The traits for blood type and Rh are the result of the presence or absence of particular on the erythrocytes.g
just olya [345]

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.

1. How did you revise your sequence from your initial idea ? Explain how you decided on the sequence. For the Natural Selection
liberstina [14]

Natural selection is the idea that  organisms that posses favorable traits that enable them to survive in their environment are the ones that live long enough to pass on these traits to their offspring.

<h3>What is natural selection?</h3>

The question is incomplete but I will try my best to explain the idea of natural selection.

The term natural selection refers to the idea put forward by Charles Darwin that organisms that posses favorable traits that enable them to survive in their environment are the ones that live long enough to pass on these traits to their offspring. This is also called the survival of the fittest.
