Phagocytes are the type of cells that 'devour' foreign cells in order to protect the body using phagocytosis.
Answer:
<em>Digested food is a source of potential energy</em>
Explanation:
When we digest food, the molecules of the food are broken down into smaller compounds. Chemical energy is released due to this process. Chemical energy can be used to form glucose and fat. These molecules store energy in them. When energy is required by the body, the glucose molecules can be converted into ATP and hence give energy. This energy can be used for various purposes such as it can be converted into mechanical energy for muscle movements.
Answer:
The word acidification can be misleading because a pH of 7.9 is still considered slightly alkaline. However, as the graphs in these three locations show, as CO2 rises, the pH drops, moving in the direction of the acidic end of the pH scale.
Explanation:
The variable “x” should go on the x-axis
Answer:
Simple cuboidal epithelia are found in areas that stretch.
Explanation:
The simple cuboidal epithelium consists of a single layer of cuboid cells with a centrally located nucleus. The cells of this epithelial tissue are mostly involved in secretion and absorption and therefore, are found in the lining of ovaries, lining of kidney tubules and gland ducts.
Transitional epithelium is like a stratified cuboidal epithelium when not stretched. Its cells become flatter when the tissue is stretched. It has multiple cell layers and elasticity and therefore, is found in the lining of the urinary bladder and parts of ureter and urethra to allow stretching of these organs.
