The characteristics of a particular organism are listed below.

• Is unicellular • Has cell nuclei • Lives in moist environments • Reproduces asexually • Is mobile

In which kingdom should this organism be classified?

• Eubacteria

• Animalia

• Plantae

• Protista

An organism is unicellular, reproduces asexually, and lives in a hot hydrothermal vent at the bottom of the ocean. This organism most likely belongs to the kingdom —

• Eubacteria.

• Animalia.

• Archaea.

• Protista.

What characteristic distinguishes members of the kingdom Plantae from members of the kingdom Fungi?

• All plants are organisms composed of many cells, whereas all fungi are organisms composed of only one cell.

• Plants are prokaryotic; fungi are eukaryotic.

• Plants are producers; fungi are decomposers.

• All plants are organisms that reproduce sexually, whereas all fungi are organisms that reproduce asexually.

What is the most basic difference between autotrophs and heterotrophs?

• Heterotrophs remain in one place, while autotrophs move around.

• Heterotrophs get nutrition by eating, while autotrophs make their own food.

• Heterotrophs respond to their surroundings, while autotrophs do not.

• Heterotrophs excrete waste products, while autotrophs do not.

How do scientists classify the millions of organisms on Earth?

• By placing them into a hierarchical system based on shared traits and characteristics

• By placing them into an alphabetical system based on the discovering scientist

• By placing them into a system based on population size and location

• By placing them into a chronological system based on date of discovery

The pictures show a humpback whale, weighing a massive 140 million grams, and a pygmy shrew, weighing 4 grams. Are these two vastly different organisms classified in the same domain or kingdom?

• They are classified into the same domain, but they are in different kingdoms.

• They are classified into different domains, but they are the same kingdom.

• They are classified into the same domain and same kingdom.

• They are classified into different domains and kingdoms.
