C) Hospital systems provide a mechanism for extreme selection pressure with sterile technique and heavy use of antibiotics.
D) Staphylococcus aureus can transmit genetic components containing the methicillin resistance to offspring and other members of the population.
I cant fully answer, but i know that the phospholipids being amphipathic in nature is important and plays a role in fluidity.
Answer:
the correct answer is - (C) <u>if it is a recessive allele - carriers will have that allele in their genome but not express the lethal form of the gene</u>
Explanation:
for example chicken pox stays in your body your entire life after you have it once, and comes back when your'e old, in the form of shingles.
Answer: The options are missing from the question.
The options are;
1) Microevolution can lead to macroevolution.
2) Macroevolution can lead to microevolution.
3) Genetic drift cannot affect microevolution.
4) Natural selection only acts on macroevolution.
The correct answer to the question is option 1
MICROEVOLUTION CAN LEAD TO MACROEVOLUTION.
Explanation:
When we talk about microevolution,we are talking about the formation of species via the process of speciation. This formation of species via speciation is made possible by natural selection,a process whereby organisms that are better adapted to their own environment survive in their environment as well as bring about) reproduce new one/species that are similar to themselves. In this process, changes occur with traits but they do so with time. On the other hand, when we talk about macroevolution,we are referring to when major group of organisms form from those groups of species of organisms that are different in a distinct way/manner.
In macroevolution large number of changes occur in the characteristics of the living organisms present,for example, the evolution of entirely new species from the ones that are previously existing. Therefore,we would say that macroevolution is the result of many microevolution processes.
A good example of this is the development of mammals from non-mammalian species or evolution of whales from terrestrial mammals.
