D. Effusion
E. Isoelectric point

Answer 1

Hint: In order to solve the question you must remember the definition of the pH value of the solution in which a particular amino acid does not migrate under the influence of an electric field is called the isoelectric point.

Complete Step by Step Solution:
Eutectic point: A homogeneous, solid mixture of two or more substances called an eutectic system forms a super-lattice that melts or solidifies at a temperature lower than the melting point of any of the constituent parts. The phrase is most frequently used to refer to a metal mixture. A eutectic system only develops when the component ratios are precisely balanced. The Greek words "eu," which means "good" or "well," and "tecsis," which means "melting," are combined to get the English word "eutectic."

Yielding point: In structural engineering, the yield point refers to the stress at which a solid material that has been stretched starts to flow or irreversibly change shape. It is the point on a stress-strain curve that denotes the end of the behaviour of stretch ability and the start of the behaviour of plasticity. Lower than the yield point, a material will stretch ability to deform, and it will revert to its previous shape once the yield stress point is removed.

Neutralisation point: When both the acid and the base in the reaction have been fully used and neither is in excess, the reaction has reached its equivalence point or neutralisation point.

Effusion: Effusion is said to happen when gas molecules escape into a vacuum through a pinhole. The capacity of gas to pass through a small aperture is known as effusion. When a hole's size or aperture is less than the molecules' mean free path, effusion takes place. A difference in pressure causes or facilitates effusion.

Isoelectric point: The pH value of the solution in which a particular amino acid does not migrate under the influence of an electric field is called the Isoelectric point

Note: The thing to note here is the respective definitions of different terms.
