Answer: false
Explanation: because it increaded in a neagitive direction.
Answer:
hydrophilic/ hydrophobic
Explanation:
Hydrophobic means to be attracted to water. Hydrophobic means to be against water. In a phospholipid bilayer, the heads point out to reach the water, but the tails stay in to stay away from the water.
Answer:The above statement is "false".
Explanation:
The following events take place during contraction-relaxation of a muscle:
•Action potential in T tubule activates voltage-sensitive receptors,which in turn trigger Ca ions release from terminal cisternae of sacroplasmic reticulum(SR) into cystol.
•Ca ions bind to troponin;troponin changes shape,removing the blocking action of tropomyosin;actin active sites is exposed.
•CONTRACTION; myosin heads alternatively attach to actin and detach,pulling the actin filaments toward the center of the sarcomere;using ATP in this process.
•removal of Ca ions by active transport into the SR after the action potential ends.
•RELAXATION occurs.Actin and myosin return back to its unbound state.
Answer: slip
Explanation:
The slip may occur while working on surfaces that are slippery because of wet and oily processes occurring at the workplace. The practices like floor cleaning, debris left on the floor and leakage of material can cause slips. The slip will occur when the floor provides a limited friction for walking.
The trip may occur while walking on the uneven floor. This may occur when the person's foot hit the objects that come in contact while walking. This disturbs the balance of the person while walking.
The slip and trip both can result in fall. This happens when the body gets deviated from the center of balance.
According to the given situation, a slip will occur as the working conditions are wet and the grates on the floor will slip due to lack of friction between the floor and the grates.
