D. all of these, models show multiple things.
Answer:
The correct answer is - They have substances that counteract acids or bases to prevent the pH from changing
Explanation:
All living organisms including humans are water-based systems, which implies that they rely intensely upon liquid equilibria, particularly acid-base equilibria. Hence, all the acid-base and pH ideas we have talked about so far are critical to the chemistry of organic or biological systems.
This is particularly significant for enzyme, which are proteins that go about as catalysts for all major biological reactions. Most enzymes just work inside a specific pH range. Because all natural cycles are subject to pH, cells and creatures must keep up a particular and consistent pH so as to keep their compounds in the ideal condition of protonation they have specific substances that counteract the acid and base to maintain pH.
for instance:
The pH of the Cytoplasm is maintained by the phosphate ion
The pH of the blood is regulated by the bicarbonate ion
Answer:
She is at risk for future obesity
Explanation:
Answer: Option D
Explanation:
The embryonic induction can be defined as the critical part in formation of the other tissues and organs because one cells affects the development of the other cells.
In vertebrates the notochord arises from the dorsal organiser, in amphibian the organizer is a region of vertebrate gastrulae which is when transplanted into the ventral region of the host embryo stimulates the formation of second embryonic axis and neural tube in embryo.
This generation of second notochord in the an example of influence of one group of cell on other.
