The structure that carries urine from the kidney to the bladder is the: MCQ with Answer and Explanation

Explanation:
Chlorophyll a is the primary photosynthetic pigment found in all algae and is essential for the light reactions of photosynthesis. Different groups of algae also contain other accessory pigments like chlorophyll b, c, phycobilins (phycocyanin, phycoerythrin), and carotenoids (fucoxanthin), which give them their characteristic colors (green, red, brown) and help in capturing light energy.

Explanation:
Stomata are surrounded by two kidney-shaped guard cells in dicots (dumb-bell-shaped in grasses) that control pore opening/closing via turgor pressure changes. When guard cells absorb water and become turgid, the stomatal pore opens; when flaccid, it closes. This process is influenced by light, CO₂ concentration, and abscisic acid (ABA). Stomata are critical for gas exchange and transpiration.

Explanation:
The fovea contains tightly packed cones with photopsins (iodopsins) sensitive to red, green, blue. Rhodopsin is in rods for dim light.
