Is this Biology? I learned this in Chemistry!
Answer: A - non-polar Covalent Bond
The hydrogen and oxgen are attracted to each other.
The 'H+' being slightly polar, and the 'O2-' slightly opposite.
I’m pretty sure it’s skeletal muscle:) hope you have a nice day
Genetic engineering is due to the human selection of desired phenotypes, whereas natural selection is a slow process of differential survival and reproduction.
<h3>What does natural selection mean?</h3>
According to the evolution theory, natural selection is a slow process of differential survival of the fittest organisms in a given environment.
Conversely, genetic engineering refers to the molecular biology techniques used in the laboratory to produce organisms expressing desired phenotypes.
In conclusion, genetic engineering is based on human molecular biology techniques, whereas natural selection refers to differential survival and reproduction in nature.

Survival I think (sorry if im wrong)
Answer:
Rubber on steel and Rubber on dry concrete
Explanation:
Friction is the force of resistance on the solid motion surfaces.
Coefficient of The ratio of frictional force between two body and the forces that brings them together. It depends on the temperature, velocity of the object involved.
Rubber is said to exhibit a high coefficient of friction with other surface ranging from 1 to 2 while Dry surface material yield between 0.3 to 0.6. When friction is greater than 1 it means the force that is needed to slide or move an object on the surface is greater than the force that exist on the surface of the object.
