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.

<span>The glacial sediment is known as glacial till.
Glacial till is derived from entrainment and erosion of material by the moving ice of the glacier.
It is being deposited a distance down -ice to form ground moraines, medical, lateral, and terminal. Glacial till is divided into primary deposits which are rewarded by fluvial transport.
The large rock which is transported by a glacier is called moraines. Moraines are formed from debris which is previously carried along by a glacier and consists of rounded particles which range in size from the large boulders.
Moraines are of different types, for example, ground moraines, lateral moraines, and recessional moraine.</span>
Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases. Various events can contribute to change in the density of seawater. Salinity can decrease from the melting of polar ice or increase from the freezing of polar ice.
