Back

Messenger RNA

Front

Brings the appropriate amino acids to the ribosome in the correct order to assemble the protein chain.

Back

Transfer RNA

Front

A structural component where protein synthesis takes place.

Actin is a protein that helps the cell maintain its shape and polarity. It also plays a major role in muscle contraction. Based on this information, actin is most likely —
Options: an enzyme protein, a structural protein, a messenger protein, a transport protein

Back

a structural protein

Which portion of the label provides information about the amount of quick energy in a drink? Options: Calories, Total Fat, Sodium, Total Carb, Protein.

Back

Total Carb

Front

Which statement accurately compares eukaryotic cells and prokaryotic cells?

Back

Eukaryotic cells are more complex than prokaryotic cells.

Front

In animal cells, the sodium-potassium pump moves sodium and potassium ions against a concentration gradient across the cell membrane. What type of transport is used, AND why is this type of transport necessary?

Back

Active transport; it requires energy to move ions against the gradient.

Front

The diagram represents the movement of three different substances across a cell membrane. Moving which of these substances across the cell membrane requires energy from ATP?

Back

3 only

Front

A student claims that the influenza virus replicates in the air and then infects people. Which statement BEST describes the claim? Options: The claim is true because viruses can infect cells without direct contact., The claim is true because viruses replicate within the particles of the air., The claim is false because viruses require host cells in order to replicate., The claim is false because viruses cannot survive in the air.

Back

The claim is false because viruses require host cells in order to replicate.

Front

Which correctly describes the lytic and lysogenic cycles?

Back

Lytic: A bacteriophage reproduces inside a host cell and releases bacteriophages when the host cell bursts.
Lysogenic: A bacteriophage inserts its viral genome into a host cell's genome.
