I need help with a Philosophy question. All explanations and answers will be used to help me learn.

answer these question:

NOTE: EACH QUESTION HAS TO BE AT LEAST HALF a PAGE.

1.Using at least one physiological example, explain the concept of homeostasis.

2.Explain and provide examples of specificity, competition and saturation in proteins.

3.Explain the concepts of specificity, competition, and saturation as they relate to enzymes.

4.Explain the fluid-mosaic model of the cell membrane.

5.Compare osmolarity and tonicity.

6.Compare diffusion, facilitated diffusion and active transport.

7.Explain why cells need both channel and carrier proteins.

8.Explain the concepts of specificity, competition, and saturation as they relate to carrier-mediated transport.

9.Explain how the development of our understanding of cell-to-cell communication supports our core concept that physiology is a science.

10.Compare the general sequence of events that follow lipophilic and lipophobic binding to receptors.

11.Compare two forms of long-distance and three forms of local communication. 12.Explain the concepts of specificity, competition, and saturation as they relate to cell signaling.
