The assumption in this problem is that the gas, CO2, is ideal and that the ideal gas law is applicable such that,
n = PV/RT
We simply substitute the given values to the equation above,
n = (1 atm)(V) / (0.082 Latm/mol.K)(T)
n = 12.20 V/T

Answer: It will slow down.
Explanation: This is because the same amount of blood that usually goes through will have to fit through a blocked vessel. Only a little will be able to go through at one time, causing the blood flow on the other side to slow.
(That is really dangerous. The build-up will eventually burst the vessel) Just an FYI
Answer:
Option C
Explanation:
The null hypothesis is the problem statement and alternative hypothesis is counter of the null hypothesis.
Hence, the null hypothesis here is the rate of extinction was neither higher nor lower when there were sudden climatic changes (asteroid strike)
And alternate hypothesis is "the rate of extinction was either higher or lower when there were sudden climatic changes (asteroid strike)"
Hence, option C is correct
