The right answer is AB-.

In humans, the blood group is determined by the substances on the surface of the red blood cells, called antigens. Blood groups are grouped into systems. In the ABO system, there are four possible blood groups: A, B, O, and AB. In the Rh system, the presence or absence of substance "D" on the surface of the red blood cell determines whether Rh is positive (+) or negative (-).

The combination of the two systems allows classification into 8 blood groups: groups: A +, A-, B +, B-, AB +, AB-, O + and O-.

A Rh- subject can only receive Rh- blood, but a Rh + subject can receive Rh + but also Rh- since the latter does not possess rhesus antigen. therefore if we do not know the rhesus of the subjects we can transfuse Rh-blood without risk (Biensur with ABO compatibility).

What happens to salinity if the rate of evaporation is greater than precipitation? Why?​
malfutka [58]

Answer:

Answer:

Explanation:

What happens when water's salinity increases?

A combination of high salinity and low temperature makes seawater so dense that it sinks to the bottom of the ocean and flows across ocean basins as deep, slow currents.

What happens to local salinity when evaporation rates increase?

Salinity is the saltiness of seawater. Salinity is measured by the concentration of grams of salt per kilogram of water. ... What happens to local salinity when evaporation rates increase: Rises 5.

How is salinity related to evaporation and precipitation?

Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
