Answer:
The different skeletal muscle fiber types vary in the speed and duration of their twitches due to -
b) They vary in the rate of hydrolysis of ATP
c) They vary in the removal of Ca+ from the cytosol
Explanation:
There are mainly two types of muscle fibers , i.e.
a) slow twitching, long contraction duration( type I fibers)
b) First twitching but short duration of contraction. ( type II fibers).
Now think of the physiology of muscle. Two components are important, cytosolic Ca++ concentration and Availability of ATP. K+ is related to the action potential ( none or all law, there is no relation to the duration with respect to the potassium). For long contraction muscle fibers need a more steady supply of ATP, and also consistent high concentration of cytosolic Ca++ for muscle contraction to happen. So, these two factor is important for the duration of twitching. So the answer is option f .
Answer:
Bernice is having <u>night sweats</u>, which is a form of <u>hot flash.</u>
Explanation:
Night sweats refers to the relatively harmless but excessive sweating while sleeping. It can be caused due to a infection, medical condition or underlying disease. It is a form of severe hot flashes that occur at night and can cause the person to get drenched due to excessive sweating while sleeping.
This condition can be commonly seen in women above the age of 40, due to hormonal imbalance caused due to perimenopause or menopause.
<u>Therefore, Bernice is having </u><u>night sweats</u><u>, which is a form of </u><u>hot flash. </u>
Hopefully this is right:
Comes in through superior and inferior vena cava, then enters right atrium, then tricuspid valve and into the right ventricle. Then the deoxygenated blood gets pumped through the pulmonary artery to the lungs. Oxygenated blood comes back through pulmonary vein and into left atrium. Then goes through mitral valve and into left ventricle which then pumps the blood through aorta.
