Match the experimental approach with the corresponding experimental strategy.
approach:
x = biochemistry
y = genetics
z = cell biology
strategy:
i = watch the process in a microscope. follow the dynamics of particular proteins in a living cell. does inhibiting the function of a specific protein in a living cell block the process you are interested in?
ii = purify the proteins involved and study their behavior in vitro. recapitulate the process in a test tube.
iii = isolate a mutant organism that is defective in the process.

The correct answer is X=ii, Y=iii, and Z=i.

Explanation:

Biochemistry is the study of all chemical process(metabolic process) occurs in living organisms. Proteins make enzymes that catalyze any chemical reaction so proteins are studied in detail in biochemistry by purifying protein. Then the interaction and behavior of these proteins are studied in-vitro.

Cell biology involves the study of the structure and function of whole-cell and processes involved in the functioning of the cell. So formation of particular protein or inhibition of any process can be studied in cell biology. Cell and its process can be seen under a specific microscope.

Genetics is related to genes present in organisms so the study of mutant organisms comes under genetics because mutation occurs in a gene. Therefore the right answer is X=ii, Y=iii, and Z=i.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
