Agalaxy is likely to be a collection of which of the following 1. universe and interstellar matter 2. stars and interstellar matter 3. clusters and constellations*** 4 stars and clusters

Stars and interstellar matter

Explanation:

Clusters are a group of galaxies so that can't be correct. A universe is bigger than a galaxy so it can't be that. Constellations are a group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure. So the only answer is stars and interstellar matter.

answer; i believe the answer is (polygenic inheritance;

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."
