The answer should be D. Electrons
Answer:
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.
Explanation:
A) agonist is the correct answer
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.

Explanation:
During meiosis, sister chromosomes of a homologous pair separate into different cells during gamete formation . This mainly occurs in Metaphase I of meiosis where the homologous chromosomes line up the metaphase plate in their sets. Each chromosomes of a pair are then pulled to different poles of the cells separating them. Each of these chromosomes carries a set of alleles of a gene. Each cell/gamete, therefore, carried half the set of alleles of all genes compared to autosomal cells. There many combinations of these sets that can occur depending on the number of chromosomes the organism has.
These cells when combined with that of another parent during fertilization, form a zygote that grows and develops into a mature organism. The offspring will bear the characteristics of both parents because it inherits half a set of chromosomes from both parents.
