Neurotransmitters can affect postsynaptic cells by I) initiating signal transduction pathways in the cells II) causing molecular
Yakvenalex [24]

Neurotransmitters can affect postsynaptic cells by causing molecular changes in the cells.

The term "chemical messengers of the body" is frequently used to describe neurotransmitters. The nervous system uses these molecules to send information between neurons or from neurons to muscles. A neurotransmitter influences a neuron in one of three ways: excitatory, inhibitory or modulatory.

When a stimulus is potent enough, the chemical messenger neurotransmitter is transferred into the nerve impulse. If it is powerful enough, it will reach the postsynaptic cell and affect the structure of the neuron. And when signal transduction happens, everything mentioned above is completed.

Arrange the following estuarine zones in decreasing order of salinity.
Maksim231197 [3]

Answer:

Euhaline  ⇒  Polyhaline  ⇒  Mesohaline  ⇒  Oligohaline

Explanation:

Let's first define each of these levels:

- Polyhaline: a category of salinity that has medium-high levels of salt

- Mesohaline: a category of salinity that has medium levels of salt

- Oligohaline: a category of salinity that has low levels of salt

- Euthaline: a category of salinity that has high levels of salt

Now, we can order these in decreasing order of salinity:

Euhaline  ⇒  Polyhaline  ⇒  Mesohaline  ⇒  Oligohaline

An individual having two different alleles of a specific gene is described as being _________ for that specific trait.
borishaifa [10]

An individual having two different alleles of a specific gene is described as being Heterozygous for that specific trait.

You have a heterozygous genotype for that gene if the two versions differ. Being heterozygous for hair color, for example, means you have one allele for red hair and one allele for brown hair. The interaction of the two alleles influences which traits are expressed.

Being homozygous for a gene means you inherited two identical copies. It is the inverse of a heterozygous genotype, in which the alleles differ. People with recessive characteristics, such as blue eyes or red hair, are always homozygous for that gene. In genetics, heterozygous means having inherited different versions (alleles) of a genomic marker from each biological parent. As a result, a person who is heterozygous for a genomic marker has two distinct versions of that marker.
