Answer:

B

Explanation:

There is a correlation between malaria infested regions and the allele frequency of sickle cell anemia, because the non sickle cell allele frequency is decreasing faster than the sickle cell allele frequency. The S allele is being selected for during natural selection in these areas. The S allele frequency is changing far less than the A allele frequency. This shows that the A allele is being selected against, therefore, there are far fewer of those alleles being inherited in each generation compared to the S allele. This selection of the S allele coincides with the correlation that exists in malaria infested areas and sickle cell anemia.

After diffusion of a neurotransmitter across a synaptic cleft, how is the neurotransmitter typically perceived by the post-synap
Rama09 [41]

Answer:

by binding to an ion channel

Explanation:

The neurotransmitters are chemical messengers capable of transmitting a signal from a given nerve cell across biological junctions named 'synapses' to target cells such as, for example, other nerve cells (e.g., neurons). In the cell, the neurotransmitters are transported into internal vesicles that are fused with the cell membrane to release them in the synaptic cleft by the process of exocytosis. Subsequently, the neurotransmitters bind to cell receptors localized on the postsynaptic membrane and thus trigger responses in postsynaptic cells. For example, glutamate is a neurotransmitter capable of exciting nerve cells by binding to a transmitter-gated ion channel called N-methyl-D-aspartate (NMDA).
