Q:

Rolling friction is caused by ____ from the following?

A) Non-elastic effects B) Gravity
C) Power dissipation D) Buoyancy
 
Answer & Explanation Answer: A) Non-elastic effects

Explanation:

Rolling friction or rolling drag is the force resisting the motion when a body rolls on a surface. It is mainly caused by non-elastic effects, that is, not all the energy needed for deformation of the wheel, roadbed, etc... is recovered when the pressure is removed.

Another cause of rolling resistance lies in the slippage between the wheel and the surface, which dissipates energy.

Q:

Heritable variation is required for which of the following?

A) Evolution B) Asexual reproduction
C) Mitosis D) Meiosis
 
Answer & Explanation Answer: A) Evolution

Explanation:

Heritable variation is one of the four most important factors that affect whether natural selection can occur. These factors include

1) Heritable variation

2) Descent with modification

3) Struggle for survival, and necessarily if the others are satisfied

4) Survival of the fittest.

Heritable variation allows for possibly beneficial, negative, or even neutral mutations to get filtered during each generation by natural selection--weeding out negative mutations, passing on positive and neutral ones. Without heritable variation, species would quickly fall victim to parasites who take advantage of identical genetic material in a population and evolution would not occur.

Variation is the raw material of evolution.
