A population cycle in zoology is a phenomenon where populations rise and fall over a predictable period of time. There are some species where population numbers have reasonably predictable patterns of change although the full reasons for population
To conserve energy, the genes in E coli are ONLY ACTIVE WHEN NEEDED.
Gene regulation refers to the turning on and off of genes. Gene regulation makes it possible for cells to produce specific proteins only when they are needed. In E coli for instance, the necessary enzyme for the metabolism of lactose is only turned on only when lactose is present, this is done as mean of preserving energy.
Explain how the reactions of “the bloodless ghouls” to Orpheus’s song in paragraph 3 are important to the overall theme of the story. Cite evidence from the story in your response.
Answer:
<em>S. carcini</em> is a parasitic barnacle species
Explanation:
Parasitism: In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness. These interactions are mostly about nutrition, although there might be other benefits too. Some parasite species might coexist with their host, while some others might get them ill to the point of causing death. Parasitic attacks might be very nocive, and even though they are not lethal in a short period of time, they might slowly kill the host.
Parasitic species consume part of the host, but not the whole body. They develop an intimate relationship with their host.
- The Host increases the fitness of the parasite species
- The parasitic species decreases the fitness of the host.
By taking the nutrients from the green crab's blood and sterilizing it, the barnacle causes a decrease in the fitness of the crab. The crab becomes weaker and its survival chances decrease, and they have no opportunity to reproduce. Meanwhile, the barnacle gets stronger and reproduces normally.
They are composed of proteins. I cannot see the options but hopefully that answer is in one of them
