There are a couple reasons the ice is important to polar bears, but given the choices you have the correct one would be:

A. The polar bears can’t out swim the seals, so they sit quietly on an ice platform and attack the seals when they come up for air.

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>

$\text{accounts for the sigmoidal nature of a velocity versus substrate concentration curve}$
$\text{An enzyme's substrate.}$

$\text{Works by altering T/R ratio.}$

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

Diagnose: Mrs. Harris is a 60 year old white woman. She has noticed in recent years that her height has slightly decreased. Rece

Brut [27]

Answer:

Q: Which skeletal system disorder might she be suffering from?

A: Osteoporosis

Q: What techniques could be used to diagnose her condition?

A: Bone mineral density (BMD) test or dual energy X-ray absorptiometry (DXA) scan

Q: What treatments are available?

A: Medication, healthy food.

Explanation:

The vertebral discs between vertebrae could shrink with age. Therefore, a height loss up to 1-inch is normal. However, if the height loss is more then it is possibly due to osteoporosis.

A bone mineral density test, also known as dual energy X-ray absorptiometry scan, is a well-adapted test to measure the amount of calcium and other minerals in the bones. It uses X-rays to measure the content of calcium and thus strength of bones.

A person who is already suffering from osteoporosis should be treated with medicine right away so that it stops further deterioration of the bones and avoid any future bone fractures. Further, it can be handled by eating a healthy diet and supplements such as vitamins D. In case some of the bones/vertebrae are already fractured, surgical approaches might be necessary.
