The first term - Unit Three
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.
