A genetic mutation causes a squirrel to be born with much darker fur than its parents. How will this mutation most likely affect the squirrel population? Because the trait was caused by a mutation, it will not be passed on to any offspring, resulting in the disappearance of the trait. Because the trait was caused by a mutation, it will be passed on to offspring over many generations, resulting in a population of darker squirrels. If the trait is unfavorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels. If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.

"a scientist studying a whale and its surroundings would need to understand the structure of atoms in case something was negatively affecting the whale or its surroundings."

explanation:

this was from the link provided:

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!
