3. What do you think is the need of nomenclature?
| a. Scientists can use this term in their seminars |
| b. To have a standard name for an organism instead of having many names in different languages |
| c. Nomenclature is something which is same for all organisms and people need not mention each organism with different names |
| d. Nomenclature looks fancier and more technical than regional names |
Answer: b
Explanation: There are different languages and so different regional names for an organism. Therefore, scientists came up with the idea of binomial nomenclature. Binomial nomenclature is introduced to standardize the name of a living organism.
4. A binomial nomenclature consists of _______ and_________
| a. Generic name and Phyla |
| b. Class and Phyla |
| c. Generic name and specific epithet |
| d. Phyla and Kingdom |
Answer: c
Explanation: Generic name and specific epithet are the two parts of a binomial nomenclature. A generic name specifies the genus of an organism and the specific epithet describes the species to which it belongs to.

7. The scientific name of lion is _________
| a. Panthera Leo |
| b. Panthera Tigress |
| c. Panthera Lion |
| d. Panthera leo |
Answer: d
Explanation: Biological names are Latinized and written in Italics. The generic epithet starts with capital letter while the second component specific epithet starts with small letter. Here the binomial nomenclature of Lion is Panthera leo but not Panthera Leo. Also, in Panthera Tigress the second component is written in capital letter which means that Panthera Tigress is not the answer. And in Panthera Lion the word Lion is not derived from Latin which reflects that Panthera Lion is also not the answer.
8. Which among the following statements are correct?
| a. All the biological names have their origin in Latin |
| b. The first word in a biological name represents the species and the next represents genus |

| d. Panthera Tigress is the binomial nomenclature of a tiger |
Answer: b
Explanation: Biological names need not have their origin in Latin but need to be Latinized or to be derived from Latin irrespective of the origin. Also in binomial nomenclature the generic epithet should start with a capital letter followed by the specific epithet starting with a small letter.
9. The word “Taxa” means ________
| a. Phyla |

30. Which among the following best describes the word “Growth” in living organisms?

| c. All living organisms grow throughout their life |
| d. Growth is a sufficient characteristic to determine whether an organism is living or non-living |
Answer: b
Explanation: Increase in mass due to internal division and increase in number of organisms are twin characteristics of growth. In non-living organisms increase in mass occurs due to accumulation whereas in living organisms it happens due to the proteins and carbohydrates that we intake. Living organisms except plants grow until certain period of their life and then stop growing. Growth is not a sufficient a characteristic to determine if an organism is living. Sometimes it’s possible that even mountains and sand dunes grow due to an accumulation of sand.
