Its an evolutionary theory that explains the origin of <span>eukaryotic and </span>prokaryotic cells.
The answer is B. Genetic drift greatly affects small populations, but large populations can recover.
Answer:
D) vascular plants
Explanation:
It would most likely be vascular plants based on the sentence regarding large algae. Vascualr plants are more complex than algae, and mammal species is quite a large step up from the simple algae. The answer of marine animals follows the same logic. Life to land could be a probalbe answer, but that involves many vascular plants that could live under the water.
Answer:
0.36g
Explanation:
Given parameters and conversion to standard unit
To solve this problem we must assume ideality
Volume of N₂H₄ = 350mL = 0.35dm³
Temperature of container = 50°C = 50 + 273 = 323K
Pressure = 885torr;
760torr = 1atm
885torr = = 0.86atm
Unknown:
Mass of the compound = ?
Solution:
The mass of the compound can be derived using the expression below;
Mass = number of moles x molar mass
molar mass of N₂H₄ = 2(14) + 4(1) = 32g/mol
To find the number of moles;
PV = nRT
n =
P is the pressure
V is the volume
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = = 0.01mole
So,
Mass = 0.01 x 32 = 0.36g
