Biology Unit 4 - RETEST

Blue jays and kingbirds are both classified in the same order. This means that the two types of birds must also belong to the same

• Phylum

• Family

• Genus

• Species

The table provides classification information for four different mammals.

Which of these mammals are most closely related to each other?

• 1 and 2

• 1 and 3

• 2 and 4

• 3 and 4

What is the difference between the full classification of organisms and their scientific names?

• The full classification of organisms will include more taxa than their scientific names.

• The full classification of organisms and their scientific names vary in different countries

• The scientific names of organisms include the order and the family of the organisms, but the full classification only includes the species name.

• The full classification of organisms and their scientific name are the same.

What is the best explanation for the continual changes in the classification system of organisms?

• All organisms struggle for existence and become extinct.

• Technological advances have allowed scientists to better compare organisms.

• All organisms compete to be at the top of the food chain.

• More species have been discovered, but scientists have not analyzed all of the data

A certain organism has many cells, each containing a nucleus. If the organism can make its own food, it would be classified as

• A bacterium

• A fungus

• A plant

• An animal

Which of the following is an example of a prokaryotic organism?

• A bacterium

• A fungus

• A plant

• An animal

Organism A is eukaryotic, unicellular, and lacks a cell wall. Organism B is eukaryotic, multicellular, and contains chloroplasts. In which kingdom should these organisms be classified?

• Organism A is a protist, and organism B is a fungus.

• Organism A is a protist, and organism B is a plant.

• Organism A is an animal, and organism B is a fungus.

• Organism A is an animal, and organism B is a plant.

The table provides information about nutrition and cellular structure for organisms in different kingdoms.

What information best completes the table?

• Autotrophic, no, unicellular

• Autotrophic, yes, multicellular

• Heterotrophic, no, unicellular

• Heterotrophic, yes, multicellular

Which statement about plant and animal cells is true?

• Plant cells have a nucleus and a cell wall; animal cells do not have either of these structures.

• Plant cells have a cell wall and chloroplasts; animal cells do not have either of these structures.

• Plant cells have a cell wall and a cell membrane; animal cells have a cell wall but not a cell membrane.

• Plant cells have chloroplasts and mitochondria; animal cells have chloroplasts but do not have mitochondria.

• Have a nucleus

• Have ribosomes

• Have DNA

• Have cytoplasm
