2. Hyperplasia
3. Hypertrophy
4. Dysplasia
5. Anaplasia

Answer 1

The replacement of one adult tissue type by another in the respiratory tubes due to smoking is called metaplasia. Smoking can cause numerous health problems including cancer, heart disease, and respiratory diseases.

Step-by-step explanation:

The phenomenon where one adult tissue type is replaced by another within the respiratory tubes as a result of smoking is called metaplasia.

This is a potentially dangerous change because it can lead to dysplasia and eventually cancer.

Smoking causes a wide range of harmful effects on the body, which include but are not limited to increased risks of cancer, heart disease, respiratory diseases like chronic obstructive pulmonary disease (COPD), peripheral vascular disease, emphysema, and others.

Tobacco smoke contains many carcinogens and toxic chemicals that can cause significant damage to the respiratory system, cardiovascular system, and overall health.
