The scientist who discovered the phenomenon of transformation in bacteria was: MCQ with Answer and Explanation

Explanation:
Glycolysis, occurring in the cytoplasm, breaks down one molecule of glucose (6C) into two molecules of pyruvate (3C), producing a net gain of 2 ATP and 2 NADH. This is the first step of both aerobic and anaerobic respiration. Pyruvate then enters the mitochondria for further oxidation in the Krebs cycle if oxygen is available.

Explanation:
The vertebral column (spine) consists of vertebrae stacked to form a canal that encloses and protects the spinal cord. The skull protects the brain, rib cage the thoracic organs, pelvis the pelvic organs.

Explanation:
The pineal gland is a small, pinecone-shaped gland located in the epithalamus, near the center of the brain. In humans, it is not a true eye, but it is photosensitive; it receives information about the light-dark cycle from the retina via the suprachiasmatic nucleus and the sympathetic nervous system, and uses this to regulate the secretion of melatonin, thus controlling circadian rhythms. In some lower vertebrates (like certain reptiles, amphibians, and fish), the pineal complex includes a parietal eye (or 'third eye'), a light-sensitive organ on the top of the head that can literally detect light and shadows, helping with camouflage and predator detection.
