Frameshift mutations such as the substitution or deletion of a base can alter the entire DNA base sequence after the point where the base was substituted/deleted, this it causes the triplets to code for different amino acids which in turn results in the sequence of amino acids changing.
As the primary structure (amino acid sequence) changes, this causes the secondary and hence tertiary structure to change as well, causing the protein to become dysfunctional.
In comparison to point mutations which include silent, inversion, etc mutations, these mutations may cause only a single amino acid to either stay the same or change as a tiny region of the DNA base sequence is altered slightly, unlike frameshift mutations which may cause a huge portion of the DNA base sequence to be altered.
Answer:1)Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance
2)Cell membranes in reindeer legs (near the hooves) are kept flexible because they have a large number of saturated fatty acids.
3.)Cell membranes in cold tolerant winter wheat plants have a higher ratio of unsaturated fatty acids to saturated fatty acids than do cold intolerant wheat varieties.
Explanation.
Basically the longer the chains of fatty acids the higher the degree of energy produced as heat energy, and therefore the higher the insulation.
Unsaturated fats clogged together and the aggregate carbons and hydrogens ensured insulation.
The homology of animals is based on scientists current understanding on the evolutionary history of living species.
A hypotonic solution is one where the solute concentration is greater in the solution relative to other systems. That means the water concentration is lower in the solution relative to other systems.
