NEET Practice Questions (MCQs) with Answers & Solutions

The summary states: 'Based on the resemblances and distinct differences, each organism is identified and assigned a correct scientific/biological name comprising two words as per the binomial system of nomenclature.'

The summary states: 'The branch of knowledge dealing with these aspects [identification, nomenclature and classification of organisms] is referred to as taxonomy.'

Based on the rule, 'The first word in a biological name represents the genus while the second component denotes the specific epithet,' 'sapiens' is the specific epithet for Homo sapiens.

According to the NCERT text, 'A simple microscope has a limited maximum magnification (≤ 9) for realistic focal lengths.'

The NCERT states: 'The lens nearest the object, called the objective, forms a real, inverted, magnified image of the object.'

The NCERT states: 'This serves as the object for the second lens, the eyepiece, which functions essentially like a simple microscope or magnifier, produces the final image, which is enlarged and virtual.'

The NCERT states: 'Clearly, the final image is inverted with respect to the original object.'

The NCERT defines it as: 'The distance L, i.e., the distance between the second focal point of the objective and the first focal point of the eyepiece (focal length $f_e$) is called the tube length of the compound microscope.'

According to the NCERT (Eq. 9.43): 'The (linear) magnification due to the objective, namely $h'/h$, equals $L/f_o$.'

The NCERT states: 'Clearly, to achieve a large magnification of a small object (hence the name microscope), the objective and eyepiece should have small focal lengths.'
