Explanation

During metaphase, homologous chromosomes (pairs of chromosomes that contain the same genes) arrange themselves on the equator of the spindle, also known as the metaphase plate.

This is a critical step in the cell division process, ensuring that each daughter cell receives a complete set of chromosomes.

Explanation

Chromosomes are thread-like structures that appear during cell division, specifically during the prophase stage of mitosis or meiosis.

They are made up of condensed chromatin and carry genetic information from one generation of cells to the next.

Explanation

Biodiversity refers to the degree of variation within or among species.

Including genetic, species, and ecosystem diversity, across different regions of the Earth.

Explanation

Bu Ali Sina (Avicenna), a renowned Persian physician and polymath, identified various diseases, including tuberculosis and meningitis.

In his seminal work "The Canon of Medicine".

Explanation

• An ecosystem is a specific area where living organisms (the community) interact with each other and their non-living environment (such as water, air, soil, sunlight, and temperature).
• It's a self-contained system where living and non-living components work together to create a functional unit.

Explanation

Suckers are shoots that arise from buds on the base of a parent plant, often at the soil line or just below.

They are a type of vegetative propagation, allowing the plant to produce new stems and roots.

Suckers can grow into new individuals, eventually forming a clump or colony.

Explanation

The cerebellum is responsible for:

• Coordinating movements
• Maintaining posture and balance
• Regulating muscle tone
• Learning new motor skills
• Precision and accuracy in movements

Explanation

• Animals that migrate long distances need a compact and energy-dense source of fuel to sustain them during their journey.
• Fat is the most energy-dense nutrient, providing approximately 9 kcal/g, compared to carbohydrates (4 kcal/g) and protein (4 kcal/g).

Explanation

• Chemical reactions require specific conditions to proceed at a proper rate.
• Temperature and pressure are two of the most important factors that influence reaction rates.

Explanation

They can be reshaped – False.

While cartilage is flexible, it does not permanently change shape without surgical intervention or long-term external force (like in orthodontics or ear reshaping).

It’s not inherently reshaping like soft tissues.
