Answer 1

Here's a hint to help you fill in the chart:

1. **Understanding Blood Types**: Blood types are determined by the presence of specific antigens on the surface of red blood cells. The main blood group antigens are A, B, and Rh (D).

2. **Antibodies**: The body produces antibodies against the antigens that are not present in its own blood type. For example, a person with blood type A will have A antigens and will produce antibodies against B antigens.

3. **Rh Factor**: The presence or absence of the Rh factor (D antigen) is also important. If the Rh factor is present, the blood type is positive (e.g., A+), and if it's absent, the blood type is negative (e.g., A-).

4. **O Blood Type**: Blood type O has no A or B antigens and is considered a universal donor, but it produces antibodies against both A and B antigens.

Using these hints, you can now fill in the details in the chart based on the known blood type compatibility rules. Here’s a quick guide for reference:

- **Type A**: Antigens - A; Antibodies - anti-B
- **Type A+**: Antigens - A, D; Antibodies - anti-B
- **Type B**: Antigens - B; Antibodies - anti-A
- **Type B+**: Antigens - B, D; Antibodies - anti-A
- **Type AB**: Antigens - A, B; Antibodies - none
- **Type AB+**: Antigens - A, B, D; Antibodies - none
- **Type O**: Antigens - none; Antibodies - anti-A, anti-B
- **Type O+**: Antigens - D; Antibodies - anti-A, anti-B
