Explanation

• Insects like bees, butterflies, moths, and beetles are important pollinators of plants in gardens.
• They visit flowers to collect nectar and pollen, and in the process, transfer pollen from one flower to another, allowing for fertilization to occur.

Explanation

• In plants, water and minerals are transported from the roots to the leaves through the xylem.
• A type of vascular tissue.

Explanation

• In the human heart, blood returning from the lungs via the pulmonary veins drains into the left atrium.
• From there, it flows through the mitral valve into the left ventricle, which pumps it out to the rest of the body through the aorta.

Explanation

• Athlete's foot is a common fungal infection caused by fungi such as Trichophyton, Epidermophyton, and Microsporum.
• Rashes can be caused by various factors, including fungal infections. For example, ringworm (a fungal infection) can cause a rash.

Explanation

Evolution theory explains that the world and living beings follow a natural order and regularity through gradual changes over time.

It is primarily associated with Charles Darwin, who proposed that species evolve through natural selection.

Explanation

• The female reproductive part of a flower is called the Pistil.

It consists of three parts:

1. Stigma (receives pollen grains)
2. Style (connects stigma to ovary)
3. Ovary (contains ovules/eggs)

The pistil is also sometimes referred to as the carpel, which is a modified leaf that forms the female reproductive organ.

Explanation

Primary consumers are animals that eat producers (plants) and are the first level of consumers in a food chain. They are also known as herbivores. Examples of primary consumers include:

• Insects (bees, butterflies, ants)
• Small mammals (cows, goats, rabbits, mice, squirrels)
• Birds (finches, sparrows, robins)
• Fish (some species of fish that eat algae or aquatic plants)

Explanation

The K orbit, also known as the first electron shell.

• It can hold a maximum of 2 electrons.

The L orbit, also known as the second electron shell.

• It can hold a maximum of 8 electrons.

The M orbit, also known as the third electron shell.

• It can hold a maximum of 18 electrons.

Explanation

Lowland plains cover more than 50% of the Earth's crust, including river valleys and coastal areas.

These regions are fertile and densely populated, supporting agriculture and human settlements.

Explanation

Carbon Dioxide is responsible for fermentation.

During fermentation, microorganisms like yeast convert sugars into alcohol and carbon dioxide as byproducts.
