Almost done somebody please help me

The correct answer is A. It is uniform in composition and the parts that make up the mixture can be separated from one another through physical means.

Explanation:

In a homogeneous mixture, components are completely integrated, which means the final substance is uniform and the parts that compose it are not separated. This occurs in milk because this integrates uniformly water, fat, among others, and these elements cannot be observed separately.

Moreover, in mixtures, components can be separated through physical means; for example by heating the substances. This applies to milk because if it is heated water evaporates, and therefore can be separated.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
