The big idea to remember is that mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same. You get the idea.
So it is the very last stage!
Mutualism, The question is asking us to choose the correct symbiotic relationship.
There are THREE types of Symbiosis.
SYMBIOSIS is a relationship between two organisms.
I'll give you a quick run-through of each one.
1. MUTUALISM is where both organisms benefit, from one another.
2. COMMENSALISM is where one organism benefits, and the other is totally unaffected.
3. PARASITISM is where one organism benefits, while the other is harmed.
This is an example of an Epigenetic effect.
Explanation:
It is the study of heritable changes in the expression of genes, that are not involved in the changes present in DNA sequence. It is regular and naturally occurred, sometimes factors are responsible like age, lifestyle and disease state.
At times it leads to more damaging effect that can cause cancer. So this is also related to various fatal disease. During adulthood epigenetic effect remains stable. It does not occur in mother womb, but during the lifespan. This epigenetic effect can be reversed.
