Answer:
help the digestive system break down food quickly
Answer:
Option (A).
Explanation:
Muscle contraction may be defined as the physiological process of the activation of tension generating sites that occur within the muscle fibers. Actin, myosin, troponin and other proteins are important for muscle contraction.
The calcium ion is important for the muscle contraction. The binding of calcium with troponin causes the movement of tropomyosin out of the grooves between the actin molecules during muscle contraction.
Thus, the correct answer is option (A).
Sediments are loose Earth<span> materials such as </span>sand<span> that accumulate on the land surface, in river and </span>lake<span> beds, and on the </span>ocean<span> floor. Sediments form by </span>weathering<span> of rock. They then erode from the site of weathering and are transported by </span>wind<span>, </span>water<span>, </span>ice<span>, and </span>mass wasting<span>, all operating under the influence of gravity. Eventually sediment settles out and accumulates after transport; this process is known as deposition. Sedimentation is a general term for the processes of </span>erosion, transport, and deposition. Sedimentology is the study of sediments and sedimentation.<span>
