True because, more variation increases the species fitness, the ability to survive and reproduce. Allowing the organism to pass on their beneficial traits (advantageous traits), to their offspring.
Answer:
The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.
Explanation:
Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.
With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.
Answer:
The zebra mussels also outcompete the natives for food and space, and because of their fast reproduction can quickly overwhelm a water system.
Explanation:
The feeding habits of zebra mussels can also have a drastic impact on an infested lake. Zebra mussels are filter feeders that siphon particles of plankton from the water.
