Answer:
Adding NaCl to a saturated PbCl2 solution will decrease the Pb2+ concentration.
Explanation:
If a solution is saturated this means it cannot dissolve more material.
PbCl2 ⇆ Pb2+ + 2Cl-
Adding more Cl- in the solution is the same thing as trying to dissolve more of the material. In the solution, the concentration of Cl- will increase.
In order for the Ksp to maintain a constant value, the concentration of Pb2+ must decrease if the concentration of Cl- is increased.
Adding NaCl to a saturated PbCl2 solution will decrease the Pb2+ concentration.

Answer:
(D.)
The core of the pyruvate dehydrogenase complex is made up of eight catalytic <u>trimers </u>that make up the<u> E2</u> component.
Explanation:
Eight trimers assemble as a hollow truncated cube, which forms the core of the multi-enzyme complex, known as the E2 complex in human pyruvate dehydrogenase complex.
Hypotheisis is just like an initial building block for a building. The true statements about hypothesis among the given are-
- First guess- hypothesis is a proposed explanation for something which is observed. Thus the explanation is just a guess and not a proved one.
- An initial idea which is assumed to be true - The whole experiment or research is based on an assumption which is supposed to be true and the scientist works to prove that true.
