Living organisms can be characterised but not defined by:
I. | Reproduction |
II. | Growth |
III. | Cellular organisation with metabolism |
IV. | Consciousness |
1. Only I and II
2. Only III and IV
3. Only I and III
4. Only II and IV
Emergent properties at a higher level of organisation:
I: | are not present in the individual constituent units. |
II: | arise as a result of interactions among the constituent units. |
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
1. | The first word in a biological name represents the specific epithet and the second is a genus name. |
2. | The names are derived from Greek and written in italics. |
3. | When written by hand, the names are to be separately underlined. |
4. | Biological names can be written in any language. |
1. | Cyprinidae | 2. | Hominidae |
3. | Calliphoridae | 4. | Muscidae |
1. | X - Generic name, Y - Specific epithet, Z - Carolus Linnaeus |
2. | X - Specific epithet, Y - Generic name, Z - R.H. Whittaker |
3. | X - Specific epithet, Y - Generic name, Z - Carolus Linnaeus |
4. | X - Generic name, Y - Specific epithet, Z - R.H. Whittaker |
Assertion (A): | Reproduction cannot be an all inclusive defining characteristic of all living organisms |
Reason (R): | There are many organisms which do not reproduce such as mules, sterile worker bees and infertile human couples |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
Assertion (A): | An isolated metabolic reactions outside the body of an organism, performed in a test tube is neither living nor non-living |
Reason (R): | Isolated metabolic reactions in vitro are non-living reactions |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
Assertion (A): | There is a need to standardise the naming of living organisms such that a particular organisms such that a particular organism is known by the same name all over the world |
Reason (R): | Local names vary from place to place which create confusion |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
