Answer:C
Explanation:if the few surviving amphibians reproduce and their young ones too survives, then it is genetic drift
Answer:
B. centrioles
Explanation:
Plant cells have cell walls, cell membranes and also contain mitochondria along the chloroplasts.
Answer:
a. Amyloid fibrils have a high amount of β-sheet structure.
c. Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease.
e. Proteins that form amyloid fibrils are normally soluble.
Explanation:
Amyloids can be defined as fibrillar protein aggregates composed of a β-sheet secondary structure. In general, the amyloid fibrils are composed by soluble proteins that are assembled to form insoluble resistant to degradation fibers. In humans, defective amyloid proteins produced by misfolding are known to produce diseases (amyloidosis) capable of altering the function of tissues and organs. Systemic forms of amyloidosis are common in neurodegenerative disorders.

Aerobic cellular respiration, glucose is metabolised in the presence of oxygen and leads to the formation of energy as a main product. the by products are carbon dioxide and water. The process takes place in four phases: glycolysis, pyruvate oxidation, citric acid cycle, and oxidative phosphorylation.
