Answer 1

Correct Answer: By bacteria and viruses that attack our body

Rationale:

Diseases and illnesses are often caused by pathogens, which are microorganisms such as bacteria and viruses that invade and multiply within the human body, leading to infections and various health issues.
Bacteria are single-celled organisms that can cause diseases such as strep throat, tuberculosis, and urinary tract infections. They can be harmful, but some bacteria are beneficial and necessary for bodily functions.
Viruses are smaller than bacteria and require living hosts, such as humans or animals, to multiply. They cause diseases like the common cold, flu, HIV/AIDS, and COVID-19 by hijacking the host's cellular machinery to reproduce.
These pathogens can enter the body through various means, including inhalation, ingestion, or breaks in the skin, and the immune system responds to fight off the infection.

Explanation of Other Options:

By vaccinations at a too early age

Rationale: Vaccinations are designed to prevent diseases, not cause them. They work by stimulating the immune system to recognize and combat pathogens without causing the disease itself. Administering vaccines at the recommended age is crucial for effective immunity.

By antibodies that get into our body

Rationale: Antibodies are proteins produced by the immune system to neutralize or destroy pathogens. Their presence in the body indicates an immune response to fight infections, not the cause of illnesses. They help protect against future infections.

None of these

Rationale: This option is incorrect as diseases and illnesses are indeed caused by bacteria and viruses, which are well-established and scientifically proven causes of many infectious diseases.

Conclusion:

Diseases and illnesses are primarily caused by bacteria and viruses that invade and multiply within the body, leading to infections. Vaccinations and antibodies play crucial roles in preventing and fighting infections, respectively, and are not causes of diseases.
