Answer:
d. Lysine is replaced by tryptophan (nonpolar)
Explanation:
Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.
If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.
Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.
Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.
The plant tissue that is responsible for transport of the blue water to the flower is the XYLEM VESSELS.
Xylem vessels are responsible for upward transport of water and minerals from the roots to the stems and to the leaves.
The answer is C.
Non-renewable resources are resources such as, coal, natural gas and oil, which is usually harmful to the environment and causes pollution. Renewable resources are resources are energy sources such as solar energy, wind, ocean currents etc., these energy sources have a positive effect on the environment.
Hope this helps :)
That can be true. Everyone (mother) is different. That usually goes away after nursing for awhile.
Animal need Oxygen while Plant need Carbon Dioxide
