How are DNA and RNA different? A) DNA has a single chain and the base thymine, while RNA has a double chain and the base cytosine instead or uracil.
B) DNA has deoxyribose sugar and 4 bases while RNA has ribose sugar and only two bases.
C) DNA has double chains, deoxyribose sugar, and thymine while RNA has a single chain, ribose sugar, and uracil.
D) RNA is found in the nucleus of the cell and DNA is found in the cytoplasm of the cell.

Which best explains how a heat pump can heat a room? cold air from the house is moved through pipes, where it absorbs thermal energy. warm air from outside is pushed into the house to replace the cold air. combustion warms the air when chemical energy is transferred to thermal energy. fuel is used to move a piston, which pushes warm air into the house.

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
