<span>The concept of cell signaling is a communication network that is responsible for majority of the cellular activities. It is important that if the cell is deprived of this ability it will soon die. Since a cell is able to correctly interact with it's environment and perceive it, they are able to repair tissues, develop, and become immune to normal tissue homeostasis.

Answer:
ATP synthase utilizes energy of the proton gradient to attach phosphate groups to ADP.
Explanation:
ATP synthase is an enzyme that requires some form of energy to form energy storing molecule ATP, from adenosine diphosphate (ADP) and inorganic phosphate (Pi). Because of that, ATP synthesis is coupled with cellular respiration and electrochemical gradient created by the difference in proton (H+) concentration across the mitochondrial membrane during the transport of electrons through the electron transport chain. In plants, proton gradient is formed in chloroplast, in the thylakoid lumen through the thylakoid membrane.
From the vas deferens , the sperms move through the prostate gland to acquire the alkaline media to neutralize the vaginal environment ,then the sperms move to the urethra
After pollination and fertilization following changes occur in a flower: (i) The petals, stamens, style and stigma of the flower fall off. (ii) Sepals dry up and hold the ovary. (iii) The ovules confined in the ovary develop into seeds.
Answer: decreases with decreased
Explanation:
Altitude is height above sea level.
The density of air decreases with height.
At higher altitudes, there is less air pushing down from above, and gravity is weaker farther from Earth's center.
So at higher altitudes, air molecules can spread out more, and air density decreases
