What causes air masses to move?

Biology

A difference in air pressure and temperature occurs. While weather conditions CAN affect air mass movement, a mixture of cold and warm air masses (which have differences in air pressure and temp) cause jet streams and more directly affect the movement of air masses. As a cold air mass builds, the temperature gradient between the cold air mass and the warmer air outside the air mass will increase. This increases the upper level winds which in turn helps steer an air mass away from its source region.

Vesnalui [34]

Answer:

The correct answer is BB genotype and BO genotype.

Explanation:

The human blood system or ABO system shows codominance due to the multiple alleles. That means three different alleles for human blood type are present are IA, IB, and i. For easy understanding can be stated as A (for IA), B (for IB), and O (for i).

If someone has blood type B could have a genotype of either BB or BO because of the dominance of B allele on O where is If A allele present with B allele it would show co-dominance.

Thus, the correct answer is the BB genotype and BO genotype.
