Bridget Bishop was the first person to be tried, found guilty, and hung on June 10, despite the fact that she was completely innocent. Bridget was well-known across the Salem area for her un-Puritan behavior, which included wearing showy clothing, frequenting taverns, and having many marriages. Trying to avoid being hanged, Bridget confessed her guilt and renounced her good reputation in the community in order to prevent being executed. She was judged guilty by the testimonials of a large number of townspeople (more than any other defendant) and was executed on June 10, 1692, as a result of her conviction.
A waterborne pollutant can have different effects on aquatic life depending on the nature of the pollutant. A pollutant at lower levels can have minimal or no effect on aquatic life. However, when the concentrations of the pollutant are high, the population of aquatic organisms can be greatly reduced. There are also times when pollutants at lower concentrations cause significant damage. An organism can consume another organism that has absorbed small amounts of the pollutant. As the consumer takes in more of the contaminated organism, the pollutant is magnified in the body of the consumer resulting in lethal concentrations. This is called biomagnification.
The answer is;
helps decrease blood
calcium
inhibits osteoclast activity
Osteoblast activity
is inhibited so that calcium resorption from the bone is repressed.<span> Calcitonin also signals the kidneys to reduce the reabsorption of
calcium ions from urine hence increase its loss from the blood. </span>
