Correct option is A)

There are electrical and concentration gradients in neurons that induce the sodium ions to enter the cell. The resting potential is maintained because the channels for sodium ions are closed. The membrane remains impermeable to sodium ions in the rest state. The membrane is more permeable to potassium passage. The potassium ions leak through the membrane at a greater rate than sodium enters. There is loss of positively charged ions from the inner part of the cell membrane. The inner part of the membrane carries a relatively more negative charge than the outer part of the cell membrane.

Thus, the correct answer is option A.

C.
Its C because basically when the neuron is being stimulated its excited like in gas where the the atoms are super hyper. On the other hand in things like ice the atoms are not moving at all but they have the potential to moving making the right choice C

Answer:

Explanation:a) low melting point

Poor conductivity

: Low solubility

Low solubility The mass is equal to the sum of the masses of all the individual atoms in the molecular structure.

b) The cross-sectional area of the fluid.

Therefore The diffusion coefficient is a physical constant dependent on molecule size and other properties of the diffusing substance as well as on temperature and pressure.

ATP is not generated directly in the citric acid cycle. Instead, an intermediate is first generated by substrate-level phosphorylation. The intermediate is GTP.

A purine nucleoside triphosphate is guanosine-5'-triphosphate.
It serves as one of the components necessary for the creation of RNA during transcription.
The main distinction between its structure and that of the guanosine nucleoside is the presence of phosphates on the ribose sugar of nucleotides like GTP.
Also known as guanosine triphosphate, this energy-dense nucleotide is similar to ATP and is made up of guanine, ribose, and three phosphate groups.
It is required for the creation of peptide bonds during protein synthesis.
Adenine nitrogenous base, sugar ribose, and triphosphate make up ATP, a nucleoside triphosphate, whereas guanine nitrogenous base, sugar ribose, and triphosphate make up GTP.
This is the main distinction between the two compounds.
The alpha-guanosine subunit's diphosphate (GDP) is converted into guanosine triphosphate (GTP), and the GTP-bound alpha-subunit subsequently separates from the beta- and gamma-subunits.

Answer:

Explanation:

The DNA is made 4 nitrogenous bases. A (adenine) pairs with T (thymine) and are held by two hydrogen bonds. C (cytosine) pairs with G (guanine) and are held by three hydrogen bonds.

You might wanna remember this by the preposition 'at', which ultimately makes C and G together. Or you might wanna remember it by something like G- C<em>AT</em>.
