Answer:

Protozoans can be parasitic. Malaria is the most significant of the protozoan parasites that infect humans. Malaria is found in tropical and sub-tropical regions of the world. In addition, tropical countries are often affected by poverty, poor sanitation, and inadequate medical facilities. These factors often increase the transmission of parasitic diseases.

Two species of meadowlarks have different mating calls that lead to reproductive isolation. What type of isolation does this exa
77julia77 [94]
Hi there!

The example of the meadowlarks is an example of behavioral isolation. This is because the mating call is a behavior the birds exhibit. This helps the birds to find their correct mate because though the birds look similar, they are not able to produce offspring.

Hope this helps!! :)

An air mass forms over the North Pole region describe what you think the temperature and humidity of this air mass will be like?
soldi70 [24.7K]

Answer: hope this helps :)

The motion of air mass motion is usually based upon the air flow in the upper atmosphere. As the jet stream changes intensity and position, it affects the motion and strength of air masses. Where air masses converge, they form boundaries called "fronts".

3-D view of a cold front.

Fronts are identified by change of temperature based upon their motion. With a cold front, a colder air mass is replacing a warmer air mass. A warm front is the opposite affect in that warm air replaces cold air. There is also a stationary front, which, as the name implies, means the boundary between two air masses does not move.

The motion of air masses also affects where a good portion of precipitation occurs. The air of cold air masses is more dense than warmer air masses. Therefore, as these cold air masses move, the dense air undercuts the warmer air masses forcing the warm air up and over the colder air causing it to rise into the atmosphere.

So, fronts just don't appear at the surface of the earth, they have a vertical structure or slope to them as well. Warm fronts typically have a gentle slope so the air rising along
