Explanation

Explanation

 The bond between a fatty acid and glycerol is called an ester bond.

This bond forms when the hydroxyl group (-OH) of glycerol combines with the carboxyl group (-COOH) of the fatty acid, releasing a molecule of water (H2O) in a process called dehydration synthesis.

Explanation

Chloroform is classified as a possible human carcinogen, particularly linked to liver and kidney cancer with prolonged exposure.

It affects the liver by causing cellular damage.

It has been shown to induce tumors in animal studies.

Explanation

Explanation

Enzymes (e.g., ribosomes, polymerases) catalyze the assembly of proteins from amino acids during translation.

While enzymes assist in building various biomolecules, their most direct and universal role is in protein synthesis.

Explanation

Cyanobacteria utilize phycobilins, specifically phycocyanin (blue) and phycoerythrin (red), as accessory pigments in addition to chlorophyll a.

These pigments help cyanobacteria absorb light across a wider range of wavelengths than chlorophyll a alone, enhancing their photosynthetic efficiency.

Explanation

The iodoform test is a chemical reaction used to identify the presence of a methyl ketone group (CH3-CO-) in a compound.

When a methyl ketone reacts with iodine and sodium hydroxide, it produces a yellow precipitate of iodoform.

This makes the iodoform test a reliable way to detect methyl ketones.
