What is polygenetics ?

Explanation:

is a member of a group of non epics tactic genes that interact additively to influence a phenotypic trait

Answer (three definitions, where two are biology and one is geology):

1) (biology) Of or pertaining to polygenesis; polyphyletic.

2) relating to or determined by polygenes.

If you don’t know what a polygene is: A polygene or multiple gene inheritance is a member of a group of non-epistatic genes that interact additively to influence a phenotypic trait.

3) (geology) One which is composite, or consists of two or more monogenetic ranges, each having had its own history of development.

Hope this helps! :)

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
