12) In developing the cell theory, Virchow proposed the idea that cells come from pre-existing cells. This was contradictory to
the beliefs of most scientists at the time. Louis Pasteur provided proof of this when he performed an experiment with sterilized nutrient broth. The broth in straight neck flasks grew bacteria, but the flasks with curved necks did not grow bacteria. How are scientific theories formed? A) from the opinions of very educated people B) from one experiment of a famous scientist C) from evidence gained by many experiments of many scientists D) ignoring any experimental evidence that does not fit the theory
-DNA is the blueprint for proteins, which play many roles in the body. PROTEINS play many roles in the body and determine many traits. The section of DNA that codes for a specific trait is called a GENE. In fruit flies, straight wings are dominant and curly wings are recessive.
When the Cheetah starts running, it generates its energy initially by aerobic respiration, where glucose is oxidised in the presence of oxygen, resulting in generation of ATP
