Answer:

It occurs in organisms because an organism with a beneficial trait/mutation have a higher chnace of surviving compared to organisms that do not. So the organsims that do survive pass on their genes to the next generation, and the bext generation will pass on those genes to the generation after and so on. But all the organisms that do not possess a beneficial trait/mutations will not survive, therefore they cannot reproduce and pass on those genes to their offspring. This means that most of the population will posses that trait/mutation.

Example: Spotted moths camouflage with bark so they are seen by predators and eaten. Black moths are easily seen by predators and are eaten. Spotted moths then pass on their genes to the next generation of moths.

Pulse-chase experiments and protein location

ExtremeBDS [4]

Answer:

The correct answer is option - phagocytosis.

Explanation:

The explained experiment is the pulse-chase experiment in this the cells that are involved are macrophages. Macrophages are the immunity cells that have a large number of the lysosomes for killing the pathogens enters in the cell brought into the cell through the process of phagocytosis.

Phagocytosis takes place with the help of the enzyme called hydrolytic enzyme that is synthesized in the endoplasmic reticulum and modified by Golgi and moves to the lysosome.

Thus, the correct answer is option - phagocytosis.

Triangle ABC is an equilateral triangle with side lengths labeled a, b, and c. Triangle A B C is an equilateral triangle. The le

kirill115 [55]

Answer:

One-half b c sine (60 degrees)

One-half a squared sine (60 degrees)

StartFraction a b sine (60 degrees) Over 2 EndFraction

Explanation:

The area rule states that the area of any triangle is equal to half the product of the lengths of the two sides of the triangle multiplied by the sine of the angle included by the two sides.

From the question, Equilateral triangle refer to a triangle with equal angle and equal sides. The sum of an angle in a triangle = 180°; this implies that each angles have 60°.

∴ the three options that defines the expressions that represent the are of triangle ABC are:

One-half b c sine (60 degrees)

i.e $\frac{1}{2}bcsin60^{0}$

One-half a squared sine (60 degrees) ; if the two opposite sides posses the same parameters.

i.e $\frac{1}{2}a^{2}sin60^{0}$

StartFraction a b sine (60 degrees) Over 2 EndFraction

i.e $\frac{absin60^{0}}{2}$
