GinnyAnswer
To determine which antibodies are present in the blood stream of an individual with O positive (O+) blood type, we need to understand the basic principles of blood types and antibodies:

1. Blood Types and Antigens:
- Blood types are determined by the presence or absence of specific antigens on the surface of red blood cells.
- For type O blood, there are no A or B antigens on the surface of the red blood cells.

2. Antibodies in Plasma:
- The plasma of the blood contains antibodies that react against foreign antigens.
- For individuals with type O blood, both anti-A and anti-B antibodies are present in their plasma since their red blood cells do not have either A or B antigens.

3. Rh Factor:
- The "positive" in O+ refers to the presence of the Rh factor (D antigen) on the red blood cells. This does not affect the presence of A or B antibodies in the plasma.

Given this understanding, we can conclude:

- Individuals with O+ blood have neither A nor B antigens on their red blood cells.
- Therefore, their plasma will contain both anti-A antibodies and anti-B antibodies.

The answer to the question is:

A and B antibodies
