Dna sequences can act as ""tape measures of evolution"" (see concept 3.7). some highly conserved regions of the human genome (similar to comparable regions in other species) don’t code for proteins. propose a possible explanation.

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

what are the options

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
