Answer: C. Homologous chromosomes are separated in meiosis but not in mitosis.
Explanation: There are two main types of division that take place in eukaryotic cells, mitosis, and meiosis. Mitosis is the type of division that is used for growth, repair, and replacement of tissues. Therefore it is not necessary that the cells have different chromosome numbers or are varied genetically in the daughter cells in the case of mitosis.
Meiosis is the division that takes place to form the gametes for sexual reproduction. It is important in the first stages of meiosis I, to introduce variation and to halve the chromosome number.
Chromosomes numbers are halved (from 46 to 23) during meiosis I because the gametes (sperm and egg) come together and fuse during fertilization to form a zygote. When this fusion occurs (23 from the zygote and 23 from the egg), the chromosome number needs to be returned to that of the parent cell (46).
<h2>
Genetic variation is introduced during synapsis which only occurs in meiosis, not mitosis. Homologs exchange genetic information during crossing over of synapsis. Entire chromosomes also separate during meiosis I.
</h2>
At the end of meiosis, four genetically unique cells are produced with half the number of chromosomes as the parent cell (23 cromosomes) . After the process of mitosis is completed, two cells genetically identical to each pther are produced and have the same number of chromosomes as the parent cell (46 cromosomes).
Genetic variation is actually important because of changing environmental conditions.
If you're talking about one storm for each, then acid rain would erode more Because acid breaks down material much easier then water.

Venus is the answer. That planet has a dense atmosphere of CO2, which has produced a runaway greenhouse effect.
Answer:
There made up of multiple cells
Explanation:
Given the information available to us through the image provided, we can see that the rate at which Claire's small intestine breaks down the protein, lipids, and carbohydrates is lower than that of a healthy dog.
<h3>What does the graph tell us?</h3>
- The graph shows Claire's enzyme activity using a yellow line.
- The red line shows us a healthy dog.
- In each graph, the yellow line is lower than the red, indicating that Claire's enzyme activity is lower than normal.
Therefore, given that the graphs represent claire's ability to break down these substances using a yellow line that appears to be lower than the red line representing a healthy dog through each substance, we can confirm that Claire breaks them down at reduced rates.
