Explanation

Potential divider is a circuit that gives us continuously varying potential.

Examples of the potential dividers are Rheostat and Potentiometer

Explanation

The burning of substances in air or oxygen on heating, with the release of a large amount of heat energy and light energy, is called combustion

while

In conduction, heat transfer occurs between objects by direct contact.

In convection, the heat transfer takes within the fluid

Condensation is the process by which water vapor in the air is changed into liquid water; it's the opposite of evaporation

Fungi often enter plant tissues through natural openings like stomata, which are small pores on the surface of leaves. 

Explanation

• Yeast is a type of fungus that consumes sugars and produces carbon dioxide gas, causing dough to rise.
• It is a microorganism that is essential for fermentation in bread making.

Explanation

• A pair consists of two equally opposite forces acting on two different but parallel lines of action.
• The moment of  force depends on the distance from the fulcrum and the magnitude of the force, but the moment of the pair is the net effect of the two moments of force.
  

Explanation

 Prokaryotic cells lack membrane-bound organelles like chloroplasts.

Chloroplasts are organelles found in eukaryotic cells, specifically plant cells, and are responsible for photosynthesis.

Prokaryotic cells, while simpler in structure, do possess other components such as"

• Ribosomes (for protein synthesis)
• A cell wall (for structural support)
• DNA (although not contained within a nucleus)
