Answer:
Four major cell types produce a physical and chemical barrier to infection of the airways, including ciliated cells, mucus-secreting goblet cells, and club cells, which produce antimicrobial compounds and basal cells which, along with club cells, serve as regional progenitor cells to replenish the other cell types
Hi! Is this your first question?
Welcome!
Anyways,
Stains are made of different types of molecules, a range of enzymes are needed to break them down. ... Proteases break down proteins, so are good for blood, egg, gravy, and other protein stains. Amylases break down starches, and lipases break down fats and grease.Nov 15, 2007
Answer:
As you move from red to violet, the wavelength decreases and energy increases.
Explanation:
Here are the 7 from shortest to longest wavelength. Violet - shortest wavelength, around 400-420 nanometers with highest frequency.
hope it helps :)
Answer:
Cations are ions that are positively charged. They form when they lose an electron because they would have more protons than electrons. In your problem you have for example potassium (number three).
Iodine is a cation because it lost one electron. The ion symbol then would be:
I ⁺
So this is your clue. If it has a positive or a plus sign on top, that would make it a cation. Another clue would be if it LOST an electron, then it is a cation.
An anion, on the other hand, is negatively charged, because they gain electrons, making the electrons more than the protons. In your problem, you have Iodine as an example (number one).
Iodine gained one electron and the ion symbol would be:
I⁻
So again that is your clue for anions, they have a negative or a minus sign on top of the symbol. If they GAINED an electron, that would make them an anion.
Naming monoatomic anions is easy. They are named with the suffix -ide at the end. (Cations retain their name). For example Sulfur (number two).
Sulfur is an anion that gained two electrons with an ion symbol of:
S²⁻
So from the name <u>Sulfur</u><u> </u>the name will change into "Sulfide" and its name will now be <u>Sulfide ion. </u>
Correct! molecules going through reactions always want to form products that are less in energy so that molecules can be more stable. ATP molecule when made is not very stable and so it is high in energy. So when hydrolyzed, it breaks down to something simple and releases energy and achieves a less free energy (deltaG) state
