D cell membrane bc it moves things in and out of cell
Answer:
The suitable statement will be - only one allele appears for that gene in that population.
Explanation:
- Gene Fixation is a topic of population genetics. It means that fixing the change in a gene from a gene pool and that leads to express only one allele for that gene which only remains after the fixation process, in that population. Normally a gene exists of at least two variants or alleles.
- An allele fixation means that only one variant or allele will be expressed in all the populations.
A. Neurotransmitters diffuse across the membrane of neurons
Explanation:
When we begin to move, the brain initially sends a signal to the spinal cord, then the nerve cells in the spinal cord monitor the exact coordination of the muscles. Signal from the brain and the spinal cord directs the movement of leg muscles. Signal is transmitted by release of neurotransmitter from the neuron to the synaptic cleft and its binding to the receptor of adjacent neuron.
Alcohol works as a central nervous system depressant by <span>binding to neuron receptors.
