Answer:
<u>G. Nitrogenous base</u>
Explanation:
Double-stranded DNA (Deoxyribonuclease) molecules store genetic information. Their 5-carbon deoxyribose sugar, phosphate and one of four nitrogenous bases from which nucleotides derive their name:
The nucleotides on a single strand are bonded together via covalent bonding. Base pairs are formed between nucleotides on opposite strands, due to hydrogen bonding between bases. For instance, <u>Adenine forms double bonds with thymine, while cytosine forms triple bonds with guanine.</u>
A dichotomous key is a tool that helps the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish.
I agree with the other one “The sperm whale has a diploid complement of 2n=42 and the killer whale a complement of 2n=44. These two species, though different in chromosome number, have karyotypes which have no t group chromosomes and more m group chromosomes than the typical whale karyotype.”
Answer:
Diffusion is the passage of molecules from a high-concentration region of the molecule to a lower-concentration area of the molecule.
Facilitated diffusion is the passage of a molecule with the assistance of a protein channel or carrier from a region of high concentration to an area of lower concentration.
Hope this helps!
