Based on the nature of proton gradient, (A) is false, but (R) is true.
<h3>What is a proton gradient?</h3>
A proton gradient is a gradient that exists due to difference in proton concentration between the inner and outer mitochondrial matrix.
An assertion is a statement or claim stating a given position.
- Assertion (A): A proton gradient cannot be established in the mitochondria.
- Reason (R): Hydrogen molecules are pumped out of an internal space (the matrix) in the mitochondria.
The assertion, A, is false because a proton gradient is established in the mitochondria due to the function of the proton pump which pumps out protons from the inner mitochondrial matrix to the outer membrane.
The reason, R is true as hydrogen molecules are pumped out of an internal space (the matrix) in the mitochondria by the proton pump.
Therefore, (A) is false, but (R) is true.

Answer:
They are both hormones that regulate blood-sugar levels
Explanation:
Insulin is a hormone that controls the blood glucose level. It released in the blood stream when the glucose level increases after eating food. It is produces by pancreas, insulin helps the glucose to enter the body's cells where it can either be stored for future use or can be used for energy.
Glcogen is produced by alpha cells of pancreas, it is a peptide hormone. Its main function is to raise the concentration of fatty acids and glucose in the bloodstream. It is one of the main catabolic hormone of the body
As per the above mentioned statements, the option 'They are both hormones that regulate blood-sugar levels' is the correct answer.
<span>the statement that is most likely true about the plant is : the plant has two identical alleles for the gene that codes for the trait.
For example, if a plant has a recessive tt allele for short, the chance of its offspring to be born short is really small. Because if it paired with dominant tall Allele T, the offspring will have the characteristic of tall plant</span>
