22. The dough of bread rises because of:

Correct Answer: (2) Growth of yeast cells
Solution:The dough of bread rises because of the growth of yeast cells.
  • Yeast is a single celled fungus that eats sugar and produces carbon dioxide gas as a byproduct.
  • The carbon dioxide gas gets trapped in the dough by the gluten, which is a protein that is formed when flour and water are mixed and kneaded.
  • As the yeast cells grow and produce more carbon dioxide gas, the dough expands and rises.

Solution:Tin cans are nonbiodegradable, while the other op tions are biodegradable.
  • Biodegradable materials are materials that can be broken down by natural processes. such as bacteria and fungi.
  • Wood, woolen clothes, and paper are all biodegradable materials.
  • They will eventually decompose into harmless substances, such as carbon dioxide and water.
  • Non-biodegradable materials are materials that cannot be broken down by natural processes.

24. Tiger is a_______because it only eats meat.

Correct Answer: (1) Carnivore
Solution:A carnivore is an animal that eats meat. Tigers are car-nivores because they only eat meat.
  • They are apex predators. meaning that they are at the top of the food chain and have no natural predators.

28. When a white light passes through a prism, a spectrum Is observed. Which colour of light bends most?

Correct Answer: (3) Violet
Solution:When a white light passes through a prism, it is refracted, meaning that it bends as it passes through the prism.
  • The different colors of light that make up white light bend at different angles, resulting in a spectrum of colors.
  • Violet light bends the most, followed by indigo, blue, green. yellow, orange, and red.
  • This is because violet light has the shortest wavelength. and the shorter the wavelength, the more the light bends.
  • Red light has the longest wavelength, and the longer the wavelength, the less the light bends.

29. The blood has_______which fight against germs that may enter our body.

Correct Answer: (4) White blood Carpuscles
Solution:White blood cells, also known as leukocytes, are the body's primary defense against infection.
  • They play a crucial role in the immune system by identifying and destroying foreign Invaders, such as bacteria, viruses, and fungi.

  • Haemoglobin is a protein in red blood cells that carries oxygen.

30. For the process of rusting of Iron, the presence of which is required?

Correct Answer: (2) Water and Oxygen both
Solution:Rusting is the process of iron combining with oxygen and water to form a reddish brown substance called rust. The chemical reaction for rusting is: Fe(s) + O₂(g) + H₂O(l) → Fe₂O₃(s)xH₂O(l)
  • Oil will not cause iron to rust. In fact, it can protect iron from rusting by forming a barrier between the iron and the air.
  • Water alone will not cause iron to rust. However, it can accelerate the rusting process if oxygen is also present.
