<h3><u>Answer;</u></h3>

b). Activation of an upstream guanine nucleotide exchange factor

<h3><u>Explanation</u>;</h3>
  • <em><u>When a ligand activates the G protein-coupled receptor, it induces a conformational change in the receptor that allows the receptor to function as a guanine nucleotide exchange factor (GEF) that exchanges GDP for GTPthus turning the G protein-coupled receptor on.</u></em>
  • The activated G-protein then dissociates into an alpha (G-alpha) and a beta-gamma complex.

If velocity is positive, which would most likely yield a negative acceleration?
Lesechka [4]
<span><span>B. A time that is less than a half hour.

</span>Acceleration = Velocity / Time
Greater velocity / Lesser time
Greater Velocity = greater acceleration

Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)</span>

what is difference between the name of an object versus the chemical formula?please answer my question I'm trying that from thre
Step2247 [10]

Answer:

Assuming you mean in a compound of elements: A name is just what you call it, and the chemical formula is what elements it is made of.

Explanation:

Take sodium chloride (Salt) for example. It's name is sodium chloride, but its chemical formula is NaCl. Na= Sodium, and Cl = Chlorine. So one sodium ion and one Chlorine ion create NaCl. Na+Cl=NaCl. And the name for the product of the formula is Sodium Chloride.

Another example is H2O (Water). H=Hydrogen and O=Oxygen. There are 2 hydrogens and one oxygen in H2O. H+H+O=H2O. The name for the formula is water.

What is true about chromatin
qwelly [4]
At the smallest level of organization, the DNA wraps itself around small globular proteins called histones. Complexes of histones and DNA form nucleosomes, which appear as "beads" on the DNA strand. Chromatin refers to the decondensed DNA that has not formed separate chromosomes.
