A transcriptional repressor that controls the transcription of gene A is not normally active unless bound by an effector molecul
hoa [83]

Answer:

C

Explanation:

I think its C . A transcriptional repressor usually represses the transcription pathway when its active. According to the question, the repressor is not usually active until an effector molecule binds to it making it active and blocking the transcription pathway. So if the region where the effector binds on the repressor is mutated i.e. it turns nonfunctional that means the effector cannot bind to repressor which means repressor cannot become active to block transcription which in turn increases the transcription of gene A because repressor cannot repress it since it is inactive due to its inability to bind to the effector.

Answer:

Meiosis

Explanation:

Meiosis is one of the two types of divisions that cells usually undergo. However, meiosis is unique to sexually-reproducing organisms. Meiosis is the cell division which results in daughter cells with a reduced number of chromosomes (by half). Meiosis is used to produce gametes in sexually reproducing organisms.

According to the question, Labrador retriever contains 78 chromosomes in each of its muscle cells, which is a somatic cell. Since Labrador retrievers are sexually reproducing organisms, a male one will produce gametes (sperm cells) via the process of meiosis. At the end of the meiotic process, sperm cells with 39 chromosomes each will be produced.

How does a nerve
Mashutka [201]

A positive charge is created in the cell that travels down it does a nerve

impulse begin in a neuron. Thus, the correct option is A.

<h3>How the neuron get stimulus?</h3>

When a neuron receives a chemical stimulation, a nerve impulse is formed. The electrical action potential of the nerve impulse passes along the axon membrane to the axon terminal. Neurotransmitters are released at the axon terminal, which transfer the nerve impulse to the next cell.

The resting potential of a neuron is the electrical differential across its membrane. The sodium-potassium pump, a transport protein, creates the resting potential. This protein generates a positive charge by moving a high number of sodium ions (Na+) outside the cell.
