• Ribosomes are tiny cell structures that make proteins.
• They read genetic instructions from RNA to assemble amino acids into proteins.
• Ribosomes are found in both plant and animal cells, either free in the cytoplasm or attached to the endoplasmic reticulum.

• Ronald Ross discovered that malaria is transmitted by mosquitoes in 1897.
• He showed that the Anopheles mosquito carries the malaria parasite from person to person.

• Urbanization is the process of people moving to cities and towns, leading to their growth.

It increases the demand for housing, roads, and infrastructure.

• Agriculture is the practice of growing crops and raising animals for food and resources.

It often requires clearing land, which can impact forests and natural habitats.

• Rising sea levels
• Extreme weather events like floods, storms, and heatwaves
• Melting glaciers and loss of biodiversity
• 
  

These effects result from long-term changes in temperature and weather patterns.

• Displacement is the change in position of an object from its initial point to its final point.
• It is a vector quantity, meaning it has both magnitude and direction.
• Displacement shows the shortest straight-line distance between two points.

• Stock value is related to economics and finance, not physics.
• Physics deals with matter, energy, motion, and forces.
• Therefore, stock value is not a term used in physics.

• The solvent commonly used in soft drinks is water.
• It dissolves sugar, flavors, and carbon dioxide in the drink.
• Water makes up the largest portion of soft drinks.

• The study of agriculture is called Agricultural Science or Agronomy.
• It deals with crop production, soil management, and farming techniques.
• This field helps improve food quality and increase agricultural yield.

• There are 31 pairs of spinal nerves in the human body.
• They arise from the spinal cord and carry sensory and motor signals.
• These nerves connect the brain with different parts of the body.

• Herbivores eat plant-based diets, which are high in cellulose and difficult to digest.
• To maximize nutrient absorption, their small and large intestines are long, coiled, and folded.
• Examples of herbivores: cow, goat, horse, rabbit.
