Smooth muscles depolarize as a result of a transmembrane current of Calcium ions. When an action potential depolarizes the muscle cell membrane, it also travels into the body of the cell via the t-tubules. Unlike skeletal muscle, smooth muscle is dependent in two sources of calcium in order to intiate contraction. These two sources are calcium sequestered in the S.R. of the smooth muscle cell.
Answer:
D) Folded mountain with jagged, rough edges
Explanation:
The incident which happened some fifty million years ago was the collision of the Indian plates and the Eurasian plates thus giving rise to the folded mountains that are characteristic of the Himalayas. Subduction was not possible when these two plates collided because they had the same density.
So, the force with which the two plates collided resulted in the formation of folded mountains that rose upward. The peaks of these mountains were jagged, rough, and uneven.
Atoms come together to form molecules because of their electrons. Electrons can join (or bond) atoms together in two main ways. When two atoms share electrons between them, they are locked together (bonded) by that sharing. These are called covalent bonds
