Answer:Glucose is changed into pyruvate.
Explanation: Glycolysis is a 10step enzyme catalysed reaction. Glucose us broken down to pyruvic acid
The right answer is a person has more than two alleles for a certain trait.
Duplication is a genetic mutation characterized by the doubling of genetic material on a chromosome. There are several mechanisms that result in the duplication of either a large chromosomal portion, a gene, or a nucleotide sequence.
Answer: c. Amino Acids
Explanation:
Food is chemically and mechanically broken down into smaller particles like building blocks, the smallest of these are a basic unit called monomers. In the <em>stomach</em>, the enzyme pepsin breaks proteins, like those found in salmon, into smaller peptides by splitting the peptide bonds holding the proteins together. The <em>duodenum</em> processes these newly-formed peptide chains or polypeptides, into smaller ones, through the enzyme action of elastase, trypsin and chymotrypsin; these are produced in the pancreas. Peptidases convert these fragments into amino acid monomers for absorption into the bloodstream via the small intestines.
The correct options are as follows"
1.B.
Postzygotic isolation is a type of reproductive isolation which keeps species from mating with each other as a result of the differences that developed between them when they are separated by physical boundary. In the question given above, the lizard specie has been separated by the formation of a stream which divide the region into two.
2.B.
Allopatric speciation refers to the mode of speciation that occur when biological population of the same specie become isolated from each other to an extent that it interferes with genetic interchange. It usually occur as a result of change in the environment.
