Explanation

Plants uptake nutrients from all three sources:

• Air: carbon dioxide (CO2) and oxygen (O2) through photosynthesis
• Water: dissolved nutrients and minerals through their roots
• Soil: nutrients and minerals like nitrogen, phosphorus, potassium, and others through their roots

Explanation

Mating between distantly related individuals is known as outbreeding.

This practice helps increase genetic diversity and reduce the chances of hereditary diseases.

Explanation

• Meiosis is a type of cell division that produces four non-identical daughter cells, each with half the number of chromosomes as the parent cell.
• This process is essential for sexual reproduction, as it allows for the mixing of genetic material from two parents and the creation of genetically diverse offspring.

Explanation

• Meiosis is the process by which sex cells (sperm and egg cells) are divided and gametes are formed during reproduction in humans.
• Meiosis involves two successive cell divisions (meiosis I and meiosis II) that result in four non-identical daughter cells, each with half the number of chromosomes as the parent cell.

Explanation

• Fertilization is the process where a male gamete (pollen) fuses with a female gamete (ovule) to form a zygote.
• It develops into a seed and eventually a new plant.

Explanation

• 6CO2 + 6H2O → C6H12O6 + 6O2
• This is the correct equation for photosynthesis, where carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) in the presence of light energy.

Explanation

• The Cochlear Nerve, also known as the Auditory Nerve.
• It carries sound information from the cochlea of the inner ear directly to the brain.
• It is responsible for transmitting electrical signals from the cochlea to the brain, where they are interpreted as sound.

Explanation

• Vacuoles are small, membrane-bound sacs found in the cytoplasm of cells, which contain air, liquid, or food particles.
• They play a role in storage, digestion, and maintenance of cellular homeostasis.

Explanation

• A food chain is a series of organisms that eat and are eaten by each other, showing the flow of energy and nutrients from one organism to another.
• It represents the relationship of eating and being eaten among organisms in an ecosystem.

Explanation

• Kwashiorkor is a disease that occurs when a diet has an inadequate amount of protein relative to carbohydrates, leading to an imbalance.
• This imbalance can cause swelling, fatigue, and poor growth, and typically affects older children.
