Summary Introduction
Introduction:
The system of leads in an electrocardiogram monitors the electrical activities of the heart. The leads are both unipolar and bipolar. The unipolar leads consist of one electrode at one end and one neutral electrode. These leads monitor the electrical activity between the positive electrode and the reference point at the center of the heart, which has zero electrical references. The bipolar leads consist of positive and negative electrodes. The frontal plane activity is monitored by the limb leads. The frontal plane activity involves the flow of electrical waves over the anterior surface of the heart.

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?

- 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.
