Final Answer:
1. Can be passed through genes to family members:
- Infectious (No)
- Noninfectious (Yes)
2. Can be spread by vectors:
- Infectious (Yes)
- Noninfectious (No)
3. Can be caused by poor diet:
- Infectious (No)
- Noninfectious (Yes)
4. Can be transmitted through physical contact with an infected person:
- Infectious (Yes)
- Noninfectious (No)
Step-by-step explanation:
In the realm of genetic transmission, noninfectious diseases can indeed be passed through genes to family members. Conditions like certain types of cancer, diabetes, and cardiovascular diseases often have a hereditary component. On the contrary, infectious diseases are not typically inherited genetically but rather spread through pathogens like bacteria or viruses.
The spread by vectors, such as mosquitoes or ticks, is a characteristic primarily associated with infectious diseases. Diseases like malaria and Lyme disease are examples where vectors play a crucial role in transmitting the causative agents. Noninfectious diseases, lacking a microbial origin, are not transmitted through vectors.
Poor diet is a significant factor in the development of many noninfectious diseases, including obesity, type 2 diabetes, and cardiovascular diseases. In contrast, infectious diseases are not primarily caused by dietary habits but rather result from exposure to infectious agents.
The transmission through physical contact is a hallmark of many infectious diseases. Respiratory infections like the flu or common cold can spread through contact with infected individuals. Noninfectious diseases, however, do not typically transmit through physical contact, as they arise from factors unrelated to infectious agents.
