Explanation

 Flagella are long, whip-like structures that help bacteria move.

Cilia are found in some eukaryotic cells (not bacteria).

Pseudopodia are used by amoebas (not bacteria).

Pili are used for attachment and DNA transfer, not movement.

Explanation

The plants and vegetation of a region are collectively known as flora.

Flora refers to the plant life occurring in a particular region or time. 

Explanation

Blade → The flat, leaf-like part

Stipe → The stem-like structure

Holdfast → Anchors the organism to a surface (like a root)

These are characteristic parts of macroscopic algae (especially brown algae like Laminaria or Sargassum).

Explanation

 In bacterial cells, RNA makes up about 6% of the total cell weight, which is relatively high compared to DNA due to the abundance of ribosomal RNA (rRNA).

Explanation

Micronutrients are essential elements required by organisms in small quantities for proper growth and development.

Among the options:

• Manganese, Iodine, Zinc, and Iron are all recognized micronutrients for humans and plants.

• Sodium, Magnesium, and Sulfur are considered macronutrients because they are required in larger amounts.

Explanation

Explanation

Blubber is a thick layer of fatty tissue found under the skin of whales, seals, and other marine mammals.

It acts as insulation against cold temperatures in ocean water and also serves as an energy reserve.

Explanation

For deep-sea diving, oxygen is mixed with helium (forming heliox) to prevent nitrogen narcosis and oxygen toxicity at high pressures.

Helium is inert, light, and doesn't cause narcotic effects under pressure like nitrogen does.
