<span>Epithelial cells in the stomach require the use of coupled transport to make gastric acid. They use hydrogen potassium ATPase, which is an electroneutral pump, and exchanges potassium for hydronium in order to produce the gastric acid.</span>
Answer:
C
Explanation:
Because the newts with this mutation have faster reflexes, they are able to evade predators much better than the normal newts. This increases their chances of survival hence are more likely to reach reproductive age than the normal newts. Therefore they have a higher probability of passing their genes to the next generations. With each generation, newts with the mutated gene will increase.
Griffith's experiment worked with two types of pneumococcal bacteria (a rough type and a smooth type) and identified that a "transforming principle" could transform them from one type to another.
At first, bacteriologists suspected the transforming factor was a protein. The "transforming principle" could be precipitated with alcohol, which showed that it was not a carbohydrate. But Avery and McCarty observed that proteases (enzymes that degrade proteins) did not destroy the transforming principle. Neither did lipases (enzymes that digest lipids). Later they found that the transforming substance was made of nucleic acids but ribonuclease (which digests RNA) did not inactivate the substance. By this method, they were able to obtain small amounts of highly purified transforming principle, which they could then analyze through other tests to determine its identity, which corresponded to DNA.
Answer:
I think c
Explanation:
active transport uses energy from ATP which is not found in the nucleus. so we know it uses energy which is not it's own and ATP is not apart of the nucleus so that leaves c
