Answer 1

### Effects of Cystic Fibrosis
The most accurate option regarding the effects of cystic fibrosis is:
**Respiratory and digestive issues.**
Cystic fibrosis primarily affects the lungs and digestive system, leading to thick mucus that can cause obstructive lung disease and interfere with nutrient absorption.

### Accurate Definition of Mutation
The most accurate definition of mutation is:
**D. A mutation is a change in DNA that can change the structure and function of genetic information.**
This definition encompasses the broader implications of mutations, which can lead to both beneficial adaptations and detrimental conditions, including various diseases.

### Mutation That Causes Abnormal Cell Division
A mutation that causes abnormal cell division can result in:
**Skin cancer.**
Abnormal cell division is a hallmark of cancer, and mutations that disrupt normal regulatory mechanisms can lead to uncontrolled cell growth and subsequently tumor formation, particularly in skin cells.
