I think the correct answer from the choices listed above the first option. In a polar covalent bond, the distribution of common electrons are <span>not shared evenly due to a greater positive charge from one atom’s nucleus. Hope this answers the question. Have a nice day.</span>
Answer:
Sulfur can also fall directly from the atmosphere in a process called fallout. Also, the weathering of sulfur-containing rocks releases sulfur into the soil. These rocks originate from ocean sediments that are moved to land by the geologic uplifting of ocean sediments.
Answer:
Transcription factors
Explanation:
This is because Eukaryotic gene expression is regulated by transcription factors and RNA processing, which occur in the nucleus, and during protein translation, in the cytoplasm.
Transcription in eukaryotic cells is controlled by proteins . These proteins then bind to some specific regulatory sequences and try to control the activity of RNA polymerase. The Gene expression is regulate by transcriptional regulatory proteins . Also ,the packaging of DNA into chromatin and methylatiin indicate levels of complexity to the control of eukaryotic gene expression.
Answer:
C
Explanation:
We can rule out B and A easily as to pretty clear facts. C and D are the only ones left. Genetic variation (D) is not going to take place as there is no specific need for DNA variation.
