Consider the following two statements:
I. In the single-celled organisms, we are not very clear about the usage of the two terms – growth and reproduction.
II. When it comes to unicellular organisms like bacteria, unicellular algae or amoeba, reproduction is synonymous with growth, i.e., increase in number of cells.
1. Both I and II are true and II explains I
2. Both I and II are true but II does not explain I
3. I is true but II is false
4. Both I and II are false
Consider the following two statements:
I. Cellular organization of the body is the defining feature of life forms.
II. Metabolic reactions cannot be demonstrated outside the body in cell-free systems.
1. Both I and II are true and II explains I
2. Both I and II are true but II does not explain I
3. I is true but II is false
4. Both I and II are false
The most obvious & complicated feature of all living organisms is:
(1) The ability to sense their surroundings or environment and respond to these environmental stimuli.
(2) Reproduction - sexual or asexual - for production of progeny of own kind.
(3) The ability to growth in size due to cell division.
(4) Presence of complex organs systems such as digestive and nervous system.
Identify the incorrect statement:
1. | Biological names are generally in Latin and written in italics. They are Latinised or derived from Latin irrespective of their origin. |
2. | The first word in a biological name represents the genus while the second component denotes the specific epithet. |
3. | Both the words in a biological name, when handwritten, are separately underlined, or printed in italics to indicate their vernacular origin. |
4. | The first word denoting the genus starts with a capital letter while the specific epithet starts with a small letter. |
The scientific term for biological classification categories is the:
(1) Species

How many of the following statement (s) are correct?
(1) Each genus may have one or more than one specific epithets representing different organisms.
(2) Species is a group of individuals with highest fundamental similarities and maximum number of organisms
(3) Genus comprises a group of related species which has more characters in common in comparison to species
(4) leo and pardus are two different species but both belong to the genus Felis
