A) a larger number of offspring
B) more genetic variation among their offspring
C) offspring that are nearly identical to their parents
D) offspring that are perfectly adapted to their parents' habitat
2. X --> Y + Z + energy
The equation above represents a nuclear decay, in which nucleus X decays into particle Y and nucleus Z and releases energy. Which of the following can explain why energy is released in the decay?
A) The mass of X is less than the sum of the masses of
Y and Z.
B) The mass of X is less than the difference between the masses of Y and Z.
C) The mass of X is greater than the sum of the masses of
Y and Z.
D) The mass of X is greater than the difference between the masses of Y and Z.
3. Air in the atmosphere continuously moves by convection. At the equator, air rises; at the poles, it sinks. This occurs because
A) the Earth's ozone layer is thinner at the equator than
at the poles
B) the Earth's magnetic field is stronger at the poles than
at the equator
C) warm air can hold less water vapor than can cold air
D) warm air is less dense than cold air
Without CHEATING, leave your answers in a comment. I'll post the correct answers later.
Just remember if you cheat and google the answers then you're just a plain ol' idiot, but if you don't know then it just means that you haven't learned enough yet.
