How do hydrogen bonds between water molecules occur?

• a. The slight positive charge on an H atom of one water molecule is attracted to the slight negative charge of an O atom on another water molecule.

• b. A strong positive charge on an H atom of one water molecule is attracted to the strong negative charge of an H atom on another water molecule.

• c. There is a polar attraction between two slightly positive H atoms in two different water molecules.

Proteins are synthesized, packaged, and exported from a cell using all of the following organelles except

• a. endoplasmic reticulum.

• b. Golgi apparatus.

• c. mitochondria.

• d. ribosomes.

How is active transport different from passive transport?

• a. Both active and passive transport occur within plant cells, but only active transport occurs within animal cells.

• b. Both active and passive transport occur within animal cells, but only active transport occurs within plant cells.

• c. Passive transport uses energy to move materials across a cell membrane against a concentration gradient, while active transport moves materials across a cell membrane in the direction of a concentration gradient, without using energy.

• d. Active transport uses energy to move materials across a cell membrane against a concentration gradient, while passive transport moves materials across a cell membrane in the direction of a concentration gradient, without using energy.

• b. Recommend making antibiotics available for individuals to use as they wish.
