1. What is science? 2. Name the three branches of science. 3. What is the universe? 4. What is nature? 5. Define biology, chemistry, and physics? Explain how they are related to science?

1-Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE.

2-The three branches of Science include Physical Science, Earth Science, and Life Science. Each of theses branches include a number of sub-branches. Physical Science includes areas such as Chemistry and Physics. Earth Science includes areas such as Geology, Meteorology, and Astronomy.

3-The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe

4-the phenomena of the physical world collectively, including plants, animals, the landscape, and other features and products of the earth, as opposed to humans or human creations.

5-biology is the study of life, more specifically "a branch of knowledge that deals with living organisms and vital processes"; chemistry consists of "a science that deals with the composition, structure and properties of substances and with the transformations that they undergo Physics is the basic physical science. ... Physics can, at base, be defined as the science of matter, motion, and energy. Its laws are typically expressed with economy and precision in the language of mathematics.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
