Answer:
the four zones found in the ocean:
<em>the intertidal zone,</em> which is the area of the seashore that's underwater at high tide and above water level at low tide. this zone also has various kinds of organisms, like seastars, sea urchins and a lot of different species of coral !
<em>the pelagic zone,</em> which could be described as all of the sea other than the sea along the shoreline or the bottom of the ocean. it's funny because the word is actually derived from ancient greek, and the word pelagic literally means
"<em>open sea</em>" !
<em>the abyssal zone,</em> which can also be called the abyssopelagic zone (i don't even know how to say that-) describes the "depths" or the very bottom of the ocean, especially between about 10,000 and 20,000 feet (3,000 and 6,000 m) down !
and <em>the benthic zone, </em>which is made up of the "bottom", like the bottom of a lake or ocean floor, the sediment surface, and some sub surface layers. there's actually organisms living in that zone, too, and they're called benthos ! (i think that's really cute, lil benthos uwu)

If a post-synaptic ionotropic receptor is permeable to potassium and assuming all normal ionic distributions, the response in the post synaptic cell will be inhibitory.
- Ion channels that open in response to the binding of a neurotransmitter are known as ionotropic receptors, also known as neurotransmitter-gated or ligand-gated channels.
- If there is a synapse, they can be found anywhere along the neuron, though they are typically found around the dendrites or cell body.
- Ligand-gated channels play a crucial role in the transmission of information from one neuron to another.
- Postsynaptic receptors can identify two different kinds of neurotransmitters.
- The action potential is swiftly transmitted by ionotropic receptors, also known as ligand-gated ion channels, to depolarize the neuron (or hyperpolarize the neuron and inhibit additional action potentials).

Answer:
C) Population bottleneck reduced genetic diversity, as the gene pool of the 30,000 elephant seals resulted from the few alleles present in the 20 bottleneck survivors.
Explanation:
<u>The correct answer would be that population bottleneck reduced genetic diversity, as the gene pool of the 30,000 elephant seals resulted from the few alleles present in the 20 bottleneck survivors.</u>
A sudden decrease in the population of an organism as a result of disaster or any other factor leads to a population bottleneck - a decrease in the genetic variability of the population.
<em>The decrease in the available number of alleles in the population limits the amount of genes that natural selection can influence. Hence, as the population keeps increasing, the genetic diversity of the entire population rarely changes because the few alleles present in the population keep recombining.</em>
The correct option is C.
Answer:
sickle cell anemia is not expressed
Explanation:
Biologists who work in the fields of genomics and molecular biology study DNA genome content and analyze genetics on a molecular level. They do it to map DNA and use it to prevent diseases or anything similar.
