characters?

3. What is DNA barcoding?
4. What is evolution?
5. Enlist uses of taxonomy.
Answers
Answer:
tendency to variation during reproduction, both because of errors in DNA copying, and as a result of sexual reproduction, evolution takes place
Answer:
1. The characters of organisms that can be seen or observed with "naked eyes" are called "visible characters".
2. The recent approaches in taxonomy involve study of fossils and other paleontological sources to build up the evolutionary taxonomy.
3. DNA barcoding is the process of identifying a DNA using a smaller section of DNA from the specific genes that is to be identified.
4. Evolution is the process by which all kinds of living organisms have developed from their earlier forms by undergoing certain changes, so as to maintain its survival on this planet.
5. Taxonomy is used to understand and organize the diverse floral and faunal components of this planet.
Explanation:
1. The characters of organisms that can be seen or observed with naked eyes are called visible characters. For example, Presence of external Pinna in mammals, which can be observed by naked eyes, is a visible character of mammals.
2. The recent approaches in taxonomy involve study of fossils and other paleontological sources to build up the evolutionary taxonomy. This technique also helps to provide and prepare records about the genetic information of the organisms.
3. DNA barcoding is the process of identifying a DNA using a smaller section of DNA from the specific genes that is to be identified. DNA barcoding is widely used to identify various strains to animals, plants, fungi and thus make various products from them.
4. Evolution is the process by which all kinds of living organisms have developed from their earlier forms by undergoing certain changes, so as to maintain its survival on this planet. The concept of evolution was first put forward by Lamarck but in a very preliminary form, the concept of evolution was mostly popularised by Charles Darwin.
5. Taxonomy is used to understand and organize the diverse floral and faunal components of this planet. Taxonomy is referred as organizing animals and plants into groups based on their similarities and differences.
