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.

Explanation:
I typed into calculator hope it's right.
The answer is electron.
The nucleus of a neutral potassium atom is "surrounded" by electron.
The neutral potassium atom contains equal number of protons and neutrons, and there are 19 electrons and 19 protons while 20 neutrons.
20 protons and 20 neutrons are there in the nucleus while 19 electrons surrounds the nucleus in different orbits .
With the advancement of science, electrons seemed to possess both particle and wave nature.
this is called the dual nature where electrons have both particle and wave properties.
earlier it was believed that electrons used to orbit around the nucleus in orbits.
Later it was found that electrons do not have fixed positions, the exact momentum and position of electrons cannot be determined at the same time
therefore the wave mechanical model was introduced which introduced orbitals.
Orbitals are spaces in which electrons are most likely to be found. These regions have the highest probability of an electron being found here.
correct answer is 3) an electron
Atomic number, atomic mass, symbol of element
