The answer could be positive 24 and 25. And negative 24 and 25 since a negative times a negative equals a positive
Answer:
CO2 and O2 are water-soluble molecules that diffuse freely across cell membranes.
Cells expend energy in the form of ATP hydrolysis so as to maintain ion concentrations that differ from those found outside the cell.
Explanation:
CO2 and O2 are highly soluble molecules in water due to their polarizability and their ability to react with water molecules and form new compounds. CO2 is 30 times more soluble in water than oxygen, which also has a high solubility. This ability allows these two molecules to diffuse freely across cell membranes.
Cells promote hydrolysis, that is, the breakdown of ATP molecules when they need to expend energy for any metabolic process, especially when they need to maintain a balance between ion concentrations inside and outside the cell. This is because ATP is a highly energetic molecule and its breakdown promotes energy for the cell to use in its activities.
Specific sections of DNA molecules in the chromosome are activated
Answer: Basically something that refers within the cell or humand body or it can be physical or chemical conditions maintained by other living systems Living organisms need to maintain homeostasis constantly in order to properly grow, work, and survive. In general, homeostasis is essential for normal cell function, and overall balance. ... Again, homeostasis plays a crucial role in maintaining a constant body temperature (37C/98.6F) for enzymes to do their jobs.
