Answer:
True
Explanation:
Point mutations arise when a single amino acid base is changed. This could cause some differences in the organism or it may not. Manufactured point mutations in model systems such as yeast offer a powerful tool to examine the function of different amino acids in a protein.
There are three types of point mutations
- Silent: these mutations have a single residue change but it does not affect the amino acid that is being coded. There is no change to the wild type
- Nonsense: will cause a stop or start or gain of start/stop codon.
- Mis-sense: will cause a change of amino acid residue. There are two types of mis-sense Conservative and non-conservative. The former will cause a change in amino acid base to one that has similar properties while the former will change to an amino acid of different properties often having different traits than the wild type.

Answer:
True
Explanation:
<em>The latter studies truly showed that some factors other than genetic predisposition play a role in obesity.</em>
The composition of the genome of an individual might predispose such individual to a higher risk of being obese. However, that such individual will become obese depends on some other factors, the most important being the kind of lifestyle the individual lives.
A lifestyle such as eating foods high in fat content, not eating adequate fruits, not eating eating adequate vegetables and drinking a lot of alcohol can cause someone to be obese apart from genetic predisposition.
Spontaneous generation is the belief that there is a form of creation of a living organism that just happens or can occur from an inanimate or dead object. Although disproved, some people still debate it today. The importance of it in relation to the scientific community and cell theory is one that provides guidance for adhering to the most rigid of standards in order to be actually considered scientific and that observation alone is not credible. It could be related to cell theory by suggesting the conversion of one type of cells to another spontaneously, which would be impossible as we now know without the intervention of another living organism like bacteria. The cellular level of these living organisms being incredibly small.
