Chromosomes have hereditary function that are capable of self-duplication and they have thread-like structures seen inside the nucleus of plant and animal. In plants, they go through a cycle called alteration of generation that has multicellular stages. One is sporophyte that is a diploid, and the other is gametophyte with a haploid.
Moreover, spores are produce through meiosis so it go through a process of chromosome reduction in order to create a haploid spores. While, gametes undergo mitosis and the structure is already a haploid, which means that the number of chromosomes will not change in order to produce haploid. In this case, the plant have both spores and gametes and the similarities is that, they are both singles celled and a haploid. Therefore, the number of the chromosome in the gametophyte generation is also 32.
Answer: the correct answer is (B) Whether others of the closely related group of plants also produce histidine in large quantities
Explanation:
This is a CAUSAL argument.
In a causal argument, A and B are observed together, and the CR concludes that A CAUSES B.
Premise = A and B are observed together:
A cultivated herb produces histidine and is able to grow in metal rich soils.
Conclusion = A causes B:
Histidine CAUSES the herb to be able to grow in metal rich soils.
One way to strengthen the conclusion that A causes B is give ANOTHER SUPPORTING EXAMPLE that links A to B.
NADH and FADH2 are used in the next step of the aerobic respiration(electron transport chain) for their electrons, the energy they store in the electrons to be precise
"REPRODUCTIVE ISOLATION" needs to occur for speciation to happen.....
