navik [9.2K]

Answer:

A. The muscle would not contract.

Explanation:

The sarcoplasmic reticulum is a specialized smooth endoplasmic reticulum that transmits electrical impulses and is the primary regulator of calcium storage, release, and reuptake. On the other hand, glycolysis and the mitochondria are responsible for cellular ATP production.

In the muscle, the SR and mitochondrial function are interconnected, ATP is used to lower myoplasmic calcium levels during muscle relaxation, this means that muscle contractility is linked to the control of sarcomeric Ca2+ delivery/removal and ATP generation/utilization.<em> If we have a failure to remove Ca2+ from the cytosol by not producing ATP, the muscle will be prevented from relaxation, subsequently there will be a decrease in muscle contraction too.</em>

I hope you find this information useful and interesting! Good luck!

A 200.-milliliter sample of CO2(g) is placed in a sealed, rigid cylinder with a movable piston at 296 K and 101.3 kPa. Determine
bagirrra123 [75]

Answer:

The final volume of the sample of gas V_{2} = 0.000151 m^{3}

Explanation:

Initial volume V_{1} = 200 ml = 0.0002 m^{3}

Initial temperature T_{1} = 296 K

Initial pressure P_{1} = 101.3 K pa

Final temperature T_{2} = 336 K

Final pressure P_{2} =  K pa

Relation between P , V & T is given by

P_{1} \frac{V_{1} }{T_{1} } = P_{2} \frac{V_{2} }{T_{2} }

Put all the values in the above equation we get

101.3 (\frac{0.0002}{296} )= 152 (\frac{V_{2} }{336} )

V_{2} = 0.000151 m^{3}

This is the final volume of the sample of gas.

Greater than ___________ mcg/dl is considered a high level of morning cortisol.
Natalija [7]

Greater than 23mcg/dl is considered a high level of morning cortisol.

Normally, cortisol levels rise during the early morning hours and are highest about 7AM. They drop very low in the evening and during the early phase of sleep. If you do not have this daily change (diurnal rhythm) in cortisol levels, you may have overactive adrenal glands. This condition is called Cushing's syndrome.
