Answer:
A) Divergent evolution because all of the species have similar structures during the first stage of development.
Explanation:
Answer:
The statement is true
Explanation:
Hematopoietic stem cells give rise to myeloid progenitor and lymphoid progenitor and these two progenitors give rise to many immune cells. Dendritic cells are produced by both the progenitors and macrophages are produced by myeloid progenitor.
Both macrophages and dendritic cells are phagocytes. In phagocytosis, the foreing particles are injected by these phagocytes and they are destryoyed by the action of digestive enzymes present in these phagocytic cells.
Macrophages are present in tissue and if they are present in blood they are called monocytes. Therefore the statement is true.
B) They maintain balance in the cell.
That mix of hydrophobic and hydrophilic, in other words, the mix of repelling and attraction maintains the aqueous balance in a cell and it's exterior.
