The 'Urey-Miller experiment' synthesized which organic molecules? MCQ with Answer and Explanation

Explanation:
Root pressure is the positive hydrostatic pressure developing in the xylem of roots due to active transport of ions into the vascular cylinder, drawing water osmotically. It can cause guttation in some plants. Transpiration pull is the main driving force for water ascent. Turgor pressure is the pressure of cell contents against the cell wall.

Explanation:
Smooth muscle is non-striated, spindle-shaped, involuntary muscle found in the walls of hollow organs like intestines, blood vessels, uterus, and bladder. It controls peristalsis, vasoconstriction, and other autonomic functions. Skeletal muscle is voluntary and striated, cardiac muscle is striated but involuntary.

Explanation:
Renin, released by juxtaglomerular cells of the kidney when blood pressure drops, cleaves angiotensinogen (from liver) to angiotensin I. ACE then converts angiotensin I to the active angiotensin II, a potent vasoconstrictor and stimulator of aldosterone. Pepsin and trypsin are digestive proteases.
