Negative feedback mechanisms act to correct deviations from a normal range within the internal environment

True

In a negative feedback loop, the effector produces changes that are

opposite in direction to the change produced by the initial stimulus

A hormone called parathyroid hormone acts to help raise the blood calcium concentration. According to the principles of negative feedback, an effective stimulus for parathyroid hormone secretion would be

1. a fall in blood calcium.

what consists of dense, parallel arrangement of collagen fibers

Tendons

The act of breathing raises the blood oxygen levels, lowers the blood carbon dioxide concentration, and raise the blood pH according to the principles of negative feedback sensors that regulate breathing should respond to

A rise in blood carbon dioxide concentration
