If two people having sex in certain position then pregnancy is not possible because of gravity

It is possible either way because if you're not wearing protection, it can still happen because you're doing it raw.

Explanation:

a. a primary source combines several different accounts of an event. b. a primary source generally benefits from having been written after an event.

explanation:

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
