From the mother through the placenta
NACL is the correct answer
The best answer would be, 'The warmer the air temperature, the greater the humidity.'
The second choice is true, but the graph is representing humidity, not precipitation. That is off-topic.
C could also be true, but the chart didn't refer to any body of water.
I hope this helped you!
Brainliest answer is always appreciated!
Answer: Antigens
Explanation: The ABO system of blood grouping is based on the basis of the type of antigens that are present in the red blood cells. Erythrocytes is another name for the red blood cells. Antigens are molecules that are capable of eliciting immune response. There are two types of antigens: antigen A and B. Blood type A has only antigen A, blood type B has only antigen B, blood type AB has both antigen A and B while blood type O has no antigen (neither A nor B antigen).
Similarly, Rh trait is determined by the presence or absence of rhesus antigen in the erythrocytes. Rhesus antigen is an antigen first discovered in rhesus monkey. Rh+ indicates the presence of rhesus antigen in the red blood cells while Rh- indicates the absence of rhesus antigen in the red blood cells.
