6) a quantity representing the amount of water vapour in the atmosphere

7)a red protein responsible for transporting oxygen in the blood of vertebrates

8)it is an instrument used for showing the direction of the wind

Answer 2

Answer:

1)Anemometer : An anemometer is an instrument used to measure the speed of the wind, which is a common weather station instrument, or to calculate any form of current gas.

2)Hydrometer: An instrument for determining the specific gravity of a liquid, commonly consisting of a graduated tube weighted to float upright in the liquid whose specific gravity is being measured.

3)Compound: A substance formed from two or more elements chemically united in fixed proportions.

4)Indicators: Indicators are substances whose solutions change color due to changes in pH. These are called acid-base indicators.

5)Excretion : Excretion is the process that biological organisms use to expel or eliminate the waste products produced by their metabolisms.

6)Humidity: The amount of water vapour in the air. It is the most variable characteristic of the atmosphere and constitutes a major factor in climate and weather

7) Haemoglobin: Hemoglobin is a protein in red blood cells that carries oxygen. The hemoglobin test measures how much hemoglobin is in your blood.

8)Wind Vane : A wind vane is a device that measures the direction of the wind. The wind vane is usually combined with the anemometer. Wind direction is the direction from which the wind is blowing.
