The eruption of Mount Saint Helens has proved to have dramatically change the abiotic and biotic factors of its environment. As what was shown in the image just 24 years from its eruption, we can already observe that animal life began to populate the region due to its sufficient vegetation.

What is Mitosis?
"Mitosis is the cycle that eukaryotic cells go through in order to divide. During mitosis, a cell duplicates its DNA and divides into two genetically identical cells.
Mitosis and cytokinesis are part of the mitotic phase of the cell cycle, which make up about 20 percent of the entire lifecycle of a cell. The end result of mitosis is two completely separate cells with equal and similar cellular components. "
"Meiosis is the special cell division cycle for gamete cells, or sex cells. Chromosomes carry the genetic code for an organism, and come in pairs. In asexual reproduction, a cell will just divide itself to create two new cells. In sexual reproduction, the parent provides one set of each chromosome, or half the genetic code for an organism. When the two parent donor gametes – typically an egg and sperm – meet in fertilization, they provide the offspring with the full set of necessary chromosomes. For example, humans require 46 chromosomes, or 23 pairs. An egg or sperm will have just 23 chromosomes, or one half of the pair. This makes gamete cell division more complex than ordinary cell division. Within this cycle, the number of chromosomes is halved, typically going from a diploid (two sets) to haploid (one set) cell. It also includes a step where the chromosomes cross, allowing for more genetic diversity in reproduction."

Hopefully that helped, have a wonderful day :)
Answer:
You prepare a slide with a thin slice of onion root tip. You see the following view in a light microscope. Identify the stage of mitosis for each of the outlined cell.
Explanation:
A: Metaphase
B: Anaphase
C: Telophase
D: Prophase
46 chromosome in 1 human gets 23 from each parent
