The correct option is C. Increase Na⁺  permeability

An excitatory postsynaptic potential(EPSP) is generated when positively charged ions flow into the postsynaptic cell due to the opening of ligand-sensitive channels. Due to more influx of sodium ions the positive charge inside the neural cell increases and so, it becomes depolarized.

The function of the sodium-potassium pump is to maintain the osmotic equilibrium and membrane potential in the cells. As the ions sodium and potassium move against the concentration gradient, this pump helps to maintain their flow.

K⁺ ions are present in greater amounts inside the cell and  Na⁺ ions are present in greater amounts on the outside. If the permeability for K⁺  increases the membrane inside will become even more negative and it will lead to hyperpolarisation of the neuron.

A)Exons 2 and 3 must have the same number of nucleotides. B)Exons 2 and 3 must contain an integral number of codons (that is, th
Thepotemich [5.8K]

Answer:

Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.

Antipsychotic drugs (intended to relieve schizophrenia) act by doing what?
Debora [2.8K]
<span>Anti­psychotic drugs generally work by blocking a specific subtype of the dopamine receptor, known as the D2 receptor. This helps to regulate the functioning of brain circuits that control thinking, mood, and perception.</span>

Questions:
Neporo4naja [7]

Explanation:

1. cell membranes are partialy permeable, only allowing passage to some certain molecules.

2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.

3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.

If cyanobacteria never evolved during earth's history, how would their absence affect the composition of earth's atmosphere?
Blababa [14]
Cyanobacteria, also known as blue-green algae, are found in vast quantities in fresh and salt water. Cyanobacteria are able to conduct photosynthesis. By utilising energy from the sun, they produce carbohydrates from water and carbon dioxide. As a byproduct, they produce oxygen. So cyanobacteria provided oxygen to the atmosphere that allowed other lifeforms to develop.
