Question

You observe two female fish of the same species breeding one female lays 100 eggs and the other female lay 1000 eggs. Which one of the following most likely given the trade-offs? The female who lays 1000 eggs breeds more often than the one who lays 100 eggs. The female laying 1000 eggs has larger eggs than the female laying 100 eggs. The female who lays 100 eggs breeds more often than the one who lays 1000 eggs. The female laying 1000 eggs lives longer than the one laying 100 eggs. Some viruses are able to avoid detection by the host, most likely due to the presence of reverse transcriptase a membranous envelope a single-stranded RNA genome capsid proteins Natural selection that kills off all extreme variants in a population is called __________ selection. stabilizing directional balancing disruptive sexual

Explanation / Answer

2. Some viruses avoid detection by host machinary that is due to presense of capsid proteins. it acts as a shield and protects its genome( whatever DNA or RNA) from degradation by host enzymes.

NOTE: Reverse transcriptase is an enzyme which make complimentary DNA from viral RNA and that DNA is further incorporated into the host DNA. Thus viruses reproduce.

3. Natural selection that kills all the extreme variants in a population- It is stabilizing selection. In this type of natural selection extreme varietiesfrom both ends of the frequency distribution are eliminated that means this types favours intermediate type.Stabilizing selection acts to keep population well adapted to its environment.

Variants are removed means homozygosity is favoured.
