• Vaccination involves administering a weakened or killed pathogen to stimulate an immune response in the body. This process allows the immune system to recognize the pathogen and produce antibodies against it.
• As a result, if the person is exposed to the actual pathogen in the future, their immune system can respond quickly and effectively to prevent infection.

Carbohydrates are the primary source of quick energy for our body. When we eat foods rich in carbohydrates, our body breaks them down into glucose, which provides us with the energy we need for various activities.

A deficiency of vitamin C can lead to a condition known as scurvy.

• Scurvy is caused by a lack of vitamin C in the diet.
• Symptoms include fatigue, swollen gums, joint pain, and bleeding from the skin.
• It is preventable by consuming adequate amounts of fruits and vegetables like oranges and strawberries.

Beriberi is not a communicable disease. It is primarily caused by a deficiency of vitamin B1 (thiamine). The main points to understand are:

• Beriberi results from inadequate nutritional intake.
• It can occur in individuals with poor diets, particularly those lacking in whole grains and meat.
• The condition affects the nervous system and cardiovascular health.
• It is not spread from person to person.

In summary, beriberi is a nutritional deficiency rather than an infectious disease.

Beriberi is caused by a deficiency of vitamin B1 (thiamine), not vitamin C. Vitamin B1 plays a crucial role in converting carbohydrates into energy and supporting nerve function. A deficiency of vitamin B1 can lead to symptoms such as fatigue, weakness, nerve damage, and cardiovascular problems.

The substance that does not contain fat is water.

Vaccinations are an effective way to prevent diseases like typhoid, polio, and tetanus. These diseases can indeed be prevented through vaccination programmes.

• Typhoid: Vaccines are available and recommended for those travelling to areas where typhoid is common.
• Polio: Widespread vaccination has nearly eradicated polio globally.
• Tetanus: Regular tetanus vaccinations are crucial to prevent this disease, often given in combination with other vaccines.

Therefore, the statement that these diseases cannot be prevented by vaccination is false.

A deficiency in Vitamin B can lead to a condition known as Beriberi.

• Beriberi is associated with a lack of Vitamin B1, also known as Thiamine.
• This deficiency affects the body's ability to convert carbohydrates into energy.
• Symptoms include weakness, nerve degeneration, and heart problems.

• Brushing your teeth twice a day helps maintain oral hygiene.

• This practice prevents tooth decay and maintains gum health.

A lack of proteins and carbohydrates in the body leads to malnutrition.

• Malnutrition occurs when the body doesn't get enough nutrients.
• It can result in various health issues like stunted growth, weakness, and a weakened immune system.
• Both proteins and carbohydrates are essential for energy and body repair.

Measles is a highly contagious communicable disease caused by the measles virus. It spreads through respiratory droplets from coughing and sneezing of an infected person.
