Answer:
B. Meiosis I
Explanation:
In meiosis I, it starts with a diploid cell with a homologous chromosome pair. The crossing of genetic material between chromosome pairs also occurs in this stage. The alleles containing the same trait would get separated so a new combination of alleles can be produced.
Mechanisms of gene regulation include: Regulating the rate of transcription. ... Regulating the processing of RNA molecules, including alternative splicing to produce more than one protein product from a single gene. Regulating the stability of mRNA molecules.
Answer:
E. Chromatium, Thiospirillum, Thidictyon
Explanation:
- There are some bacteria which are capable of conducting photosynthesis without producing oxygen in the process and bacteriochlorophyll is the main structural unit of the photosynthetic component of such bacteria.
- Purple a green sulfur bacteria are the ones that contain bacteriochlorophyll.
- bacteriochlorophyll's function is the same as that of chlorophyll in plants.
- <em>Chromatium, Thiospirillum, Thidictyon </em>are the bacteria that contain bacteriochlorophyll.
I'm sorry but I really can't answer that
Good luck though
