Answer 1

Answer:

1. The statement is True.
2. The statement is False.
3. The statement is True.
4. The statement is True.
5. The statement is False.

Explanation:

• The first statement is true/correct because gases like oxygen, ammonia and carbon dioxide are water- soluble. Examples of water-soluble gases are: Carbon dioxide, ammonia, chlorine, sulfur dioxide, and hydrogen sulfide.
• The second statement is false/incorrect because Goitre is caused by the deficiency of iodine and not by the deficiency of iron. The deficiency of iron actually causes anemia.
• The third statement is true/correct as swelling and tenderness at the injury site is significant in sprains and it often includes severe discoloration of the skin mainly blue and black or purplish-black.
• The fourth statement is true/correct as composition of sedimentary rocks consists of sandstones, pebbles, mud and clay of varying size.
• The fifth statement is false/incorrect as when river flows through plains When it enters the plains, it banks gets wider, it deepens and steepness and slopes are reduced, which decreases the speed of water thereby slowing down the pace of flow.
