The scientist who coined the term 'cell' was: MCQ with Answer and Explanation

Explanation:
Secondary structure refers to local folding patterns like α-helices and β-sheets. Primary is amino acid sequence; tertiary is 3D folding; disulfide bonds are tertiary/quaternary; denaturation disrupts non-covalent bonds, not peptide bonds.

Explanation:
Crystallization is a property of non-living substances where molecules arrange in a definite pattern, e.g., salt crystals. Living organisms exhibit growth, reproduction, metabolism, cellular organization, and consciousness. Metabolism is a defining feature of all living organisms, occurring even in unicellular forms. Reproduction, though absent in sterile organisms like mules, is generally a characteristic. Growth in living beings is internal and intrinsic, unlike extrinsic accumulation in non-living things. Hence, crystallization is not a characteristic of life.

Explanation:
Saccharomyces cerevisiae (baker's yeast) ferments sugars, producing CO₂ that leavens dough. Alcohol evaporates during baking.
