Answer:
Pretty sure it's A because people can redo this test as many times as needed to verify the answer.
The nucleotide
bases are adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U).
The bases combine with sugar to make them adenosine, guanosine, cytidine, thymidine, and uridine
repectively.
The bases can
be arranged in many different combinations and the genes in their long chains
can have trillions of different combinations.
Answer:
the answer is selective permeability
Explanation:
A membrane that has selective permeability allows only substances meeting certain criteria to pass through it unaided. In the case of the cell membrane, only relatively small, nonpolar materials can move through the lipid bilayer (remember, the lipid tails of the membrane are nonpolar).
I think it's Adipose tissue (not sure)
The computer chips come from semi conductive minerals usually germanium, silicon, and finding those in nature is not always easy but, they are minerals they are properly manufactured, firstly they are melted down and then are pulled into a giant single crystal that is perfectly shaped to fit the needs of the computer chip manufacturer, then they are cleaned and cut within a few thousandths of a inch usually thinner than a piece of paper and smaller than a rice grain, then etched with UV resin, washes, and copper to make microscopic pathways for transistors and so forth, then after that they are put into they're cases and have the very small like thinner than a hair small gold electrical wires attached to each point of the chip.So from a outside perspective yes they are still minerals but refined and manufactured to fit a purpose entirely different than the material itself is.
