a.
increasing the density of the parcel

b.
reducing the pressure of the parcel

c.
increasing the temperature of the parcel

d.
increasing the mixing ratio of the parcel

e.
both c and d will increase the virtual temperature of the parcel

C.  Increasing the temperature of the parcel

D.  Increasing the mixing ratio of the parcel

Both C and D will increase the virtual temperature of the parcel

Explanation:

A change in temperature of the air can likewise change the relative moistness. Dew Point is the temperature to which a package of air must be cooled, at steady weight and water vapor content, for immersion to happen. Dew point is resolved regarding a level surface of the water.

Supreme moistness is equivalent to the mass of water vapor partitioned by the complete volume of air or water vapor thickness. Total stickiness changes as the volume of air package changes.

the wrong statement is - c. a desert had more biodiversity than a marsh.

the deserts are one of the places of the planet where there's the least biodiversity. the reasons for that are the climate and the lack of food sources, which hampers both the number of the species that can survive in it, and the number of the individuals in the species itself.

the marshes, on the other hand, are places where there's perfect conditions for lots of organisms to thrive. the temperature is moderate and nice, the amount of water and the food sources are on a high level, so there's an abundance of both plant and animal life in them.
