Question

substance containing two or more components that are blended uniformly so that individual components are indistinguishable with a microscope
homogeneous mixture
compound
physical property
heterogeneous mixture
element or compound that cannot be broken down into simpler components without losing the properties of the original substance
substance
suspension
distillation
solution
any characteristic of a material, such as size or shape, that can be observed without changing the identity of a material
chemical property

Explanation:

First Question

A homogeneous mixture has components blended uniformly, and individual components are indistinguishable (even with a microscope). A compound is a pure substance with fixed composition, a physical property is a characteristic without changing substance, and a heterogeneous mixture has distinguishable components. So the correct option is Homogeneous Mixture.

A substance (element or compound) can't be broken down into simpler components without losing its properties. Suspension is a heterogeneous mixture, distillation is a separation method, and solution is a homogeneous mixture. So the correct option is Substance.

A physical property is a characteristic (like size, shape) observed without changing the material's identity. Chemical property involves chemical change. So if "Physical Property" is an option, that's correct.

Answer:

A. Homogeneous Mixture
