Answer:
The given blank can be filled with a venule.
Explanation:
A small blood vessel in the microcirculation, which connects the capillary beds to the veins is known as the venules. Various venules combine to form a vein. The walls of a venule are formed of three layers, that is, the inner endothelium formed of squamous endothelial cells, a middle layer of elastic and muscle tissue, and an external layer formed of fibrous connective tissue.
The size of a venule ranges from 8 to 100 micrometers in diameter and are produced when capillaries come in close association. A venule refers to a small blood vessel that permits the deoxygenated blood high in carbon dioxide and waste products to return from capillary beds to the bigger blood vessels known as veins.
Answer: The quantity of water in the beaker will reduce. The cell will increase size.
Explanation: There is difference in water concentration between the cell and the beaker, therefore water will move from the beaker into the cell causing the cell to expand and the quantity of water in the beaker to decrease. There will be movement of water molecules from an area of high water concentration (beaker) to an area of low water concentration (the cell) through a selectively permeable cell membrane. The aim of this is to create an equilibrium between the water concentration in the cell and that in the beaker.
b) in the blood include monocytes and neutrophils.
