question2
why urctic forx change coloring from brown in summer and white in winter .
My answeers is = fox change phenotype but genotypes does not chane?
am i right ?

If there is a tutor here who can help you with this particular question, I'm sure he/she will add a response.
Phosphodlester bond
For your first question, the covalent bond between the monomers of an enzyme macromolecule is a peptide bond. Enzymes are proteins, and proteins are made up of amino acid monomers linked together by peptide bonds to form a polypeptide chain.
Regarding your second question, the change in coloring of arctic foxes from brown in summer to white in winter is due to both changes in their phenotype and genotype. The phenotype refers to the observable characteristics or traits of an organism, while the genotype refers to the genetic makeup of an organism.
Arctic foxes have seasonal adaptations, including changes in fur color, to blend in with their environment. The change in fur color is mainly a result of genetic changes or variations in their genotype, which are triggered by environmental cues such as changes in day length. In summer, when the Arctic landscape is predominantly brown and tundra vegetation is present, the fox's fur turns brown to provide camouflage. In winter, when snow covers the environment, the fox's fur turns white to help it blend in with the snowy surroundings.
So, in this case, both the phenotype (fur color) and the genotype (underlying genetic changes) of the arctic fox change to adapt to the seasonal variations in their environment.
