Orbitals are space around the nucleus where electrons orbit. Several orbitals can exist in a given energy level/shell. Carbon is the sixth element of the periodic table with 6 electrons. Carbon atoms have the ability to bond to themselves and to other atoms with sp, sp² and sp³, hybrid orbitals. Several orbitals in carbon are spherical conformation and this accounts to about 40% of the orbitals.
Answer:
Chemotherapy drugs and other toxins are actively pumped out of cancer cells by transmembrane proteins.
Explanation:
Drugs inside the cell can be inactivated by oxidation and / or conjugation with glutathione, such as glutathione S-transferases, playing an important role in detoxification. However, conjugation is not enough for drug elimination. And this is where the GS-X pumps appear. Transporter proteins, such as Mrp protein, act as GS-X pumps. The PgP, Mrp and Bcrp proteins function as expulsion pumps, thus reducing the intracellular accumulation of drugs, causing resistance in cancer cells.
Answer:
The answer should be B. G-T-A-G-C-T
A pairs with T and G pairs with C.
The wall would absorb extra heat during the day when the sun is out, then release the heat back into the room when the sun goes down.
Explanation:
Divide 67.6% by 201 of mercury
Divide 10.8% by 32 of sulfur
Divide 21.6% by 16 of oxygen
Then divide number by itself .
Example : Divide 2.97 by both sulfer moles and oxygen moles . Multiply by 2 to get whole number
