Which element matters least in the process of natural selection?
Lapatulllka [165]

Given question is incomplete as it lacks the group of choices. However, the group of choices associated with the question is as follows:

1. Organisms must display variation.

2. A trait must increase reproduction.

3. A trait must directly affect metabolism.

4. A trait must increase survival.

5. A trait must be able to be passed on to future generations.

Answer:

The correct answer is : option 3. A trait must directly affect metabolism.

Explanation:

The process that leads to change or adaption in the species or a population of the organism known as natural selection. In this process population exhibits the variation in the population due to the change or adaption.

This variation refers to the better traits and increased reproductive ability, suited to the environment than others which is also known as survival of the fittest as they increase their survival in comparison to the other population or species. Natural selection carries traits that are passed on to one generation to another.

Thus, the correct answer is option Is : 3. A trait must directly affect metabolism.

The ball with a mass of 1.5 kilograms is tied to the end of
Hunter-Best [27]

Solve the

potential energy at point B


PE = mgh


Where m is

the mass


G is the

acceleration due to gravity 9.8 m/s2


H is the height


PE = ( 1.5

kg) ( 9.8 m/s2) (0.5 m)


PE = 7.35 J



Solve the

velocity using the


KE = 0.5mv^2


Where ke is

the kinetic energy


M is the

mass


V is the

velocity


Since all

energy is converted to KE


So KE = PE



7.35 = 0.53(1.5)

v^2


V = 3.13 m/s
