Bioethics

Back 51

Concerned with the ethicalquestions that arise in the relationships among science and ethics.

Front 52

Bioethics Case Discussed in Class

Back 52

Her Dying Prayers

The Nixons do not believein ‘faith healing’. We believe in divine healing through Jesus Christ.

Daughter Shannon dyed dueto possible diabetes, because only believe in healing derived from prayer.

Other of their children haddied from unattended illnesses

3 Pats of Cell Theory

Back 56

1.) All known living things are made up of one or more cells.

2.) All living cells arise from pre-existing cells by division.

3.) The cell is the fundamental unit of structure and function in all living organisms.
