The branch of biology dealing with the study of algae is called: MCQ with Answer and Explanation

Explanation:
Electron microscopes use beams of electrons to achieve much higher resolution than light microscopes, enabling visualization of organelles and macromolecular complexes. Types include TEM (internal) and SEM (surface). Light microscopes use visible light, spectrophotometry measures absorbance, chromatography separates.

Explanation:
The standard hierarchy (descending) is Kingdom, Phylum (Division for plants), Class, Order, Family, Genus, Species. Option D is ascending order from species to kingdom and is also correct. The question asks for the correct order; B is descending and D is ascending. I'll adjust to ask for descending: rephrase. I'll make a new question that avoids duplication. I'll skip this one.

Explanation:
Solar energy is captured by photosynthetic autotrophs and converted to chemical energy, which then flows through food chains. Except for deep-sea hydrothermal vents relying on chemosynthesis, the sun powers virtually all life on Earth.
