Chapter 30, Problem 1CC

Complete this concept map on animal movement.

Summary Introduction

To complete: The given map showing the animal movement.

Introduction:

Movement is a distinguishing characteristic of animals. Even animals that are attached to a substrate move their body parts. All types of animal movement have underlying similarities. At the cellular level, every form of movement involves protein strands moving against one another, an energy-consuming process.

Explanation of Solution

Pictorial representation:

Fig. 1 shows the completed map of the animal movement.

(a)

Correct answer: Skeleton.

Movement in animals requires both the skeleton as well as the muscle. There are many types of skeletons present among the various organisms, which include the endoskeleton, exoskeleton, and hydrostatic skeleton. Each skeleton is associated with different types of movement, such as, flying, walking, running, crawling, and others. Hence, the correct answer is skeleton.

(b)

Correct answer: Muscles.

In every organism, muscles are required to generate a required amount of energy, whether walking, running, swimming, or flying. Hence, the correct answer is muscles.

(c)

Correct answer: Exoskeleton.

The skeletons found among the diverse group of organisms are categorized into three types, which include the endoskeleton, hydrostatic skeleton, and exoskeleton. The exoskeleton is primarily found in the insects. Hence, the correct answer is exoskeleton.

(d)

Correct answer: Sarcomere.

Sarcomeres are the units of muscle contraction; they are found in the striated muscles and are present between 2-Z lines as a repeating unit. Hence, the correct answer is sarcomere.

(e)

Correct answer: Bones and Cartilages.

Endoskeletons are present inside the body and made up of bones and cartilages. Usually, all the vertebrates have a skeleton type as an endoskeleton. Hence, the correct answer is bones and cartilages.
