Heat transfer means heat energy is transferred from on object or a body to another. This causes change in many factors, and temperature is one of such factors. If the temperature increases, it means heating is taking place and if temperature decreases it means cooling is taking place.
If Tfinal is more than Tinitial, it means the object has gained some amount of heat energy. Therefore, heating is taking place.
If Tfinal is less that Tinitial, it means the object has lost some heat energy and cooling is taking place.
Answer:
Negative
Explanation:
There are more electrons (negative charge) than there are protons (positive charge).
If you want to see something in fine detail, you should focus the light the cornea. The lens works together with the cornea to focus light correctly on retina.
When light hit on retina special cells called photo receptors turn the light into electrical signals. The lens are the clear part of eyes behind the iris that help to focus light and image on retina to see something clearly.Lens is the important part of eye when it comes to focusing light so that we can see perfect clear image.
The retina is the most sensitive part which can effect by more light because retina convert incoming light into electrical impulse.

Answer; (not correctly matched)
Apocrine gland; Thermoregulation;
Explanation;
Apocrine glands are found in the skin and the eyelids.
Most apocrine glands in the skin are in the armpits, the groin, and the area around the nipples of the breast.
They are scent glands, and their secretions usually have a odor. They empty into the hair follicle just before they open onto the skin surface.
