The red blood cell does not have a nucleus. The lack of nucleus enables the rbc to have more room to contain hemoglobin which increases it's efficiency to carrying oxygen
Oxygen and Hydrogen Atoms!
There are five characteristics of Muscles; namely Responsiveness, Conductivity, Contractibility, Extensibility and elasticity.
Assigning each example to the universal muscle characteristic being described;
Conductivity; (electrically stimulating a muscle) Local electrical change triggers a wave of excitation that travels along the muscle fiber.
Contractibility; Shortens when stimulated
Elasticity; Returns to its original resting length after being stretched,
Extensibility; capable of being stretched between contractions.
Responsiveness; to chemical signals, stretch, and electrical changes across the plasma membrane.
Answer:
B)
Explanation:
The more force the swimmer applies back on the wall, the faster his movement forward in the water. Newton's third law states that for every action there is an equal and opposite reaction. Not all the statements are false; they just do not describe Newton's throw law of motion.
