Answer:
C. Troposphere
Explanation:
It works a lot like sunscreen, blocking out harmful ultraviolet (UV) rays from the sun. ... Most ozone is found below a 30 mile (48 km) height. ... And considering without an atmosphere we'd all die, it's kind of important to ... From the Earth's surface through the bottom layer of atmosphere, called the troposphere, temperature .
The only household units of measurements used in the administration of medication are based on volume
Answer: Fluorescence microscopy
Explanation:
A protein is substance that is the essential constituent of living cells because it forms part of its structure. T<u>hey are also found in plasma membrane</u>, where they assist substances to cross the membrane. Proteins can be:
- <u>Integral</u>: permanently attached within the plasma membrane.
- <u>Transmembrane</u>: it spans the entirety of the cell membrane.
- <u>Peripheral</u>: are only temporarily associated to the membrane.
Some integral proteins can act as cellular receptors. Other proteins are responsible for cell adhesion (binding of a cell to another cell or to a surface). On the outside of the cell membranes, attached to other proteins, are the carbohydrate chains that act as labels identifying the type of cell.
<u>A heterokaryon is a multinucleate cell and in this experiment the scientists fuse a human cell and a mouse cell, each of them will have their own proteins.</u> At first, the human and mouse proteins where found in separated halves of this heterokaryon. But <u>after a while, those proteins where mixed and could no longer be identified</u>.
A fluorescent chemical called a fluorophore is able to be absorb light of specific wavelengths and then emit light of longer wavelengths. The proteins can be modified and marked with different colored fluorophores to detect them, even if they are mixed in the heterokaryon. <u>Then, they can be seen with a Fluorescence microscopy, to identify them through different colors</u>.
