Answer:

e) are continuously modified so that they are always matched to the environment in which a population lives

Explanation:

The role of natural selection is to select individuals best adapted to a given ecological condition, allowing them to survive and leave descendants in a given environment.

Natural selection acts permanently on all populations. Even in stable and constant environments, natural selection acts in a stabilizing manner, is present, eliminating divergent phenotypes.

However, the environment does not represent a constant and stable system, in fact, it is always changing, both over time and throughout space, which determines different interactions between organisms and the environment.

If you double the force on the object what is the result on the acceleration?

Zepler [3.9K]

Answer:

As we increase the force on an object the acceleration increases proportionally. ... Therefore, if you double the force you double the acceleration. If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration.

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 $\frac{absin60^{0}}{2}$
