Vedmedyk [2.9K]2 years ago
7 0

Explanation:

In biology, homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems.This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium and calcium ions, as well as that of the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life.

Several species of leopard frogs are common throughout North America, where their ranges overlap. Different species of leopard f
MrMuchimi

the correct answer is A- Reproductive isolation occurred through behavioral isolation

A process of formation of a new species from an existing species is called speciation. New species may formed due to geographical or reproductive barriers which isolates the members of a population of a species to form a new species.

In the given question, speciation in In the leopard frogs occurred due to a particular or specific call given by males to the females. The courtship call lead to reproductive isolation due to change in behavior. Such type of behavioral change will help in recognizing mates of the same species and this will act as a reproductive barrier among the other related species.

Explain how a mutation near, but outside of, the coding region of Pitx1 may cause a loss of pelvic fins without pleiotropic effe
ipn [44]

Since the Pitx1 gene codes for a protein crucial im lower limns development, a mutation occurring near Pitx1 gene will affect refikjs around the lower limbs but not those far away from it.

<h3>What are mutations?</h3>

Mutations refers to alterations or error that occur which change the original sequence of nucleotides in a DNA molecule.

The Pitx1 gene is a gene that codes for a protein that involved in development of the lower limbs.

A mutation near but outside of the coding region of Pitx1 may cause a loss of pelvic fins without pleiotropic effects on the pituitary gland and jaw because the pelvic fins form part of the lower limbs whole the jaws and the pituitary gland are not found in the lower limbs.

Therefore, the mutation occurring near Pitx1 gene will affect regions around the lower limbs but not those far away from it.

Which statement most accurately explains how allosteric regulation can change an enzyme's catalytic activity? View Available Hin
Digiron [165]

Answer:

In allosteric inhibition, a regulatory molecule binds to a location other than the active site, resulting in a change in enzyme shape that allows the active site to bind substrate.

Explanation:

Allosteric regulation of an enzyme can be positive or negative, but it always involves effector molecules that bind to non-active site of the enzyme and change its conformation. That site of binding is called allosteric or regulatory site. If the enzyme activity is enhanced effector molecule is called allosteric activator but if the activity is decreased effector molecules are allosteric inhibitors.
