Answer:
The types of volcanoes that I am aware of are dormant, active, and extinct. Active volcanoes are volcanoes that have erupted in the past 10,000 years. Dormant volcanoes are active volcanoes that are supposed to erupt in the future. Extinct volcanoes are volcanoes that have not had an eruption in the last 10,000 years and is not expected to erupt.
The answer is D. It allows population to become genetically different
Phagocytes refer to the procedure by which some kind of living cells known as phagocytes engulfs or ingest other cells or particles. The phagocyte may be a free-living one-celled species, like an amoeba, or one of the body cells, like a white blood cell.
In higher species, phagocytosis is mainly a defensive mechanism against infection and invasion of the body by the antigens, that is, foreign particles.
Thus, phagocytosis is illustrated by most types of white blood cells ingesting bacteria, viruses, and other foreign substances.
d. The farther an electron is from the nucleus, the greater its energy.
Explanation:
The energy of an electron relates with the distance from the nucleus in that the farther an electron is from the nucleus, the greater its energy.
The nucleus of an atom is where the protons and neutrons are located.
Electrons orbits round the nucleus in certain permissible energy levels.
- According to quantum mechanics and the Bohr's model of the atom, the energy levels of orbital electron is quantized.
- The ground state is the state with the lowest energy and close to the nucleus.
- The outer most electrons are located in the highest energy levels
- Therefore, the farther an electrons is from the nucleus, the greater its energy

Answer:
Mitochondria and chloroplasts
Explanation:
Mitochondria and chloroplasts each have their own DNA due to at one point being prokaryotes that fused with other prokaryotes.
