Unit 4 Test Review

The table shows the classification of four mammals found in Texas. Based on this table, which explanation best describes why elk and fallow deer are classified in the same genus?

• They are both in family Cervidae and share a more recent common ancestor.

• They mate and produce fertile offspring.

• They live in similar habitats.

• They are both in kingdom Animalia and have similar diets.

The classifications of four trees are shown in the table. Which two trees are the most closely related?

• Taiwan beech and Taiwan catkin yew

• Taiwan catkin yew and lodgepole pine

• Lodgepole pine and Japanese maple

• Japanese maple and Taiwan beech

A student creates a dichotomous key to identify birds. Based on the key, which two characteristics are shared by the red-winged blackbird and the hairy woodpecker? Select TWO correct answers.

• Does not have a crest

• Is not blue

• Does not have a short beak

• Does not have reddish coloration

• Is not mostly black and white

A dichotomous key of different mollusks is shown. Which mollusk moves by jet propulsion and does not have an external shell?

• Squid

• Slug

• Nautilus

• Snail

Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms including a high fever, headaches, and body aches typically occur two to seven days after infection by the virus. SARS is more serious in elderly patients. This information suggests that the reproductive cycle of the SARS virus is —

• lysogenic, because the virus is a coronavirus

• lytic, because the virus causes respiratory illness

• lysogenic, because the virus primarily affects older people

• lytic, because of the quick onset of symptoms after infection

Some students used information they gathered from lab investigations to prepare a table. They entered the table in their lab notebooks. Which of these correctly identifies the two cells described in the table?

• 1. Cell 1 is eukaryotic, and Cell 2 is prokaryotic.

• Cell 1 is prokaryotic, and Cell 2 is eukaryotic.

• Both Cell 1 and Cell 2 are eukaryotic.

• Both Cell 1 and Cell 2 are prokaryotic.

 A table comparing the characteristics of four samples is shown. Which sample most likely contains viruses?

• Sample 1

• Sample 2

• Sample 3

• Sample 4

A diagram of an HIV infection is shown. Which conclusion about the HIV infection of a host cell is best supported by the diagram?

• It takes place outside of living cells.

• It relies on the host cell to reproduce.

• It involves the process of meiosis.

• It requires carbon dioxide.

Which characteristic do all organisms in Kingdoms Animalia, Protista, and Fungi have in common?

• They are eukaryotic.

• They are prokaryotic.

• They are unicellular.

• They are multicellular.

Models of the human immunodeficiency virus (HIV) and an animal cell are shown below. What is the difference in the function of the glycoprotein structures of an HIV virion and the cilia of an animal cell?

• The glycoprotein structures are used for attachment, and the cilia are used to move fluids surrounding the cell.

• The glycoprotein structures are used to obtain nutrition, and the cilia are used to secrete proteins.

• The glycoprotein structures are used to provide physical support for the viral envelope, and the cilia strengthen the cell membrane.

• The glycoprotein structures are used for defense, and the cilia are used for locomotion.
