Answer:

Cellular homeostasis involves maintaining a balance of several things that make a cell healthy. The cell membrne is a lipid bilyer that prevents that passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell.

Which of the following is UNLIKELY to affect bone remodeling?A. parathyroid B. hormone low blood C. Ca2+ concentrationD. mechani

larisa86 [58]

Answer:

E. glucagon

Explanation:

Bone remodeling is a natural process that takes place in the human body continuously. The process destructs the old and mature portion of the bones and replaces it with the formation of new bones.

The process of bone remodeling is controlled by the hormones and the mechanical stress the bone faces. The hormone which controls the process is the parathyroid hormone and the calcium which is required during the process of synthesis of bones. The factor which is not involved in the process is glucagon.

Thus, glucagon concentration does not affect bone remodeling.

11. Which is a density-dependent factor?

Sophie [7]

Answer:

Explained below:

Explanation:

Density-dependent factors are biological factors adopted by the population as a resource. The things can be like shelter, food, or different poor resources. Density-dependent factors affect fitful variations in the population as its density fluctuations. If the population is small, these portions typically support improved rates of birth and lower will be the death rates, empowering the population to increase and when the population is big and thick, these factors display that the birth rate is decreased and death rate became higher.
