Exclusively breastfed babies do not require additional water even when it is very hot outside, as long as baby is allowed to nurse as needed. Even in extremely hot, dry weather your baby can get all the liquids needed via breastmilk.
Smooth muscles contract very slowly, whereas skeletal muscles can contract at different rates. Skeletal muscles can be composed of fast-contracting fibers, slow-contracting fibers or a mixture of both.
Answers. Best Answer: skeletal and cardiac muscle cells are striated which means that there is overlap between actin and myosin filaments. there is also a high degree or organization of these filaments into sarcomeres.smooth muscle cells have no such striations and the cells are spindle-shaped.smooth muscle cells contract slower and for longer periods of time (think of the intestines).ardiac muscle cells also have intercalated discs that allow for rapid propagation of impulses. skeletal muscles contract much faster than cardiac muscle cells and also have a shorter refractory period. as a result of a longer refractory period, cardiac muscle cells cannot show wave summation and tetany.
