Extrafusal muscle fibers are the skeletal standard muscle fibers that are innervated by alpha motor neurons and generate tension by contracting, thereby allowing for skeletal movement. They make up the large mass of skeletal muscle tissue and are attached to bone by fibrous tissue extensions (tendons). whereas Intrafusal muscle fibers are skeletal muscle fibers that serve as specialized sensory organs (proprioceptors) that detect the amount and rate of change in length of a muscle.
I believe the correct answer from the choices listed above is the last option. If a scientist needs to know the temperature of a mixture to the nearest 0.05°C, then he would need a thermometer with <span>markings every 0.1°C. Hope this answers the question. Have a nice day.</span>
Answer:
B) difference in water density
Explanation:
The deep ocean currents are the cold ocean currents. They appear in the Arctic and Antarctic circles. As the warm ocean currents come from the low latitudes toward the high latitudes, they bring in warmer water on the surface. They start to cool off though as the near the high latitudes, so gradually they become cold ocean currents. As they become cold, the water is sinking below the less dense warmer water that is coming from behind, making a turn in the opposite direction and moving as deep ocean current toward the low latitudes. Once it reaches the low latitudes, this water will get warmer, and it will move toward the high latitudes, and the process constantly continues.
