Answer:
to preserve its stability.
to avoid cross contamination.
Explanation:
Biological evidence refers to all biological materials such as hair, tissue, bones, teeth, blood or other bodily fluids etc. These biological materials are collected from the site of crime. These evidences helps in finding the criminals. These biological evidences has to be kept at safe place in order to avoid contamination and preserve its stability so it can be used for solving the problem.
After development of Robert Hooke's light microscope, early elements of the cell theory were proposed. The invention of light microscope made it easy to study the structure of microscopic cell. After deciphering the cell structure with the help of a light microscope the cell theory was proposed. The invention of microscope was a big break through in the scientific world as it enabled researchers to study the microscopic structure. Later, the microscopes were modified to study the cellular organelles and prokaryotic microorganisms.
Cell theory provides the foundation for the study related to cells such as molecular biology, cell biology, etc.
Answer:
Both chances are 2 out of 4 (assuming you use a 2x2 punnet square), or 50%
The answer is:
E. 30,000
Since a replicon is known as the amount of DNA which is replicated from a single ori. Since bacteria only have one ori, they only have one replicon. The human genome has approximately 30,000 ori, so there will also be 30,000 replicons in a human focus.
Answer:
The metabolism that most likely occured was a mixed acid fermentation.
Explanation:
The metabolism of E. Coli is heterotroph, facultative anaerboic. This means that the organism can generate energy by using oxygen but also by mixed acid fermentation. As the analysis of the broth showed the presence of formic, acetic and lactic acids and increased levels of carbon dioxide - all products of the mixed acid fermentation - we can suppose that the mixed acid fermentation occured.
