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:
The correct answer is left cerebral hemisphere.
Explanation:
The left cerebral hemisphere of the brain is accountable for the motor control of the right side of the body, for sensory stimulus from the body’s right side, for analysis and calculations, for the speech, comprehension, and language, for the recognition of letters, words, and numbers, and for time and sequencing.
The left cerebral hemisphere is accountable for the processing of the sensory information and motor information for the body’s right side. Thus, as left cerebral hemisphere monitors the movement of the body's right side, so, based on the extremity of the stroke, which may result in motor skill impairment or functional loss of the right side of the body, shows that the left side of the brain has got affected.
The client who complain of felling dizzy and light headed and having tingling sensation of fingertips around the lip is related to hyperventilation.
Hyperventilation of the client is associated with client blowing excessive carbon dioxide which lead to client fell dizzy and light headed and having tingling sensations of the finger tip around the lips If this condition is uninterrupted it could lead to respiratory alkalosis.
Answer:
The nuclear reaction rate is very sensitive to temperature so that even a slight increase in temperature makes the nuclear reactions occur at a MUCH higher rate. This means that a star's luminosity increases a lot if the temperature is higher.
