Multiple Choice

A student produces a labeled drawing of a virus for a presentation. The student states that the capsid has a function similar to the nuclear membrane found in animal cells.

Which of these describes the similar functions of capsids and nuclear membranes?

• Both transport proteins throughout the structures.

• Both provide energy for activities in the structures.

• Both protect genetic information for the structures.

• Both code for the proteins needed for reproduction of the structures.

Multiple Choice

An illness caused by a certain virus includes fever, rash, joint pain, red eyes, and headache. The virus is transmitted to people by infected mosquitoes. Symptoms quickly occur within three to twelve days after contracting the virus. There is no vaccine for this virus. Which description best explains the reproductive cycle of this virus?

• Lytic, because the virus is transmitted by mosquitoes

• Lysogenic, because there is no way to vaccinate against it

• Lytic, because of the quick incubation time

• Lysogenic, because the virus causes a fever

Multiple Choice

Which of these describes a difference between viruses and cells?

• Cells contain protein, and viruses contain only carbohydrates.

• Viruses have flagella, and cells have only cilia.

• Cells reproduce independently, and viruses require a host to reproduce.

• Viruses have membranes made of proteins, and cells have membranes made of nucleic acid.
