The correct options are:
- Matter is made of small particles.
- Matter's particles are in constant random motion or vibration
- There is empty space between matter's particles.
Anything which has mass and occupies shape is a matter. Matter is composed of particles. The particles of matter are very small in size and they attract each other. There is space between the particles. The particles are in continuous random motion, thus they have kinetic energy. on absorbing energy their movement increases.

Answer:
The best way to determine if these populations form part of the same species is to study the existence of reproductive isolation between populations. Moreover, the result of an experiment based on the study of reproductive barriers may be complemented with molecular biology approaches that determine the level of sequence homology between populations
