How do convection currents in the atmosphere form? A Warming air expands, becomes denser, and sinks. As the air sinks, it displaces cooler, less dense air which rises
B Warming air expands, becomes less dense, and rises. As the air rises, it pushes cooler, more dense air down
C Cooling air contracts, becomes denser, and sinks. As the air sinks, it displaces warmer, more dense air which rises
D Cooling air contracts, becomes less dense, and rises. As the air rises, it pushes warmer, more dense air down

Scientists studied reproduction in the new zealand mud snail to answer the question, “are there benefits to reproducing sexually or asexually? ” which of these hypotheses would least likely aid the scientists as they worked to answer the question? sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation. asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring. sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation. asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social
