Answer : The chain of many building blocks can be called as polymers in general.
Explanation : Polymers are large units of molecules in structure which are combined by the smaller repeating units called as monomers. Every macromolecule can be defined differently, like proteins are polymers made up of amino acids. Cellulose is a polymer made up of glucose monomers. The building blocks of nucleic acids are called as nucleotides.
F (Fluorine) has the highest electronegativity with a value of 4.0
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.
First convert grams to moles:
90.0g *(mole/39.997) = 2.250mole
Remember that molarity is moles per liters:
2.250mol/3L = .750 M
