Animal Review

A clown fish uses its gills to filter oxygen from the water.

Which process does this represent?

• ability to move and explore its environment

• ability to reproduce

• ability to obtain resources

• ability to grow and develop

A student observes a group of animals that are the same species; however, they seem to have different characteristics, as noted below:

1. All of the animals are ectothermic.

2. Some of the animals have gills and are swimming.

3. Some of the other animals have lungs and are walking on land.

What type of animal is she most likely observing?

• Fish

• Amphibians

• Reptiles

• Birds

A student has discovered an unknown organism. Below is a list of its characteristics:

1. jointed legs

2. segmented bodies

3. an exoskeleton

Which group of animals does this organism most likely belong

• Mollusk

• Echinoderm

• Arthropod

• Segmented Worm

Consider the following information about crows:

1. Crows eat a variety of foods, including nuts, insects, and plants.

2. Most crows build nests in trees from sticks, bark and animal fur.

3. Most crows mate during spring.

4. Some crows crack nuts by dropping them in front of moving cars.

Which of these is a conditioned behavior?

• Eating plants and insects

• Building nests in trees

• Mating in the spring

• Dropping nuts in front of cars

The chart below describes four different sets of observations.

Which of the columns of observations contains a non-living object?

• Column A

• Column B

• Column C

• Column D

The chart below shows the classification of four animals.

Which two animals would most likely breed to produce the same kind of offspring?

• Animals B and C because they are the same family.

• Animals A and D because they are the same class.

• Animals A and D because they are the same species.

• Animals B and C because they are the same genus.

The chart below shows some of the levels of classification for an organism.

 Levels of Classification

Kingdom Animalia

Phylum Arthropoda (Invertebrate)

Class Insecta

Order Hemiptera

Family Cimicoidae

 Which picture best represents the type of organism described in the chart?

•

Sue is studying characteristics of vertebrates and invertebrates.  She wants to organize her information into a Venn diagram, as shown below.

Which characteristic(s) is a similarity between vertebrates and invertebrates that should be added to the middle of the Venn diagram?

• Both require food and oxygen to survive.

• Both maintain a constant body-temperature.

• Both have arms extending from the center of their body.

• Both have an internal skeleton for support.

The evolution of the elephant began almost 55 million years ago. It is believed that the early ancestor of the modern elephant was the size of a pig and had a mobile upper lip similar to a tapir which uses their long snout to easily forage along the ground in search of food. Eventually, this early ancestor grew taller, and the mouth grew into a longer shovel-like mouth. The modern day elephant with its long trunk evolved from this ancestor. This progression can be visualized in the illustration below.

The modern day elephant with its long trunk evolved from this ancestor. This progression can be visualized in the illustration below.

What is the best claim and reasoning for the development of the elephant's trunk?

• As the elephant grew in size over time, its heart became bigger. This extreme force from blood flow caused the mouth to grow into a trunk.

• The trunk evolved to aid in elephant camouflage and protection from predators.

• With the development of longer limbs, a longer trunk evolved which was more useful for gathering food.

• With the use of elephants in the entertainment industry, elephants with longer trunks were selected more often.

Below are drawings of different birds. 

Why do these birds have different shaped beaks? 

• as an adaptation to escape different predators

• as an adaptation to obtain different food

• as an adaptation to move different ways

• as an adaptation to build different habitats
