Consider the following statements about carbohydrates: 1. Glucose is a monosaccharide. 2. Sucrose is a disaccharide. 3. Cellulose is a storage polysaccharide in plants. Which of the above is/are correct? MCQ with Answer and Explanation

Explanation:
During telophase, the chromatids reach the poles, decondense, and the nuclear envelope reassembles around each set, forming two daughter nuclei. The spindle disappears. Prophase involves nuclear envelope breakdown, metaphase aligns chromosomes, and anaphase separates chromatids. Cytokinesis often overlaps with telophase, dividing the cytoplasm.

Explanation:
The renal corpuscle consists of the glomerulus (capillary tuft) and Bowman's capsule. This is where ultrafiltration of blood occurs. The filtrate then passes through the proximal tubule, loop of Henle, distal tubule, and collecting duct. The loop of Henle concentrates urine, the tubules reabsorb and secrete. The nephron is the complete functional unit.

Explanation:
Louis Pasteur, through his famous swan-neck flask experiment (1861), demonstrated that life does not arise spontaneously from non-living matter. Sterilized broth in flasks remained sterile unless exposed to airborne microorganisms. Fleming discovered penicillin, Koch established postulates for microbial disease, Jenner developed smallpox vaccine. Pasteur's work was foundational for microbiology.
