The answer is B. This is called genetic shift. The pups with
advantageous traits are able to survive until the age of reproduction hence able
to pass their genes to the next generation. Few and fewer pups with disadvantageous
traits will get to reproduce hence the allelic frequencies of the shark population
will shift in favour of increased hunting efficiency.
Answer:
None of the answers is correct, because prokaryotic cell doesn't have nucleus
Explanation:
In eukaryotic cell, primary transcript is RNA synthesized via transcription in the nucleus. After processing it becomes mature mRNA. The processes of processining are addition of the 5' cap, 3'-polyadenylation, and alternative splicing (excision of introns). Because during the processing of RNA introns are removed the primary transcript is larger than the mRNA.
Answer:
Chlorophast allows plants to capture the energy of the sun.
<span>Through a process called cellular differentiation, during development cells have specific genes which are turned on and off depending on their job function. At any time, cells will only have small amounts of DNA being used, the rest of the DNA is turned off. For example, muscle cells will have genes turned on to produce myosin, muscle fibers. Skin cells will have genes turned on to produce melanin and reproduce every twenty minutes.</span>
