Answer:

The three main rock types are igneous, metamorphic, and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

Which lipoprotein carries cholesterol to the cells in your body, but can get stuck in arteries while traveling in the blood, dep
Viktor [21]

LDL (low-density lipoprotein) carry cholesterol from the liver to the tissues and can contribute to the formation of plaque that builds up in the arteries.

<h3>What are lipids?</h3>

Lipids are soluble in fat and to circulate in the blood, which is an aqueous medium, they form lipoprotein complexes called lipoproteins, these constitute a transport medium and circulating reservoir for lipids.

<h3>Characteristics of LDL (low-density lipoprotein)</h3>

  • Low-density lipoproteins, composed of 50% triglycerides, are the ones that transport the lipids synthesized in the liver to other parts of the body.

  • LDL, composed mainly of cholesterol, when in excess, also deposits it on the walls of the arteries, contributing to the formation of plaque.

Therefore, we can conclude that excess LDL (low-density lipoprotein) poses a health risk because it facilitates the accumulation of fat in the arteries.

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

Leni [432]

Answer:

Amount of DNA in a diploid G2 nucleus after S phase has already undergone DNA replication hence the amount of DNA in a diploid nucleus in G1 would be 200 ng. As the organism is diploid, 200 ng of DNA would be carried on 14 chromosomes.
