Answer:
From the given observations we can say that there are 2 genes that are responsible for normal learning. It is also given that the dunce and rutabaga mutations are the mutations of 2 different genes.
Due to complementation which is a phenomenon of restoration of normal phenotype if mutants are crossed, it is found that the flies have normal learning behavior if both mutants are crossed.
Let's assume that the Drosophila having this learning effect and it is due to genes D and R where D is the normal gene and dd is the case of mutation that results in duncy phenotype. Similarly, Gene R is responsible for normal learning, and rr results in rutabaga phenotype.
Cross between ddRR (duncy) x DDrr (rutabaga)
Gametes - dR x Dr
F1 progeny - DdRr
Thus, in heterozygous cases, a single copy of both wild-type alleles D and R complement each other.

First let's take a look at the two squares close to the electron transport chain. As you can see, the two boxes are connected, which means there is some type of "conversion" occuring. Oxygen goes in and water comes out. (In other words, upper square = oxygen, lower square = water).
Now, the box that is far from the rest corresponds to the mithocondrial matrix of a mithocondrion, since we're talking about .
The two boxes connected to the ATP synthase are aso connected to each other, one going towards the ATP synthase and the other going out. Now, we just have to guide ourselves with logic. It's called "ATP synthase", which means the product will be ATP. So, ADP goes in and ATP comes out.

I think some ellimination would do good to answer this question. First of all, salmon contains a reasonable amount of B12 and iron and has high amounts of protein, of course. So options B., D. and E. are incorrect.
Nor salmon nor garlic butter contain fiber, so option A. is also incorrect.
Answer:
C.

The Krebs cycle, the electron transport chain and respiration (aerobic) are closely related, because in anaerobic respiration we obtain oxygen, which functions as an electron acceptor in the electron transport chain, which produces NAD+ that is later used in the Krebs cycle to produce NADH and FADH2 that are used as electron carryiers in the ETC.
Answer:
C.
