C6H5O6 mainly. It is a protein that is chemically quite similar to honey, and there have actually been several experiments attempting to turn sweat into honey. It is possible, but it is too expensive to be worth it.
The sweat glands make sweat, also known as perspiration.
Yes, sweat glands are made of modified epithelial tissue. They are formed by invaginations of the epidermis (outer layer of the skin) and consist of coiled tubular structures. These tubular structures are lined with specialized sweat gland epithelial cells that secrete sweat.
hypothalamus and pituitary gland
The main part of the sweat gland is situated in the dermis layer of the skin, however the tubes reach the epidermis/outer layers of the skin. Sweat glands are found all over human body (around2-5 mill), but are most abdundant in palms, feet and forehead. There are two types of sweat glands: eccrine and apocrine glands and are made up of epithelium tissue, surrounded by a network of capillaries
A mixture is when more than one item or ingredient is blended together. A popular example is a Gin and Tonic - two liquids that blend perfectly to form a pleasant mixture.
Sweat is water. But it is not all water. It contains urea and sometimes lactates. It also has minerals that may include sodium, potassium, calcium, magnesium and smaller amounts of zinc, copper, chromium, nickel and lead. However, it also depends on how much of these you have in your body. If you have a high amount of these things in your body, more will escape in the sweat.
Air is not. It is often confused as being Oxygen, which is an element. The air we breath is made up of Oxygen and Nitrogen. So, it is made up of elements.
Oobleck is a heterogeneous mixture more commonly known as a suspension. The mixture is made up of cornstarch and water. It will behave as either a solid or liquid depending on pressure.
A solid and a liquid. A suspension is a mixture usually of a fine powder with a liquid that the solid will not dissolve in. The solid is mixed thoroughly into the liquid and "levitates" in the liquid. The solid can usually be removed from the liquid by spinning in a centrifuge or filtration.
No. Air is a mixture of Nitogen, Oxygen and Carbon Dioxide. Each of these elements can be condensed seperately to a liquid form at different temperatures and pressures.
A solution is a solid (the solvent) dissolved in a liquid (the solute). A heterogeneous mixture is two substances in different states (i.e. a gas and a liquid) that are in the same space and are in contact with each other. When you have a solution that is a gas-gas or a liquid-liquid or possibly a solid-solid solution, the matter of greater amount is the solute. A solution is an example of a homogeneous mixture (can't see the particles with a naked eye). But with heterogeneous mixtures, you can see the particles.
The oceans are made primarily of liquid water. The atmosphere is made primarily of a mixture of gaseous Oxygen (20%) and Nitrogen (80%).
