Concept explainers
To determine:
The type of muscle that assists an agonist either by causing a like movement or by providing the stability to the joint on which agonist acts upon is:
(a) Antagonist
(b) Prime mover
(c) Synergist
(d) Agonist
Answer to Problem 1RQ
Solution:
(c) Synergist: The term “synergist” refers to the working together of two or more components. Similarly, the combined effect thus generated is referred to as the synergistic effect.
Explanation of Solution
An agonist is a muscle that is responsible for generating a specific movement. It might also be referred to as the prime mover, for example, the pectoralis muscle. Synergists help the agonist or the prime mover in completing its movement by aiding a small amount offorce or avoiding the movements that are not necessary.

Explain whether predators and scavengers are necessary or beneficial for an ecosystem.arrow_forwardmagine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different.
