A neurotransmitter may have an excitatory or an inhibitory effect on the postsynaptic cell, depending on __________.
Otrada [13]

A neurotransmitter can have an excitatory or inhibitory effect on the postsynaptic cell, depending on <u>which of its </u><u>receptor(s</u><u>) are present on the </u><u>postsynaptic</u><u> (target) cell.</u>

<h3>How do excitatory and inhibitory neurotransmitters act?</h3>

Sometimes neurotransmitters can bind to receptors and cause an electrical signal to be transmitted through the cell (excitatory). In other cases, the neurotransmitter can prevent the signal from continuing, preventing the message from being carried (inhibitory).

With this information, we can conclude that a neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.

3. What would happen if they crossed yellow jellyfish with coober Complete
lidiya [134]

Answer:

We know that the color of jellyfish is controlled by codominance inheritance pattern and yellow Y and blue B are two alleles and in case of heterozygous the goober or green color occurs then,

If Yellow jellyfish is crossed with goober, that is, YY X YB.

 the punnett square will be -

   Y      Y

Y   YY    YY

B  YB     YB

The possible genotype of offspring will be YY, and YB and therefore, the possible phenotype of offspring will be Yellow, and Green. The Percentage of yellow offspring will be 50% as two out of four are dominant for Y allele and two heterozygous conditions that is 50 % and as there are two copies B alleles are not present so zero percent of blue color.

In a field of sunflower plants, 776 plants are tall and 224 plants are short. Sunflower height follows the normal pattern of inh
Nitella [24]

Answer:

The correct answer would be D) tt.

Recessive traits need a homozygous condition to get expressed and to produce a particular phenotype. In contrast, dominant trait can be expressed  in homozygous as well as heterozygous condition of the alleles of a gene.

Now, shortness is a recessive trait encoded by allele "t". Hence, allele "t" must be present in the homozygous condition in order to make the plant short.

Thus, the genotype of all the short plants in the field should be tt and the genotype of the tall plants would be TT or Tt.
