Answer:
Variation in gene leads to anatomical difference in the closely related species
Explanation:
Though some organisms are morphologically very different from each other, yet they can belong to same species group. It is because of shared genetic framework with minute changes.
For example – Human and chimpanzees have similar genes and share about 99 percent their genes with each other.
The variation in 1 % gene has led to visible anatomical differences such as varying lengths of arms, jaw structure and size etc.
The same is the case with six living species of mammals and their close relationship with dugongs and elephants
Answer:
b. secondary active transport by a symporter
Explanation:
Glucose is a monosaccharide, one of the digestion products of carbohydrates. Glucose is a polar molecule and can not diffuse through the hydrophobic core of the cell membrane of absorptive cells of the small intestine.
A symporter transports one glucose and two sodium ions from the cavity of the small intestine into the absorptive cells of the villi. Since both Na+ and glucose are transported in the same direction, it is a symport. Here, the energy of the ionic concentration gradient of Na+ serves as a source of energy for glucose transport, the process of glucose transport is secondary active transport.
