The nervous system in a frog controls the activities of the organs of the body. It also would regulate the internal environment in one's body. All the organs which are also the same parts of nervous system of a vertebrate are present in a frog. The brain,spinal chord,the sympathetic and para sympathetic nerves,cranial nerves,spinal nerves,cranial nuclei and ganglia.
Answer:
Asparagine because it is an amino acid structurally similar to the Glutamine and both have the same charge (polar neutral).
Explanation:
Glutamine (Gln or Q) is an amino acid similar to the glutamic acid, with the exception that the carboxylic acid group is replaced by an amide. In addition, glutamine, serine, threonine and asparagine are polar neutral amino acids.
Asparagine and glutamine have a similar chemical structure due to both amino acids contain amide groups in the side chain (both are dicarboxylic amides), thereby a substitution involving these amino acids will have few deleterious effects on the resulting protein.
A conservative substitution is a replacement where the modification is produced by substituting amino acids with similar biochemical properties (in this case, polar neutral).
Answer:
(Not wanting to spend or use something)
Explanation:
Like someone or something really cheap, not wanting to use something in a way that it is a waste.
A man's car broke down, he didn't want to spend any money repairing it so he did it himself.
Or could just mean being careful with your resources.
