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 .
Please be rightly informed that different research laboratories have different ways of measuring impulsivity simply because respective research centres have different means of measuring the impulsivity of drugs or substances.
<h3>Research laboratory</h3>
A research laboratory is simply a testing center where scientific investigation, observations and experimental analysis are made.
A research laboratory must be free of biase Informations and results given by research centres must be verifiable by other centers
So therefore, please be rightly informed that different research laboratories have different ways of measuring impulsivity simply because respective research centres have different means of measuring the impulsivity of drugs or substances.

Answer: True
Explanation:
The cardiovascular system includes the heart and blood vessels. The function of the heart is to pump out oxygenated blood via blood vessels to all the parts of the body. The blood vessels arteries, veins and capillaries contribute to the transfer and distribution of the blood.

Explanation:
They might lose control and fall or get injured some other way.
A penetrating abdominal injury with severe respiratory distress has most likely involved Diaphragm.
What is the penetrating abdominal injury ?
Penetrating stomach injuries to the thorax: a wound that enters above the costal border, below the fifth intercostal gap. These wounds have the potential to have started in the chest before moving through the diaphragm and into the abdomen.
What organ sustains damage the most frequently when the abdomen is penetrated?
The following organs are the most frequently injured in abdominal injuries caused by stab wounds: Liver (40%) Small intestine (30%) Diaphragm (20%)
Diaphragmatic injuries are quite uncommon and are brought on by either penetrating or blunt trauma. 1-7% of patients who sustain significant blunt trauma and 10-15% of patients who sustain penetrating trauma to the lower chest experience traumatic diaphragmatic rupture.
