The class iv calcium blocker that exclusively administered to treat acute supraventricular tachyxardia is Diltiazem. Calcium channel blockers obstruct the movement of calcium into conductive and contractile myocardial cells by inhibiting the influx of calcium through its channels, causing a slower conduction through the SA and AV. Diltiazem is administered intravenously to treat acute supraventricular tachycardia.
The change in internal energy of this gas sample is equal to: c. 715 J.
<u>Given the following data:</u>
- Quantity of heat = 874 J.
<h3>What is the First Law of Thermodynamics?</h3>
Mathematically, the the First Law of Thermodynamics is given by this formula:

Where;
is the change in internal energy.
- Q is the quantity of heat.
Substituting the parameters into the formula, we have;

Change in internal energy (ΔH) = 715 Joules.

Answer:
An important cell cycle control mechanism activated during this period (G1 Checkpoint) ensures that everything is ready for DNA synthesis. ... DNA replication occurs during this S (synthesis) phase. Gap 2 (G2): During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins.
