Answer: The correct answer is A. 11.5 atm. The temperature is held constant at 293 K, therefore, we can use Boyle's Law to determine the initial pressure. Boyle's Law states that there is an inverse relationship between pressure and volume of gases. Therefore, as volume increases, the pressure will decrease and vice versa.
Further Explanation:
Boyle's Law can be mathematically expressed as:

In this problem, we are given the values:
P(initial) = ?
V(initial) = 80 L
P (final) = 0.46 atm
V (final) = 2000 L
Plugging in these values into the equation:

The initial pressure was 11.5 atm. Since the volume increased or expanded, the space where the gas particles move is bigger, so the frequency of collisions with the wall of the container and with other particles are effectively decreased. This, therefore, decreases the pressure from 11.5 to 0.46 atm.

Answer: An increase in the ratio of insulin to glucagon will increase the activity of --
- Acetyl-CoA carboxylase(+)
-Phosphofructokinase PFK2(+)
-Glycogen synthase(+)
- Hormone sensitive lipase (-). The hormone sensitive lipase activity is not increased with increased insulin activity.
Explanation: increased insulin - glucagon ratio is usually high in fed state.Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.
Answer:
A working model used to test a design is called a
stop
Within the categories of homogeneous and heterogeneous mixtures there are more specific types of mixturesincluding solutions, alloys, suspensions, and colloids. A solutionis a mixture where one of the substances dissolves in the other. The substance that dissolves is called the solute.
