Answer:

In the real world, with its limited resources, exponential growth cannot continue indefinitely. Exponential growth may occur in environments where there are few individuals and plentiful resources, but when the number of individuals gets large enough, resources will be depleted and the growth rate will slow down.

Answer:

Explanation:

The scarcity of natural examples is due to the fact that there are population controls due to a limiting amount of resources such as food, light, shelter, water as well as to factors such as predation, climatic change, and disease.

<h2>Disruptive Selection.</h2>

Explanation:

Disruptive selection is also known as Diversifying selection.

Disruptive selection helps in determining the changes which is seen in population genetics,

The disruptive selection favours those individuals which have the smallest and largest values of the trait or characteristics.
These individuals possess the highest fitness.
The individuals which have an intermediate values have lower fitness.
The example of Disruptive selection is seen in Male lazuli buntings Feather colour which is also kown as Passerina amoena.
Passerina amoena is a bird species which is native to North America.

While ____ hormones can travel freely in the blood,_____ hormones require a carrier protein because they are not soluble in the

Mandarinka [93]

Answer:

While <u>water soluble</u> hormones can travel freely in the blood, <u>lipid soluble </u>hormones require a carrier protein because they are not soluble in the aqueous plasma

Explanation:

The water-soluble hormones such as insulin are dissolved in the blood and are carried along with the blood to their target cells.

However, lipid-soluble hormones such as steroid hormones (cortisol) and thyroxine are hydrophobic in nature. These hormones are not dissolved in water-based blood plasma. So, these lipid-soluble hormones are carried through the carrier proteins.

Organelles needed to form cilia flagella

jeka94

$Centrioles. A basal body is a centriole, which is a cylinder-shaped structure composed of microtubules that in turn contain up to 13 protofilaments surrounding a hollow center. Basal bodies are the organelles needed to form cilia and flagella.{ The protofilaments are polymers of the protein tubulin.$

genetic drift

Explanation:

Genetic drift is changes in allele frequencies of a gene pool due to chance or random events. This can occur in large or small populations. Genetic drift causes gene pools of two isolated populations to become dissimilar as some alleles are lost and other are fixed.
