Answer:
Protons and neutrons are heavy, Electrons are extremely light
Explanation:
Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom. Electrons are extremely lightweight and exist in a cloud orbiting the nucleus.
Answer:
D.
Explanation: Both have shapes determined by gravitational forces.
If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.
The process is mitosis.
It is a kind of cell division where all the daughter cells are genetically identical to its parents cell, same with 2 sets of chromosomes.
The process must be mitosis because all cells in your body (except for gametes) has the same amount of chromosomes, which is 46 for humans.
Mitosis also ensure that you are still yourself when you're growing up, not having for example blue eyes in 5 and brown in 10 years old. All the alleles are identical.
