Multiple Choice

During a biology class, Ms. Serrano noticed that Michael had a scab on his hand. Shakira and London were curious about how the scab formed. They wondered what role genes play in this process. Can you help them understand?

• Genes provide instructions for making proteins that aid in scab formation

• Genes regulate blood flow to the wound area

• Genes produce antibodies to fight off infection at the wound site

• Genes control hormone production that influences scab formation
