Answer: The advantages of spines in these unrelated organisms are as follows:

- for escape and defence

- for regulations of body temperature

- for conservation of water

Explanation:

The evolution of spines in Tenrecs, echidnas and hedgehogs represent STRUCTURAL ADAPTATION i.e when a part of the body of a living organism undergoes changes to become structurally adapted to its mode of life.

- The evolved spines in hedgehogs are for physical defence

- in tenrecs, they are for physical defense

Stolb23 [73]

Answer:

Aerobic metabolism of amino acid requires deamination

Explanation:

Living system can be defined as the internal systems of organisms and how materials circulate within organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc., which are typically used for carrying out various bodily functions such as respiration, digestion, metabolism, etc.

Metabolism can be defined as a set of chemical processes carried out by a living organism such as humans, plants and animals, in order to sustain life.

Aerobic (oxygen-using) metabolism can be defined as a biological process that typically involves the extraction of energy from any carbohydrate source such as amino acids, fatty acids, etc.

Basically, an aerobic metabolism of amino acid is a process that requires deamination.

Generally, proteins comprises of amino acids and it is responsible for maintaining the proper functioning of the body system.

Transamination can be defined as a biochemical process which typically involves the removal of amino groups from amino acids and transferring them to a ketoacid (amino acid without an amine group), so as to form new amino acids.

Basically, transamination is a reversible oxidation-reduction reaction that is responsible for the deamination of amino acids.

n cancer cells one allele of the tumor suppressor gene p53 is frequently mutated so that the protein is inactive, not produced,
artcher [175]

Answer:

If the cancer cell's DNA is sequenced than the anticipated results will be that the cytosines in or close to the promoter region will get methylated. It has been stated that in the cancer cells one allele of p53 is mutated and the other allele, however, of exhibiting an intact promoter, does not express the protein.  

Thus, it shows that the expression in the other allele gets suppressed by methylation rather than by mutation. Methylation generally takes place in CpG islands in or close to the promoter region and therefore inhibits transcription.
