Explanation

Mutualism is a type of symbiotic relationship where both organisms benefit from each other's presence.

Examples of mutualism include:

• The birds that ride on large buffalos and elephants
• Honeybees visit male and female flowers for nectar and pollen, and the flowers get pollinated.

Explanation

• Nitrogen (N2) is the most abundant constituent in air.
• Making up approximately 78% of the Earth's atmosphere.

The correct order of abundance:

• Nitrogen (N2) - 78%
• Oxygen (O2) - 21%
• Argon (Ar) - 0.93%
• Carbon Dioxide (CO2) - 0.04%

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

• Asteroids are irregularly shaped solid objects composed primarily of rocks and metals.
• They are found mainly in the asteroid belt between Mars and Jupiter.

Explanation

• When sound waves reach the ear drum, it vibrates and causes the small bones (ossicles) behind the eardrum to vibrate.
• These vibrations are then transmitted to the liquid in the inner ear (cochlea).
• Where they are detected by small hairs (hair cells) and converted into electrical signals that are sent to the brain via the auditory nerve.

Explanation

• Crystallization is the process of obtaining a solid substance from a solution by allowing the solution to cool and form crystals.
• This process is used to purify substances and obtain a solid in a pure form.

Explanation

Abiotic components refer to the non-living things in an environment, including:

• Physical elements: light, temperature, water, soil, air
• Chemical elements: minerals, nutrients, salts
• Geological elements: rocks, minerals, terrain

Explanation

• Carbon dioxide (CO2) is the gas from the atmosphere that plants absorb through their leaves.
• It use as a reactant in photosynthesis, combining it with water and light energy to produce glucose and oxygen.
