Question
Chapter 10, Problem 15CP
Summary Introduction
To review:
The way in which the size of the motor units controls the degree of muscular movement.
Introduction:
A motor unit consists of a motor neuron and multiple muscle fibers innervated by the axonal terminals of the motor neuron. This combination brings about stimulation or contraction of a number of fibers by a single motor neuron.

What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.
How would increased estrogen affect the river otter population?
Based on your reading of the materials in this unit, what factors can affect fertility in humans?
Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.

- magine 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.
