A: In a food web, the population of producers affects the population of consumers.
If there's less vegetation, the producers, there's less for deer to eat so the population decreases, and consequently because there are less deer for the wolves to eat, the wolf population decreases as well.
Answer:
b. Allolactose binds to the repressor protein.
Explanation:
Allolactose is an inducer of the lac operon. It binds to the repressor protein and brings about some changes in its confirmation to render it unable to bind to the operator sequence. RNA polymerase enzyme is allowed to transcribe the lac operon. The operator sequence is a binding site for repressor protein and is present near the promoter. When lactose is not present in the medium, repressor protein binds to the operator sequence and does not allow the RNA polymerase to transcribe lac operon.
Answer:
I think B
Explanation:
Because it is not a physical weathering example, it is not based on the weather it is based on a growing plant.
The probability of having a green seed and a round seed is 1/8th
Answer: B) interference with new viral replication in preexisting cases
Explanation:
The herpes viruses are very important enveloped DNA viruses that cause disease in all vertebrate species and in some invertebrates such as oysters. Some of the human ones are herpes simplex (HSV) I and II, causing facial and genital lesions, and the varicella-zoster (VSV), causing chicken pox and shingles. Each of these three actively infect nervous tissue. Primary infections are fairly mild, but the virus is not then cleared from the host; rather, viral genomes are maintained in cells in a latent phase. The virus can then reactivate, replicate again, and be infectious to others.
If scientists are trying to use what they know about HSV to devise a means of protecting other people from being infected, which of the following would have the best chance of lowering the number of new cases of infection?
B) interference with new viral replication in preexisting cases.
