The correct answer is B
The genetic codes language in all living organisms is the same. This is to say that the molecules of life namely DNA and RNA share the same make up in all living things .
There are five types of nucleotides in nature which are the building blocks of RNA and DNA and these are the same in all living organisms . These nucleotides are Adenine, Thymine, Guanine, Cytosine and Uracil.
According to base pairing rules, in all DNA molecules Adenine will always pair with Thymine while Guanine will always pair with Cytosine.
This rule is the same with RNA except that here Thymine is replaced with Uracil. Otherwise the base pairing rule applies in all living organisms, that is to say it is universal.
Answer:
The correct answer is-a polysaccharide found in animals
Explanation:
Glycogen is a polysaccharide which is a highly branded form of amylopectin. In glycogen glucose residues are joined together by α1-4 glycosidic linkage and α 1-6 branching points occurs after every 8-10 glucose residues.
Glycogen is the main carbohydrate storage form of carbohydrates in animals. Glycogen is mostly present in liver and muscles. It breaks down into glucose and provide energy to the animal during the physical activity. Therefore glycogen is polysaccharide found in animals.
B. A food chain has limitations with the organisms involved
