D) Atom... is the right option
The ribosomes that is synthesizing the protein is directly attached to the ER membrane
The specific volume will be different for various kinds of cells. The safe answer would be that the new cell will pretty much have the same volume as the one that it divided from. This is true for most eukaryotic cells unless other factors like epigenetics or mutations come into place.
One example of moments a cell would increase in volume is during hypertrophy. This simply means that the cell is increasing in size (compared to: hyperplasia -- which is an increase in number of the cells). Hypertrophy is definitely an increase in volume of the cell but this doesn't necessarily translate to cell division (i.e. just because the cell is big now, doesn't mean it will still be big when it divides).
Another moment of increasing volume of the cell and now also related to cell division would be during the two stages in the cell cycle (i.e., G1 and G2 phases). This is the growth phase of the cell preparing to divide. However when mitosis or division happens, the cells will normally end with the same volume as when it started.
This are safe generalizations referring to the human cells. It would help if a more specific kind of cell was given.
Answer:
Polygenic traits
Explanation:
Polygenic traits are traits that are controlled by more than one gene and the physical expression of these genes is significantly influenced by environmental conditions .Characteristics that show continuous variations are controlled by many genes.The genes that control them may be located near each other or even on separate chromosomes. They are often represented as a range of continuous variation because they are not discrete.
Answer:
Convergent Evolution.
Explanation:
When two different species that are very distantly related but have similar traits its Convergent Evolution due to environmental pressures.
