Which MOST closely defines population density?
2 answers:
Answer: Option (A) is the correct answer.
Explanation:
Usually, density is defined as mass present in per unit volume.
Mathematically, Density =
Since density is directly proportional to mass so, more is the mass of an object more will be its density.
Similarly, population in terms of density is the number of organisms of a species per unit area.
Thus, we can conclude that out of the given options the number of organisms of a species per unit area MOST closely defines population density.

Answer:
After the transfer the pressure inside the 20 L vessel is 0.6 atm.
Explanation:
Considering O2 as an ideal gas, it is at an initial state (1) with V1 = 3L and P1 = 4 atm. And a final state (2) with V2 = 20L. The temperature remain constant at all the process, thus here applies the Boyle-Mariotte law. This law establishes that at a constant temperature an ideal gas the relationship between pressure and volume remain constant at all time:
Therefore, for this problem the step by step explanation is:
Clearing P2 and replacing
