Answer:
B/D
Explanation:
it's either B because if a flat Wing male can't find a female that likes is tripping is it helpful to go around and wander and maybe he'll find a mate
or it's D because there's a lot of crickets out in the open and where everybody else is his group gets everywhere so what I'm saying is it help to wander cuz that reduces the competition there so many male chirping that it's kind of hard to find a certain one that will attract the female
That's a hard question.i had the same question and didn't get an answer
Answer: The lac operon is an inducible operon that is activated in the presence of lactose.
An operon is a unit of genes which are controlled by the single promoter and operator sequence. It consists of a regulatory gene, promoter, operator, and structural genes.
Lac (lactose) operon consists of three structural genes namely lacZ, lacY, and lacA. These genes are transcribed and translated to produce specific enzymes used for lactose metabolism.
It is called as inducible operon because lactose acts like an inducer as its presence induces the transcription process. The lactose is first converted into allolactose which then binds to repressor (synthesized by regulatory gene). In this way, it makes the repressor inactive and therefore allows the transcription of structural genes.
Heterotrophs help in maintaining a balance in the ecosystem by providing organic compounds for autotrophs. Certain heterotrophs such as fungi help in reducing decomposed plant and animal material. This recycling activity is important in reducing waste in the environment.
