<span>This change in scientific consensus happened
because scientists liked the idea that T. rex held its tail aloft
better.
- no, this is not a scientific behaviour!
no one supported the idea that T. rex dragged its tail on the
ground.
- this is not true, someone must have supported it if people believed it
the idea that T. rex held its tail aloft is an emerging idea
that replaced the old idea.
- yes, but how did the new idea come about?
the idea that T. rex held its tail aloft was

Answer:
Option A, Hormones are controlled by a feedback loop; information about a system is sent back to the controller of the system to improve its function.
Explanation:
Negative feedback loop controls the hormone production and release. This is done by eliciting the release of substances till a certain level after which the stop signal is activated thereby preventing further release. By this method, concentration of hormones in blood is maintained within the narrow range.
For example – Thyroid hormones is released when the anterior pituitary signals the thyroid. This continues till the hormones in the blood reach the threshold level. Once the threshold level is reached, hypothalamus receives a feedback and then signals anterior pituitary to inhibit further signaling to the thyroid
Hence, option A is correct
Answer:
Over population
Explanation:
With the coyotes gone, they're prey will have little to no predators. Without their numbers decreasing as quickly (because of the coyote population drop) they will be able to repopulate quicker and less of them will die. This will lead to over population.
