Explanation

• Decomposers are organisms that break down dead and waste products, releasing useful elements such as carbon, nitrogen, and phosphorus back into the soil and environment.
• This process is called decomposition, and it's an essential step in the nutrient cycle.

Decomposers include organisms like:

• Bacteria
• Fungi (such as mushrooms)
• Detritivores (such as earthworms and insects)

By breaking down organic matter, decomposers help to:

• Recycle nutrients
• Improve soil structure and fertility
• Support plant growth and development

Explanation

• The odd one out is: Ratio
• Theory, Law, and Hypothesis are all related to the scientific method.

Explanation

Explanation

• Sugar (a solid) dissolves in water (a liquid) to form a solution, making it a classic example of a solid-liquid solution.
• The sugar molecules (solute) are dissolved in the water molecules (solvent), resulting in a homogeneous mixture.

Explanation

In flowering plants, xylem is composed of four types of tissues:

1. Tracheids
2. Vessel elements
3. Xylem fibers
4. Xylem parenchyma

Explanation

Starch is a type of carbohydrate that is quickly digested by the body.

It is a complex carbohydrate made up of long chains of glucose molecules.

It found in foods such as bread, pasta, and potatoes.

Explanation

The cell cycle is also known as the cell division cycle.

It is the sequence of changes that occurs between one cell division and the next.

Explanation

The particle that comprises two protons and two neutrons is an alpha particle (α).

Alpha particles are emitted from the nucleus of an atom during a type of radioactive decay called alpha decay or α-emission.

Explanation

A battery is connected in an electric circuit to provide a constant potential difference (voltage) across the circuit, allowing electric current to flow through the conductors.

The battery maintains a constant voltage, ensuring a consistent flow of current through the circuit.

Explanation

The presence of a dielectric material between the plates of a capacitor increases the capacitance of the capacitor.

The dielectric material reduces the electric field between the plates, allowing more charge to be stored on the plates, and thus increasing the capacitance.
