This document discusses several questions in science, including cell theory, why we are here, and what happens after death. It explains cell theory - that all living things are made of cells that come from pre-existing cells. It notes that science aims to explain why we are here through the theory of evolution and natural selection, though people have different philosophical views. It also discusses people's reported near-death experiences and how science cannot truly study what happens after death through controlled experiments.

Questions In Science?

2. Cell Theory
• All living organisms are composed of cells. They may be unicellular or multicellular. The cell is
the basic unit of life. Cells arise from pre-existing cells.
• This table goes through the history of cell theory
This is now and answered science question because we can use the
proses of mitosis and meiosis to show that cells come from pre-existing
cells
If you are unsure about the proses of mitosis
and meiosis here is a YouTube video that will
help you understand

3. Why Are We Here?
• One question that science is in the process of answering it. They are doing this by
using the theory of evolution and natural selection. Evolution is and excepted
theory but different types of people do not 100% agree with it.
• This is also a very philosophical question because we know who were are to be
alive and living but we will never really know the true meaning of why we are
here. Different people will have different opinions on this matter.
• But why do you think you are here?...

4. What Happens After Death
• Many people have said that they have had a near death experience or an out of body
experience. This is what one scientist had said about this experience. “She recounted
experiences she had while dead -- like interacting with deceased relatives. Even more
amazing is that Reynolds was able to describe aspects of the surgical procedure, down to the
bone saw that was used to remove part of her skull”.
• Even though you hear about people having these experiences science will never be able to
work out what truly happen. This is because they are not able to have a controlled
environment or able to keep a constant. It also will be a very bias experiment because only
few people will ever be able to have the experience and also be brought back to life.
• If they were able to kill people and bring them back to life to try and work this out there
would also be a lot of ethical problems with this. This would make impossible for scientist to
find this out.
