B. I did a project on scorpions a few years back.
<span>Some primary differences between prokaryotic and eukaryotic cells is that prokaryotes do not have a an organized nucleus, nor do they have membrane-bound organelles. They also only possess a single chromosome. This makes them less complex than eurkaryotes, and thus prokaryotes perform binary fission instead of mitosis.</span>
Answer:
The complement system, also known as complement cascade, is a part of the immune system that enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.
Answer:
It allows daughter cells to have an exact copy of the parental DNA
Explanation:
In human mitosis, we are taking a cell with 46 chromosomes and we are creating two new daughter cells both with 46 chromosomes genetically identical to the parent cell. How do we do that? Through replication of the chromosome in S phase. Replicated chromosomes allow the chromatids to be separated during anaphase. If I have 46 chromosomes at the beginning of mitosis that are all duplicated that means I have 92 chromatids. If half of all the chromatids go into once cell and half into the other, then 96/2 would be 46 chromosomes. The trick is remembering that a chromosome can have either one or two chromatids. Duplicated ones have two chromatids but are still considered one chromosome. Therefore, by the end of mitosis I have 46 chromsomes in each cell, they are just unreplicated chromatids, which were allowed to be separated since they were duplicated in S phase.
