Genetic variation allows for mutations to occurs where survival of the fittest occurs. This makes sure that the most adapted creatures survive and are able to pass their genes on to offspring. Thus causing evolution.
Diatoms have cell walls composed of silicon dioxide.
A. silicon dioxide.
The basic structure of a muscle fiber is comprised of actin and myosin protein chains that straddle each other in a fusiform arrangement. The actin and myosin arrays interlock and move past each other to cause contraction of the muscle. They then move back to their initial positions in relaxation. This gives muscles their elasticity and distensibility. The muscle fibers are bundled, in their 10s to 100s up into myofibrils around an endomysium. Many myofibrils are also bound up in a perimysium to form a muscle fiber.
Answer:
Option (D).
Explanation:
ATP (adenotriphosphate) molecules are considered as energy currency of the cells as molecules provide energy for various cellular functions.
The energy is stored in ATPs in two high-energy phosphate bonds, known as phosphoanhydride bonds. This stored energy is released in during hydrolysis of ATP, which involves removal of terminal phosphate groups bound the carbon backbone.
Thus, the correct answer is option (D).
Explanation:
A. Adhesion
