Plus, you can generate reward points. And credit cards can be very helpful in an emergency. That said, if an emergency does force you to carry a balance on your card, living in a financially responsible manner means curbing your spending until that balance is paid off. The same logic applies to all recurring payments that involve paying interest.
Earthworm-Muscular System. The earthworm has two muscles which it uses for locomotion, both of which run the whole length of the worm's body. These two muscles are circular muscles and longitudinal muscles (Musurca).The longitudinal muscles are the inner layer of the muscular series and cradle the coelom, the innards of the earthworm (Noble).When the circular muscles are contracted, the diameter of the body is reduced, making the worm thin.hen the longitudinal muscles are contracted, the length of the body is reduced, making the worm short. So, if an earthworm is short and thin, which is a common reaction, both types of their muscles are contracted.
Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction, while transverse waves (in solids) are waves of alternating shear stress at right angle to the direction of propagation.
