The best description of predictable development of plant structure in an area over time is primary succession. The correct option is a.
<h3>What is succession?</h3>
Changes in the physical environment and the population of the species cause succession. There are two types of succession: primary and secondary succession.
Nudation, invasion, competition and coaction, reaction, and stabilization are the five stages of ecological succession. Autogenic succession is derived by biotic factor in an ecosystem.
Thus, the correct option is a. primary succession.

Answer:
Methanesulfinic acid (MSIA) is an important intermediate in the oxidation of dimethyl sulfide (DMS) in the marine boundary layer. The oxidation of MSIA by ozone in the gas phase to form methanesulfonic acid (MSA) was investigated using theoretical calculations in this paper. Three pathways can be found for the reaction of MSIA with ozone. The highest energy barrier is 13.02 kcal mol−1 in the most favorable pathway. By comparing the reaction rate of MSIA + O3 with that of MSIA + OH, it can be concluded that the oxidation of MSIA by O3 to form MSA is of minor significance relative to its oxidation by OH radical in the gas phase. This study can provide some information for the theoretical and experimental studies in the significantly heterogeneous and aqueous-phase oxidation of MSIA by O3.
The mystery food sample did not test positive for protein using the Biuret indicator, so the sample can not be tofu, which is what Zack ate.

Explanation:
A) First of all, it must be considered that HIV has a RNA genome.
The reverse transcriptase is a viral enzyme able to convert a RNA molecule (in this case the RNA would be the viral genome) to DNA. This process is important for two reasons:
* The DNA molecule is more stable than RNA --> Therefore, there is a higher likely that the molecule wouldn't be degradated by the host.
* The viral genome made of DNA will be integrated into the host genome --> To do so, it requires to be DNA instead of RNA
B) The inibitor is able to target the Reverse Transcriptase --> So, the likehood of converting RNA to DNA is lower. In this case, the single RNA molecule is less stable than the DNA and the host can degradate it more easily.
C) In general, the viral will not survive the treatment and, hence, the patient will not suffer from the viral infection
