Explanation:
Bt cotton is genetically modified by inserting the cry gene from Bacillus thuringiensis, which produces an insecticidal protein toxic to bollworms. Triticale is a hybrid of wheat and rye (not GM per se), Brassica napus is rapeseed (canola) which may have GM varieties, but Bt cotton is a classic example.

Explanation:
Veins have thinner walls than arteries and contain valves. The pulmonary artery carries deoxygenated blood, and arteries normally (except pulmonary) carry oxygenated blood.

Explanation:
The Smooth Endoplasmic Reticulum (SER) in liver hepatocytes contains enzymes like cytochrome P450 that detoxify lipid-soluble drugs, metabolic waste, and toxins by making them water-soluble for excretion. Rough ER is involved in protein synthesis, the Golgi apparatus in packaging and secretion, and lysosomes in intracellular digestion. Exam tip: SER is abundant in liver and adrenal cortex cells.
