Answer:
The correct answer would be alpha amylase.
Alpha enzyme is an enzyme that catalyzes the break down of alpha linkage present in polysaccharides such as starch, glycogen et cetera.
The help in breaking down complex polysaccharides into simpler units which can be easily absorbed by the body.
For example, alpha amylase is present in the form of salivary amylase and pancreatic amylase in humans. They breakdown the starch into smaller units such as maltose and dextrin.
In contrast, oligo-1,6-glucosidase is an enzyme that catalyzes the breakdown of alpha 1-6 linkage in some oligsaccharides.
Thus, the organism would miss alpha amylase more as compared to oligo-1,6-glucosidase.
Spines primarily have a protective function in plants. The spines can be sharp, and form a physical barrier against herbivores which may want to feed on the plant. Spines however also have other benefits. The spines on a jumping cactus allow segments of the cactus to stick to passing large animals or humans, thereby allowing the cactus to spread to other areas through asexual propagation. Spines are modified leaves, and spines have a much lower surface area than leaves, and therefore can reduce transpirative loss of water by the plant during harsh droughts. Some trees in alpine regions, such as pine trees, have developed spine-like leaves to prevent the accumulation of snow in the branches.
C: chimpanzee we share more traits with monkeys, therefore the answer is chimpanzee.
