The Universe and the Solar System

The vast universe is filled with millions of stars that are not enough

to light this extensive universe. This is because there are billion kilometers of cold dark space among these stars.

Everything changes in the universe. On Earth, generations of

humans and living organisms change. The same goes for stars as they always change so that the universe is never constant.

All galaxies get away from each other very fast. The universe is

continuously in a state of expansion.

The first term - Unit Four

Introduction The reason behind creation is the continuity of species. This is

to keep the living organisms from extinction and ensure their interaction with environment.

This occurs through reproduction that basically takes place

through the continual divisions of cells. Cellular divison differs

among different living organisms. It includes two types of divisions: ď ? Mitosis that aims to increase the number of cells. ď ? Meiosis that aims to decrease the number of

chromosomes to half during the formation of gametes.

Reproduction is classified according to the species of living

organisms: simple living organisms are divided asexually to

produce offspring identical to parents, whereas other complex

living organisms reproduce sexually sexual reproducation are a source of genetic variation.
