Answer:
Population size of elk increased while the population of aspen tree declined.
Explanation:
As per question, removal of wolves from the system would result in increased elk population due to absence of its predator (wolves). The increased elk population would extensively feed on shrubs and trees like aspen and cottonwood trees. This would cause decline in population size of these shrubs and trees.
Answer:
Option D is correct.
Explanation:
Option a) given in the option that if promoter is altered it will inhibit transcription which is the process by which information present in DNA converted to mRNA which require RNA polymerase which bind to promoter site so if promoter is altered RNA polymerase will not bind so transcription will be inhibited but above question is asking about inhibition of translation due to binding of miRNA-delta molecule to Q mRNA so this option can be eliminated.
Option b if miRNA binding site sequence is altered miRNA molecule will not be able to bind to Q mRNA so translation will not be inhibited hence option b is incorrect
Option c translation of Q mRNA is inhibited when miRNA - delta is present not absent
So option c can be eliminated
Option d if miRNA binding sequence is altered miRNA molecule if present will not bind to Q mRNA hence translation of Q mRNA will occur & not inhibited
Hence option d is correct
The Sun dumps a lot of thermal energy by sunlight into the atmosphere, and especially into the oceans. Basically, currents arise as warm equatorial waters move to the NORTH carrying heat, and as part of this flow, the cold polar waters go south and there get heated. Then, the SUN is like an engine which drives ocean currents.
Hope that helps
