An ion must cross the cell membrane through active transport instead of passive transport when the ion is

• negatively charged

• carried across by a protein

• going against the concentration gradient

• too small to move independently

Which best describes the interaction between DNA and RNA during protein synthesis?

• RNA carries the code to the nucleus where DNA translates the code into a protein.

• DNA travels to the ribosome where RNA translates the code into a protein.

• RNA carries the code from DNA in the nucleus to the ribosome for protein synthesis.

• DNA travels to the cytoplasm while RNA remains in the nucleus.

Which biomolecule contains nitrogenous bases?

• Lipid

• Protein

• Nucleic acid

• Carbohydrate

A researcher is studying the damage that predators cause to the wings of butterflies? Which tools are best to use to determine the percentage of butterflies with damaged wings?

• Triple beam balance and microscope

• Hand lens and triple beam balance

• Catch net and hand lens

• Microscope and graduated cylinder

In active transport, carrier proteins

• move substances across the cell membrane without the use of ATP

• move from low concentration to high concentration by diffusion

• move small molecules through the cell membrane by osmosis

• move substances from a low concentration to high concentration through the use of energy
