Identify the INCORRECT statement about cell division:
A. Crossing over occurs in mitosis.
B. Cytokinesis follows nuclear division.
C. Meiosis results in four haploid cells.
D. Mitosis produces two identical daughter cells.
Answer: Option A
Solution (By JKSSB Mock Tests)
Crossing over occurs during prophase I of meiosis, not in mitosis. Mitosis produces identical diploid cells, meiosis reduces chromosome number by half, and cytokinesis divides the cytoplasm.
Explanation:
Residual volume (RV) is the air left in the lungs (about 1.2 L) after a forceful expiration. This prevents lung collapse and ensures continuous gas exchange between breaths. Tidal volume is normal breath volume, vital capacity is the maximum exhaled after maximum inhalation, and inspiratory reserve volume is the extra air that can be inhaled beyond tidal volume.
