Answer:
<em>True.</em>
Explanation:
<em>As a river develops bends, called meanders, it forms a broad, flat area known as a floodplain. At the end of a stream, a delta or an alluvial fan might form where the river drops off much of the load of sediments it carries. Caves form underground as groundwater gradually dissolves away rock.</em>

Explanation:
Answer:
Contractile activity of smooth-muscle cells does not normally require Ca2+.
Explanation:
There is deficiency of Smooth striations characteristic of cardiac and skeletal muscle in smooth muscle. Different organs and tube were lined with layer of Smooth muscle cell, though for contraction of Smooth muscle to occur, it's not a voluntary control
THE CONTRACTILE PROCESS
In the body of organism, the process of smooth muscle cell contraction is regulated through the activities of receptor and mechanical activation of myosin and actin which are reffered to as contractile proteins.
During the contraction process, myosin light chain kinase will phosphorylate the 20-kDa light chain of myosin, which will make the myosin to interact molecularly with actin to release Energy(ATPase). The Energy released is used for cycling of myocin and actin for contraction to take place.
Therefore,Contractile activity of smooth-muscle cells does not normally require Ca2+.
kinetic energy is needed by the molecules in order to escape from the surface.
All the water molecules in the liquid are moving randomly due to the presence of some energy in it. Some of the molecules have more kinetic energy due to absorption of heat energy from the surrounding environment.
Due to high kinetic energy, these molecules move enough to escape the surface of the liquid. This is called boiling point. This makes the liquid become gas so we can conclude that kinetic energy is needed by the molecules in order to escape from the surface.
