The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
From inward to outward, the layers are: the core, the radiative zone, and the convection zone.

Answer:
D. Diseases are caused by the presence and action of specific microorganisms.
Explanation:
Answer:
a. Exothermic.
Explanation:
We know that there are several types of chemical reactions. In some reactions, the energy which is absorbed to break down the bonds of the reactants becomes less than the energy which is released at the time of forming new bonds of the products.
This means that in the whole reaction, energy is released as either light or light. This type of reaction is called an exothermic reaction.
Most fat-soluble nutrients are absorbed in the Lymphatic system.
<h3>What is Lymphatic System?</h3>
A network of tissues, veins, and organs known as the lymphatic system collaborates to transport lymph, a colorless, watery fluid, back into your circulatory system (your bloodstream).
Your body's arteries, smaller arteriole blood vessels, and capillaries each day carry about 20 liters of plasma. About 17 liters are then returned to the circulation through veins after providing nourishment to the body's cells and tissues and collecting their waste products. The remaining three liters permeate your body's tissues via capillaries. The lymphatic system gathers this extra fluid, which is now known as lymph, from your body's tissues and transports it to various locations before returning it to your bloodstream.

If the inner lining of the air sacs neither thin nor highly vascularized, then it can be inferred that AIR SACS ARE CANNOT BE THE SITES OF GASEOUS EXCHANGE BETWEEN AIR AND BLOOD. Air sacs are generally lined with mucus and surrounded with blood capillaries.
In case of birds, air sacs play an important role in respiratory system.
