what is the difference between a positive and a negative blood?
138771
The blood groups being positive and negative is defined by the presence or absence of certain antigens on the surface of RBCs. If this surface has antigen then it is called as positive if the surface does not have antigen then it is called a negative blood group. The antigen present is known as RH antigen or rhesus .

The presence or absence of A or B antigens gives us four main blood types: A type blood has only A antigens on red blood cells. B type blood has only B antigens on red blood cells. AB has both A and B antigens on red blood cells.

A type blood has only A antigens on red blood cells. B type blood has only B antigens on red blood cells. AB has both A and B antigens on red blood cells. O has neither A nor B antigens on red blood cells.

Each person has two Rh factors in their genetics, one from each parent. The only way for someone to have a negative blood type is for both parents to have at least one negative factor. For example, if someone's Rh factors are both positive, it is not possible for his or her child to have a negative blood type.

Blood types are determined by the presence or absence of particular antigens on the surface of red blood cells. There are eight main blood types: A positive, A negative, B positive, B negative, AB positive, AB negative, O positive and O negative. The positive and negative refers to your Rh type (once called Rhesus).

A red blood cell (RBC) count is a blood test that tells you how many red blood cells you have. Red blood cells contain a substance called haemoglobin, which transports oxygen around the body.

But positive and negative do not represent the quality of the factor being added or removed. That factor can be pleasant or unpleasant. For instance, positive can be adding something unpleasant resulting in unpleasant feelings, while negative can be removing something unpleasant resulting in pleasant feelings.

Negative and positive decimals can be compared just like fractions. Decimals are a part of a whole just like fractions are a part of a whole. Therefore, a positive decimal is ALWAYS greater than a negative decimal. When you have two negative decimals, the one closer to zero is always greater.

Rule 2: A negative number times a positive number equals a negative number. When you multiply a negative number to a positive number, your answer is a negative number. It doesn't matter which order the positive and negative numbers are in that you are multiplying, the answer is always a negative number.

What It Means to Have A Positive (A+) Blood Type. If your blood is A positive (A+), it means that your blood contains type-A antigens with the presence of a protein called the rhesus (Rh) factor. Antigens are markers on the surface of a blood cell.

O negative red blood cells lack the A and B antigens (hence, group O) and also the Rh(D) antigen. Rh null blood lacks all the antigens in the Rh group, such as D, C, c, E, e and others. The Rh null red cells can still be positive for A or B antigens, the presence or absence determines their ABO blood type.

Positive or negative blood If you have the Rh D antigen, your blood type is positive. If you lack the Rh D antigen, your blood type is negative.

Your blood can be Rh positive, which means that you have the Rh protein, or Rh negative, which means that you do not have the Rh protein. The letter of your blood group plus the Rh makes your blood type. You can be O+, O−, A+, A−, B+, B−, AB+, or AB−.

The value of numbers get decreases by moving towards left from 0 while it increases while moving right to zero. Hence Positive Numbers (including Zero too) are always Greater than the Negative numbers. Though, 2 is greater than 1, but negative sign before 2 ( i.e. - 2) makes it smaller than 1.

The negative of a negative is the opposite positive number. When you subtract a positive integer from a negative integer, the difference is always negative. ... When you subtract two negative integers and the first integer (or minuend) is larger than the second integer (or subtrahend), the difference is positive.

Positive numbers are bigger, greater, or higher than zero. ... Negative numbers are smaller than zero. Negative numbers get smaller and smaller the farther they are from zero. This can get confusing because you may think that –400 is bigger than –12.

Technically there is no difference between positive and negative G's, they just act in the opposite vector direction from each other relative to an object. As such, whether a G-force is positive or negative is entirely determined by the object upon which the forces are acting.
