In the water cycle, infiltration is most closely related to:
water table |
|
rivers |
|
oceans |

Someone who has Rh-factor __________ blood cannot receive blood with a __________ type.
antigen, negative |
|
negative, positive |

positive, antigen |

Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.

As a cold front moves into an area, the heavier cool air __________ the lighter warm air that it is replacing.
mixes with |
|
cancels out |
|
pushes above |
|
pushes under |
A cold front is a warm-cold air boundary with the colder air replacing the warmer. As a cold front moves into an area, the heavier cool air pushes under the lighter warm air that it is replacing. The warm air becomes cooler as it rises and, if the rising air is humid enough, the water vapor it contains will condense into clouds and precipitation may fall.
