Describe two ways polar bears are well adapted to surviving during the Arctic winter.

cricket20 [7]

They are well at surviving because of their thick white coat. The white fur helps them blend in with the snow and ice. The polar bear also has a layer of fat under their skin so they can survive harsh temperatures.

With the knowledge of the nucleotide sequence of a gene, which one of the following could you determine with the most accuracy?

Lubov Fominskaja [6]

<u>Primary structure of the protein </u>can be determined With the knowledge of the nucleotide sequence of a gene.

Strings of amino acids make up proteins, and strings of nucleotides make up nucleic acids.
A water molecule is removed during a biological process that links the carboxyl group of one amino acid to the amino group of a nearby amino acid to generate peptide bonds.
The main structure of a protein is thought to be its linear amino acid sequence.
A codon is a cluster of three mRNA nucleotides that codes for a particular amino acid.
Each mRNA produces a protein that has a specific amino acid sequence corresponding to it. The start and stop of translation are indicated by two codons known as start and stop codons.
