Physics Chemistry & Biology Test 2
The materials through which the object can be seen but not clearly are known as?
  • Transparent
  • Translucent
  • Transferable
  • Transformable
Explanation:

Translucent materials allow light to pass through but scatter it, making objects on the other side visible but not clear. Examples include frosted glass and wax paper.

Jute is mainly grown in which region?
  • Andhra Pradesh
  • Telangana
  • West Bengal
  • Gujarat
Explanation:

Jute is indeed mainly cultivated in the eastern and northeastern regions of India, with West Bengal being the largest producer, contributing significantly to the country’s overall jute production. Assam, Bihar, Odisha, Tripura, and Uttar Pradesh also play important roles in jute cultivation. Jute thrives in the warm, humid climate of these regions, making it suitable for large-scale farming.

Fibers which are not obtained from plant or animal sources are called as?
  • Artificial Fibers
  • Natural Fibers
  • Synthetic Fibers
  • Cellulosic Fibers
Explanation:

Synthetic fibers are those that are not derived from natural plant or animal sources but are instead made through chemical processes, such as nylon, polyester, and acrylic.

Fibers obtained from plants and animals are called?
  • Artificial Fibers
  • Natural Fibers
  • Synthetic Fibers
  • Cellulosic Fibers
Explanation:

Natural fibers are those derived from plant (such as cotton, jute, and linen) or animal sources (such as wool, silk, and alpaca).

Iron deficiency may cause?
  • Anemia
  • Rickets
  • Scurvy
  • Goiter
Explanation:

Iron deficiency can lead to anemia, a condition where the body lacks enough healthy red blood cells due to insufficient iron, resulting in fatigue and weakness.

Which of the following are the symptoms of anemia?
  • Headaches
  • Weakness
  • Hairfall
  • All of the above
Explanation:

Anemia symptoms include headaches, weakness, and hairfall. Headaches occur due to reduced oxygen supply to the brain, while weakness arises from insufficient red blood cells to transport oxygen throughout the body. Hairfall can result from nutrient deficiencies associated with anemia. Recognizing these symptoms is essential for timely diagnosis and treatment.

Iodine deficiency causes?
  • Goiter
  • Explanation:

    Iodine deficiency causes goiter, an enlargement of the thyroid gland. Insufficient iodine affects thyroid hormone production, leading to this condition, which can result in various metabolic and developmental issues.
