Concept explainers
To analyze:
The meaning of the statement “a whole muscle responds to a stimuli in graded fashion” and the two ways to increase the force of contraction.
Introduction:
The muscular system is the set of muscles that are present in the body adhered to the skeletal system. The muscles are divided into several types, namely cardiac muscles which are involuntary, smooth muscles and skeletal muscles which are voluntary. The muscles of the body help in the body's movement, circulate blood through the body and helps in maintaining the posture of the body. The skeletal muscle fibers and the motor neuron collectively form the motor unit. A single muscle contraction can be due to the result of the working of several motor units together.

- Species Interactions Explain how predators, prey and scavengers interact. 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. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
