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.
When a stem cell divides, each new cell can either stay a stem cell or become a specialized cell, such as a muscle cell, a red blood cell, or a brain cell.

Answer:
b. where movement occurs through arm-over-arm swinging.
Explanation:
Brachiation is a form of locomotion observed in some species of animal that are adapted to arboreal (tree living) life.
<em>This type of locomotion involves the swinging of arms and the suspension of the body to move from trees to trees.</em>
Animals that exhibit brachiation usually have modified body structure with long forelimbs/hook-like fingers and a highly mobile shoulder joints. Examples of such animals include gibbons and siamangs.
