Year 10 Biology - Diseases

Explanation
Diseases can be transmitted through direct contact with an infected person or animal, such as shaking hands or sexual contact. Contaminated food and water can also spread diseases when consumed, as they may contain harmful bacteria or viruses. Vectors, such as mosquitoes or ticks, can transmit diseases by biting and transferring pathogens from one host to another. Therefore, it is important to be cautious and take preventive measures to avoid these modes of disease transmission.

Explanation
The correct answer is antibiotics, vaccinations, hygiene, antiseptics/disinfectants, and food preservation. These methods help prevent the spread of diseases. Antibiotics are used to treat bacterial infections, while vaccinations help build immunity against specific diseases. Practicing good hygiene, such as washing hands regularly, can prevent the transmission of pathogens. Antiseptics and disinfectants kill or inhibit the growth of microorganisms, reducing the risk of infection. Lastly, food preservation techniques, such as refrigeration or canning, help prevent the growth of bacteria and other harmful microorganisms in food.
