Answer:
b. the interaction of food availability and predation intensity
Explanation:
The complete question is as follows:
What best explains snowshoe hare and lynx population cycles?
a. the seasonal trends in food availability
b. the interaction of food availability and predation intensity
c. natural variation in the number of lynxes born
d. the population density of snowshoe hares
- The population of snowshoe hare and lynx are closely linked to each other and this is because the primary food of lynx is the snowshoe hare.
- When the number of hares is more lynx eat more of hares and less of other food and when the number of hares is scarce, lynx eat alternate food.
- However, in the scarcity of hares, the other foods do not provide lynx with their nutritional needs and therefore, many of them leave their home grounds.
- Therefore, when the hare number declines lynx number also declines.
- The population cycle spans over 8-11 years.
- The number of hares decreases at the end of the cycle and so does the number of lynx.
- However, at the beginning when the number of the hare is more, they starve due to competition and are easily caught by the lynx and thus, the lynx population also increases.
Answer:
RNA interference would degrade the FLC mRNA and instigate flowering.
The RNA interference refers to a molecular process, which is used by the cells to prevent the expression of any specific gene, that is, by not continuing the process of translation of mRNA. This can be done with the assistance of micro-RNAs or siRNAs.
The function of the siRNA primarily relies upon its tendency of binding with RISC or RNA-induced silencing complex. Once it combines with RISC, the unwinding of the double-stranded RNA occurs and is succeeded by the cleavage of the sense strand. This is attained with the activity of endonucleases over it. The left antisense strand will mediate the RISC factor towards mRNA for preventing its transcription, and thus, silencing it.
