Answer:
Answer is that phagocytes could not attach as easily to invading microbes.
Step-by-step explanation:
C3 and C5 are regarded as examples of complements. And the deficiency of these complements is regarded as hypocomplementamia, which is an immunodeficiency.
Phagocytes are cells in the body that are protecting the body by engulfing or ingesting harmful foreign particles such as bacteria and other small dead cells.
The deficiency of C3 will not allow the phagocytes to carry out their activities against the invading microbes. This means that, Charlie and Rachelle are exposed to bacterial infections.
