Answer:
Anti-diuretic hormone causes the kidneys to increases the permeability of the collecting ducts to water
.
Explanation:
The anti-diuretic hormones stimulates the process of water re-absorption by enhancing the water channels or aquaporins in the membranes of the kidney tubules. The solute free water are transferred through the channels in the tubular cells and back in the blood which then leads to decrease in the osmolarity of plasma with the increase in osmolarity of urine. The hormone is prepared in the hypothalamus of brain and stored in the pituitary glands. It reminds the kidney about the absorption of water, through which it maintains the balance of water in blood.
Specialized structures that perform cell functions are organelles.
What are cell organelles?
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
An organelle is a particular sort of cell structure. Organelles come in many different varieties. Vesicles are another name for organelles in a cell. They actually serve a purpose that is crucial since all of the processes in a cell must be compartmentalized. Therefore, a membrane is required to surround the processes inside a cell that produce diverse products. Organelles are therefore all membrane-bound in reality. They also distinguish between one function and another. So, for instance, the lysosome breaks down large molecules to make small molecules, while the mitochondrion produces energy by breaking down large molecules.
They must be divided up since the lysosome requires an acidic pH and the mitochondrion relies on all of its pathways, proteins, and enzymes to convert one chemical to another. Additionally, none of the functions would be created if those two substances were combined.

Answer:
Saliva lubricates and moistens these food particles
Explanation:
As teeth help to break down large pieces of food into lots of smaller pieces, saliva is released and mixes with the smaller food pieces. Saliva lubricates and moistens these food particles such that a ball-like mixture of food and saliva that is known as a bolus is formed, which can then be easily swallowed.
