They are said to be “denser” than air. what happens is that light slows down when it passes from the less dense air into the denser glass of water. this slowing down the ray of light also causes the ray of light to change directions. it is the change in the speed of the light that causes refraction.
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.

Answer:
C) Water will move out of the cell.
Explanation:
In microbial growth experiments, when a bacterium is placed in a Petri dish with a solution that contains dissolved salt (NaCl) - a hypertonic solution -, the result will lead to the <u>dehydration and shrinking of the bacterial cell</u>.
This condition will eventually cause the rupture of the cell, resulting in the diffuse of H20 molecules from the plasma membrane, that is, the water moving out of the cell.
