The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body.
<h3>
The lining of the air sacs in the lungs (alveoli) is comprised of what epithelium?</h3>
Simple squamous epithelium contain the air sacs or alveoli of the lungs. This kind of squamous epithelial cells are slightly porous which allows the oxygen from the air to enter the blood in the capillaries of the lung. So the squamous epithelium is the epithelium in which the lining of the air sacs or alveoli occurs. Each alveolus is lined by the squamous epithelium.
So we can conclude that: The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body.

Answer:
Receptors are highly specific and only have high affinity for those ligands for whom they are specific.
Explanation:
Receptors are proteins that receive a stimulus or bind a ligand and mediate effects via receptor effector system.
Receptors are macromolecules that are highly specific.
The affinity between the ligand and the receptors is determind by the disassociation constant Kd.
The receptors produce maximun effect when an appropriate specific stimulus is present.
Different recptors types are present for different ligands.
For example, muscrinic receptors are specific for acetycholine and adrenergic receptors are specific for adrenaline/nor adrenaline.
It is important to know the specificity so that the body remains in a state of balance.
Answer:
They help our ecosystems and food chains all over the world
Explanation:
Autotrophs are the most important organisms on the planet because they are fundamental to food chains all over the world. They take energy from the environment in the form of sunlight or inorganic chemicals and use it to create fuel molecules like carbohydrates to release the hydrogen atoms that fuel the metabolic process of primary production.
