Answer: The physical and biological changes that confirm climate warming include the rate of retreat in glaciers around the world, the intensification of rainfall events, changes in the timing of the leafing out of plants and the arrival of spring migrant birds, and the shifting of the range of some species.
Explanation:
Body temperature control is an example of negative feedback, a process by which the body responds to a stimulus by correcting the change and bringing the body back to the original setting.
What is stimulus ?
A stimulus is a noticeable change in the internal or external environment of an organism's physical or chemical composition. Sensitivity is the capability of an organism or organ to perceive external stimuli and to respond appropriately to them.
The hypothalamus controls your body temperature in a manner similar to how a thermostat controls the temperature in your home. It does this by responding to both internal and external stimuli and making adjustments to keep your body's temperature within one or two degrees of 98.6 degrees.

Hello there!
The principle of diffusion consists in the movement of substances through a membrane from a zone with high concentration, to a zone with low concentration, until the concentration is equal on both sides of the membrane.
An example of diffusion is the process that happens when we breathe. Two substances in the body that will move based on the principles of diffusion are Carbon Dioxide and Oxygen. Carbon Dioxide will move from the bloodstream to the alveoli, and Oxygen will move from the alveoli to the bloodstream.
