The most common cause of anemia is low levels of iron in the body. This type of anemia is called iron-deficiency anemia. Your body needs a certain amount of iron to make hemoglobin, the substance that moves oxygen throughout your body.

In rare cases in the United States or in other parts of the world where nutritional diets may vary, vitamin A deficiency can also lead to night blindness. Vitamin A, also called retinol, plays a role in transforming nerve impulses into images in the retina. The retina is a light-sensitive area in the back of your eye.

Starch testing

Iodine solution is used to test leaves for the presence of starch.

Natural barriers include the skin, mucous membranes, tears, earwax, mucus, and stomach acid. Also, the normal flow of urine washes out microorganisms that enter the urinary tract. The immune system uses white blood cells and antibodies to identify and eliminate organisms that get through the body's natural barriers.

Fiber is one kind of carbohydrate. It is sometimes called roughage or bulk. Fiber is the part of plant foods that our bodies do not break down during digestion. Because fiber isn't digested, it doesn't give us calories.

Answer 2

(B) Proteins are present in sesame seeds.

Anaemia is caused by the deficiency of (B) iron.

We lose vision due to deficiency of (D) Vitamin D.

Solution used for testing starch is (A) Iodine.

The substances that offer protection against diseases are (C) Vitamins and minerals.

(C) Beverages are a kind of carbohydrates that our body fails to digest.

Explanation:

• Protein, vitamin B1, dietary fibre and phosphorus, iron, magnesium, calcium, manganese, copper, and zinc are all abundant in sesame seeds.
• Anemia is caused by a deficiency of iron, which occurs frequently as a result of blood loss or pregnancy.
• Vitamin D deficiency can also have a harmful effect on eye health. Age-related macular degeneration, diabetic retinopathy, uveitis, dry eye syndrome and reduced tear function have all been linked to vitamin D insufficiency.
• Adding iodine solution (yellow/brown) to starch and watching for a colour change is a chemical test for starch. Iodine turns a blue/black colour when exposed to starch.
• Vitamins and minerals are two substances that help to keep the body healthy.
