<span> Geographical</span> isolation refers to a population of organisms (such as plants and animals) that are separated from other species, thus unable to exchange genetic material with other organisms because of physical boundaries that isolate them or any unfavorable circumstances that prevent interbreeding.

If a ligand were stuck in the g-protein-linked receptor, what would be the effect to the cell?.
aleksandr82 [10.1K]

The pathway would be over active, If a ligand were stuck in the G-protein-linked receptor.

<h3>What usually happens when a ligand binds to a receptor protein?</h3>

When the ligand attached to the internal receptor, a change occurs that shows at DNA-binding site on the protein.

The ligand-receptor complex moves into the nucleus where it binds itself to regions of the chromosomal DNA. It promotes the initiation of the process of transcription so we can conclude that if a ligand were stuck in the G-protein-linked receptor, the pathway would be over active.

If you wanted to combine equal numbers of Na and Cl atoms in a flask, how much Cl would you have to add if you added 23g of NA?
Gwar [14]

<u>Answer:</u> The mass of chlorine atom required to combine is 35.5 grams.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}      .....(1)

  • <u>For sodium:</u>

Given mass of sodium = 23 g

Molar mass of sodium = 23 g/mol

Putting values in equation 1, we get:

\text{Moles of sodium}=\frac{23g}{23g/mol}=1mol

According to mole concept:

1 mole of an atom contains 6.022\times 10^{23} number of particles

So, 1 mole of sodium will contain = (1\times 6.022\times 10^{23})=6.022\times 10^{23} number of atoms

Number of atoms of chlorine = Number of atoms of sodium = 6.022\times 10^{23} = 1 mole

Now, calculating the mass of chlorine required by using equation 1:

Moles of chlorine = 1 mole

Molar mass of chlorine = 35.5 g/mol

Putting values in equation 1, we get:

1mol=\frac{\text{Mass of chlorine}}{35.5g/mol}\\\\\text{Mass of chlorine}=(1mol\times 35.5g/mol)=35.5g

Hence, the mass of chlorine atom required to combine is 35.5 grams.
