Facilitated diffusion is usually significant to pass the ions across the hydrophobic layer of the plasma membrane. Transmembrane integral protein and careers proteins provide the channels that allow the ion to pass across the membrane. When an ion bind to their active site on the protein (note that the proteins are very selective), the protein changes conformation. It is this change in conformation opens up the channel that allows the ions to be passed across the membrane. When the ions are released inside of the cell, the protein resumes normal shape (and the channel also closes) and the active site becomes available again or another ion.
Answer:
A
Explanation:
It allows every human to have their own unique DNA
hope this helps : )
Well, I may not name ALL of the minerals, but I can give you the names of some minerals I've known about:
1. Quartz
2. Magnetite
3. Mica
4. Diamond
But just to let you know, there are many minerals out here on Earth. All you have to do is either remember some minerals you know of, or just do some research.
Answer:
Basidiocarp
Explanation:
This is a multicellular structure found in mushroom that are visible to the naked eye and are spore producing. They are the structures of which spore producing basidia are formed. They called called false ruffles. The basidiocarps serve as the structure on which the hymenium is produced. They are the fruiting bodies of mushroom.
Antibiotic used include kenamycin, ampicillin and tetracycline. This is useful to determine if and which bacteria took up the plasmid as they were supposed to during the process of recombination. Host bacteria are normally killed by these antibiotics. If the recombinant plasmids were taken up by the bacteria, plasmid may have contained a DNA gene for resisting the effects of one or more antibiotics. Host bacteria are placed in a growth medium containing an antibiotic to which they have a resistant gene in their recombinant plasmid DNA survivor. If they havent taken the plasmid they die.
