The given question is not about true/false. The correct question is:
Question: Sheath of schwann cell containing cytoplasm and nucleus that encloses myelin.......
Answer:
Neurolemma
Explanation:
Schwann cells are one of the two types of neuroglia that produce myelin sheaths. Schwann cells produce the myelin sheath in the peripheral nervous system. These cells produce the myelin sheaths around axons during fetal development. During the process, several layers of the glial plasma membrane surround the axon. The Schwann cell’s cytoplasm and nucleus form the outermost layer. On the other hand, the inner part is composed of multiple layers of Schwann cell membrane and is called the myelin sheath. The outer nucleated cytoplasmic layer of the Schwann cell that encloses the myelin sheath is called the neurolemma.
Answer:
True
Explanation:
Normal flora are microorganisms that are regarded as resident organisms, which can be found on or in an individual and do not cause any disease.
the transient flora refers to microorganisms that are found on the skin or the hands which are there through direct contact with person or object, and are easily removed by routine hand hygiene. Example is Norovirus that can cause stomach flu.
Opportunistic pathogens are microorganisms such as the bacteria and virus, which can only cause infection when the immune system is down. This means that , these organisms can not cause any infection as long as the immune system is ok.
In this case, the normal and transient flora like Norovirus can only cause infection when the immune system is down. That is why they are regarded as opportunistic pathogens.
In human genetics, this is type of inheritance is called multiple alleles.There are more than 2 alleles in the population and there are 4 possible phenotypes for this type of inheritance. Each blood type refers to a specific antigen, most useful in blood transfusions.
