The biosphere is the sum of all ecosystems. Think about the ways water moves through the earth through the water cycle. It moves through water falls, through rain, it may stay in an aquifer, or it might evaporate and stay in the atmosphere humidity.
Answer:
An Oc mutation on the bacterial chromosome can affect the expression of structural genes on a F plasmid.
Explanation:
An Oc mutation is a mutation in which operator of an operon is constitutively active i.e. repressor fails to bind the operator which leads to unregulated gene expression.
An Oc mutation do not affect the expression of structural genes on F plasmid because <u>an operator is a cis regulatory element and therefore it can only affect the genes which are located on the same DNA</u>. F plasmid genes are located on the plasmid not on the main chromosome of the prokaryotes while tryptophan or lac operon system is in the main chromosome that is why an Oc mutation will not impact genes on plasmid.
Answer:
Explanation:
Key Points There are two kinds of neuroglia in the peripheral nervous system (PNS): Schwann cells and satellite cells. Schwann cells provide myelination to peripheral neurons. Satellite cells play an important role in modulating the PNS following injury and inflammation.
If a cell cannot function normally it will disturb homeostasis.
