Answer: Linoleic acid is an unsaturated fatty acid.
Explanation: Fatty acids are carboxylic acids with long long chains of hydrcarbons whose hydrocarbon chains can be straight (linear) or branched, saturated or unsaturated.
Saturated fatty acids are those fatty acids in which all the carbon-carbon bonds are single bonds while unsaturated fatty acids in which there is presence of one or more double bonds. When a fatty acid contains only one carbon-carbon double bond, it is said to be monounsaturated but when it contains more than one carbon-carbon double bond, it is said to be polyunsaturated.
From the diagram above, Linoleic acid has two carbon-carbon double bonds, there it is unsaturated.
The molecular technique is used to distinguish and evaluate the similarities and differences of the genomes of the various organisms of the same species. This method was first discovered by Charles Darwin when he did research in the Galapagos Islands. He was able to see the similarities and the difference between species depending on how they adapt to their physical environment.
Answer:
ringworms are fungis
they transmit viruses and bacteria to humans
The least useful technique in the study is C. Comparisons of items eaten for food. This is the least scientific method of studying two different species because many animals can want the same food and not have any relation with each other. It isn't considered an important factor in determining the similar characteristics of species, especially in terms of genetic makeup.
