Answer:
The correct answer is d. suggests that the time since divergence may not be sufficient for complete reproductive isolation to have occurred.
Explanation:
Polar bears are evolved from brown bear and grizzly bears are subspecies of brown bear so polar bears and brown bears are different species. These two species habitat is different so they are geographically isolated but due to the melting of ice by global warming, their niche started overlapping.
Commonly they do no reproduce with each other because of the reproductive isolation but they can produce viable hybrids called growlers and pizzlies if interspecies reproduction takes place which shows that the time interval since divergence is not enough that can make these two species completely reproductive isolated. So the right answer is d.
Answer: Glycosidic bonds.
Explanation:d
Glycosidic bonds are covalent bonds that join monosaccharides or longer glucose chains to other monosaccharide or carbohydrates to form disaccharides, oligosaccharides and polysaccharides and are named according to the type of the atom present on the second carbohydrate to be linked. The bond is usually formed between the hemiacetal of the first carbohydrate and the functional group on the second molecule which could be Oxygen-, Nitrogen-Sulphur -, and Carbon -glycosidic bonds.
Examples of Polysaccharides are Cellulose Starch , Glycogen formed by the linkage of many long residue monosaccharides connected through glycosidic bonds.
