Answer 1

Answer:

1. It is vital to wind speed, because the greater the difference in pressure, the faster the wind flows (from the high to low pressure) to balance out the variation. The pressure gradient, when combined with the Coriolis effect and friction, also influences wind direction

2. Chromatography

3. Only one chromosome is seen

4. bone

5. Cyanobacteria 

6. Gases have very low density as compared to liquids and solids. So they do not possess high density.
