The molecule that carries the genetic code from the nucleus to the cytoplasm is: MCQ with Answer and Explanation

Explanation:
The proximal convoluted tubule (PCT) reabsorbs about 70-80% of electrolytes and water, and almost 100% of glucose, amino acids, and vitamins back into the blood via active transport and facilitated diffusion. The loop of Henle concentrates urine, the DCT reabsorbs sodium and water under hormonal control, and the collecting duct reabsorbs water (ADH-dependent). PCT cells have microvilli for increased surface area.

Explanation:
The Mesozoic era (about 250-65 million years ago) is called the 'Age of Reptiles' or 'Age of Dinosaurs' because reptiles, especially dinosaurs, dominated terrestrial ecosystems. It is divided into Triassic, Jurassic, and Cretaceous periods. The Cenozoic is the 'Age of Mammals', the Paleozoic saw the rise of fishes and amphibians, and the Proterozoic is earlier.

Explanation:
Glucose (C₆H₁₂O₆) is a simple sugar (monosaccharide), the primary fuel for cells. Sucrose (glucose+fructose), lactose (glucose+galactose), and maltose (glucose+glucose) are disaccharides. Fructose and galactose are also monosaccharides. Monosaccharides are the building blocks of complex carbohydrates.
