Answer:
20 feet blood vessels and 1000 nerve endings
Explanation:
The skin is the largest organ of the body and is composed of three layers that are epidermis, dermis and the subcutaneous layer. The outer layer is the epidermis consisting of cells that are tightly packed in around in 20 layers. The middle thick layer is the dermis that consist of glands, nerves, blood vessels, and hair follicles that provide skin its functions. The inner layer is the subcutaneous that is composed of connective tissue and fat.
The square inch of skin consist of 20 feet blood vessels, 1000 nerve endings, 650 sweat glands and 100 oil glands. The blood vessels supplies blood to the tissues and the nerve endings upon stimulation sends signals to the brain and generate response depending on the kind of stimulus like heat, pressure, pain, or temperature.
Answer:
When water is added to a graduated cylinder, having a surface where the sides of the water look higher than the center means that the curved surface is a concave meniscus which has formed because of surface tension (Choice C).
Explanation:
A meniscus is simply the curvature that the surface of a liquid acquires when it is in a container, such as a graduated cylinder. It is concave when there is attraction between molecules -water and glass- or it can be convex when both surfaces are repelled.
<u>Water is a polar molecule</u>, with the capacity to adhere to the surfaces it comes into contact with. This characteristic causes it to form a concave meniscus, as the outermost molecules adhere to the glass surface, while the surface tension of the water attracts the molecules from the centre downwards, causing the concavity.
