Describe the circumstances of a solar eclipse.

Biology
1 answer:
dangina [55]3 years ago
3 0

A solar eclipse happens when the Moon passes in front of the Sun and casts a shadow across Earth.

For a total eclipse to take place, the sun, moon and Earth must be in a direct line. The second type of solar eclipse is a partial solar eclipse. This happens when the sun, moon and Earth are not exactly lined up. The sun appears to have a dark shadow on only a small part of its surface.

What is mRNA?
Deffense [45]

Answer:

Messenger RNA is a type of RNA that is necessary for protein production. In cells, mRNA uses the information in genes to create a blueprint for making proteins. Once cells finish making a protein, they quickly break down the mRNA. mRNA from vaccines does not enter the nucleus and does not alter DNA.

So the answer will be C or A

Effector molecule binding changes the behavior of enzymes by altering the equilibrium between the tense (T) state and the relaxe
9966 [12]

Answer:

Explanation:

<h2>Homotropic effector-</h2>
  • \text{accounts for the sigmoidal nature of a velocity versus substrate concentration curve}
  • \text{An enzyme's substrate.}
<h2>Both -</h2>
  • \text{Works by altering T/R ratio.}

The phrase  \text{"accounts for the sigmoidal nature of a velocity versus }

is relevant and can be applied for homotropic effector molecules since the heterotropic effector molecules have the possibility and affinity to change the sigmoidal curve to a more potential hyperbolic curve contingent upon the allosteric effector to be positive or negative modulator.

The expression isn't relevant for both homotropic and heterotrophic effectors since the two of them can tie to the allosteric site of allosteric enzymatic compounds.

The phrase \text{"works by altering the T/R ratio"} is significant and can be applied for both homotropic and heterotropic effectors.

The expression \text{"an enzyme's substrate"} is significant and applied for homotropic effectors just as when substrate molecules tie to the allosteric site of enzyme then it is regarded as homotropic effectors. The heterotropic effectors are effectors apart from substrate molecules.

The phrase \text{"alters the} \  K_m \ \text{ of an enzyme"} is not applied and insignificant to none of the heterotropic or homotropic effector molecules since K_m is significant for the enzymes that obey the Michaelis-Menten equation, but allosteric enzymes do not obey the Michaelis-Menten equation. Homotropic and heterotropic effectors are viable and efficient for allosteric enzymatic chemicals that don't contain
