Answer:
If the lac enzyme continues to be produced even in the absence of lactose, the cell will be expending energy unnecessarily and this will be a problem for the supply of energy for other metabolic processes.
If the lac operator gene is dragged to any stretch of DNA, that gene may provide an inadequate reading generating a mutation.
Explanation:
The lac operon is an essential molecule for the transport and metabolism of lactose in microorganisms. This molecule has a fundamental function in the life of these single-celled organisms and must be synthesized immediately when lactose is present in the organism, however, its synthesis must be stopped as soon as the lactose is metabolized, otherwise the cell can spend energy unnecessarily preventing others Metabolic processes take place, which is a big problem if you only have one cell.
In addition, if for some reason, the lac operon gene is dragged on the DNA strand, an incorrect reading of the DNA bases can occur, which can cause mutations.
What attachment? I don’t see any attachment?
The possible answers are :
A. it makes up the outer layer of the brain
B. it's composed of an axon.
C. it transmits nerve signals from one area of the CNS to another.
<span>D. it's composed of dendrites
The correct answers are A and D
The gray matter of the brain is made out of nerve cell bodies, dendrites, and unmyelinated axons. The outer layer of the brain's cortex is made out of the gray matter and the inner layers are made out of white matter.
The white matter is made out of </span>myelinated axons that transmit nerve signals throughout the nervous system. The white matter is white because the myelin that surrounds the axons is white.
A. hyperpnea - required so the body can meet the metabolic demand of tissues
B. From stamen to the pistil
