what is biology?
(word for word)
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations.
Describe the structure of an atom, including the subatomic particles and their charges.
An atom consists of a nucleus (protons and neutrons) and electrons orbiting. Protons have a positive charge, electrons are negatively charged, and neutrons carry no charge.
What is Isacc Newtons second law?
the acceleration of an object is directly proportional to the net external force applied, and it is indirectly proportional to its mass.
What is the name of the boundary between Earth's mantle and core, located approximately 2,900 kilometres (1,800 miles) beneath the Earth's surface?
the Gutenberg discontinuity
