Summary Introduction

Introduction:

Muscle has defined a type of soft tissue found in animals and humans. There are three types of muscles such as striated muscle, non-striated, and cardiac muscle. It is composed of actin and myosin protein filaments that slide into one another and caused contraction of the muscle. It helps to produce force and motion.

Answer to Problem 1DYKB

Correct answer:

Agonist is the primary muscle that produces movement. Therefore, option b. is correct.

Explanation of Solution

Reason for the correct statement:

Option b. is given as “It is the primary muscle that produces a movement”. Agonist is also called a prime mover. This muscle contracts primarily to produce particular movement such as extending the forearm. So, this muscle initiates movement.

Hence, option b. is correct.

Reasons for the incorrect statements:

Option a. is given as “It opposes the function of the prime mover”. Antagonist muscle is a type of muscle that opposes function of the prime mover. Hence, option a. is incorrect

Option c. is given as “Its function primarily to stabilize the joint”. Antagonist stabilizes the joint. Hence, option c. is incorrect.

Option d. is given as “Its muscle fibers are always circular in structure”. Agonist is a type of muscle which only provides shape to muscle. Hence, option d. is incorrect.

Hence, options a., c., and d. are incorrect.

Conclusion

Agonist is a muscle and is also called prime mover as it contracts to initiate the movement of muscles.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)   Data Table 1Stage    Totals    PercentInterphase        Mitosis:        Prophase        Metaphase        Anaphase        Telophase        Cytokinesis        Totals    100    100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours.
