Answer:
organism, organ system, organ, tissue, cell
Explanation:
As given in the graph, mutation in this gene causes a decline in the production of glucose as it obstruct the process of photosynthesis.
<h3>What is psaB gene?</h3>
P700, the primary electron donor of photosystem I (PSI), as well as the electron acceptors A0, A1, and FX, are bound by PsaA and PsaB.
As given in the graph, mutation in this gene causes a decline in the production of glucose as it obstruct the process of photosynthesis.
Thus, the plant with the mutated psaB gene was dying.

C is the answer. Due to the current state of the world economy; people, if left to their own devices, would fish as much as possible so they can sell their fish to make money. Current technology means we can catch as many fish as we want (trawlers etc.). The problem with this is that there is only a finite amount of fish in the sea. If we were to fish them without limits in place, we could cause them to go extinct.
Assuming dragon genetics follow the same rules as fruit flies, we would get the same possible genotype for all 16 offspring provided that the genes are not linked.
Considering dragon genetics, flame eyes (F) are dominant to blue eyes (f) and burbling (B) is dominant to whistling (b).
Now, a dihybrid cross between two homozygous blue-eyed, whistling dragons will yield 16 offspring all with the same possible genotype .i.e. homozygous blue-eyed, whistling type.
Morgan through experiments on fruit flies observed that when the two genes in a dihybrid cross were situated on the same chromosome, the proportion of parental gene combination were much higher than the non-parental type.
He attributed this due to the physical association or linkage of the two genes and coined the term 'linkage' to describe the physical association of genes on a chromosome. The term 'recombination' is to describe the generation of non-parental gene combination.

Molecules with similar shapes have similar biological effects, because shape (structure) dictates effects (functions).
