in germ cells, as a result; genetic variation among the daughter cells is increased. These cells (germ cells) are our sex cells – sperm in males, eggs in females.
In meiosis, the haploid gametes that are produced are not identical in their allelic composition.
In prophase 1, the chromosome pair up.
During metaphase, The chromosome pairs line up next to each other along the center (equator) of the cell.
