The correct answer is contractile vacuole.
The contractile vacuole is a water bubble present in the endoplasm of the amoeba. The role of the contractile vacuole is same as the role of the central vacuole in plants.
The contractile vacuole stores the water and the waste material of the cell, along with some mineral and other substance, so, they help in the maintenance of the osmolarity. In case, the walls of the contractile vacuole is damaged, the cell may burst out.
The answer is ultrafiltration. This is helped by the hydrostatic pressure and blood pressure in afferent renal arteriole. Molecules such as water, glucose, urea, sodium chloride, amino acids pass through the semipermeable membrane of the dense capillary network of the glomerulus to form glomerular filtrate. Some of these molecules are later reabsorbed in the renal tubules.
Answer: A. is a measure of energy
Explanation:
Heat is one of the easiest forms of energy that man can detect in your environment because we have the sensation of cold, hot, sweat, drink liquids when we feel hot, see the engine of a car heat up, take a bath of water heated by an electric shower or a boiler, etc.
Heat transfer occurs until the moment bodies reach the same temperature (thermal equilibrium). Heat is the energy transferred between a system and its surroundings because of the differences in temperatures.
C. exocytosis (I have to use 20 characters to respond and "answer it well". Exo means out/outside and exocytosis is an active transport system where a cell uses energy to transport material, like protein or waste, from inside a cell to the outside.)
I think observation and measurable.
