Answer:
b. decreases
Explanation:
As the depth of the ocean increases the population of ocean creatures decreases.
At special depths organisms must be better adapted to withstand the adverse and extreme conditions of this zone.
- At depths oxygen dissolve in water is rarer.
- The pressure is very great due to the column of water above
- For organisms to thrive in these zones, they must have special adaptability that would prevent them from being destroyed in this environment.
- Therefore, organisms are rarer in this zone.

Answer:
The pressure is 0,97 atm
Explanation:
We apply Boyle Mariotte's Law, where for a certain mass of gas, at constant temperature, the pressure and volume vary inversely proportionally: P1x V1 = P2 x V2 P2= (P1 x V1)/V2
P2 = 1, 50 atm x 5, 00 L /7,74 L
P2= 0, 97 atm
At STP, it is at 273 K and 1.00 atm.
Use PV=nRT to and solve for n (number of mol of N2)
1.00 atm • 4.40L / 0.08206 Latm/molK • 273 K = 0.196 mol N2
There are two mol of N2 for every two mol of NH4NO2 (the number of mol of both are equal)
Find the molar mass of NH4NO2 = 64.1 g
Multiply the number of mol by the molar mass
0.196 mol • 64.1 = 12.6 g NH4NO2
