Top 100 Biology GK Questions

Vitamin A deficiency can lead to night blindness and poor vision. B vitamins are a class of water-soluble vitamins. Vitamin B refers to several different types of vitamins that, together, are known as the B-complex vitamins. The commonly used Vitamin B Complex is constituted of 8 vitamins. Thiamin (vitamin B-1) Riboflavin (vitamin B-2) Niacin (vitamin B-3) Pantothenic acid (vitamin B-5) Vitamin B-6 Biotin (vitamin B-7) Folate (vitamin B-9) Vitamin B-12 Deficiency of Vitamin C can cause scurvy, a disease that is characterised by bleeding gums, skin spots, and swelling in joints. It also affects the immune system and can even be fatal in acute conditions. Vitamin C has been shown to enhance iron absorption. It captures non-heme iron and stores it in a form that's more easily absorbed by your body. Foods high in vitamin C include citrus fruits, dark green leafy vegetables, bell peppers, melons and strawberries. Citrus fruits are an excellent source of vitamin C. So from the above points, we can say that- 'X' = Vitamin C 'Y' = Iron (mineral) 'Z' = (Food) Citrus fruits

Metal 'X' displaces metal 'Y' from its salt solution, so 'X' is more reactive than 'Y'. Metal 'X' Can not displace metal 'Z' from its salt solution, so 'Z' is more reactive than 'X'

Species that are restricted to a particular geographical area are called endemic species.

Found mainly in the state of Meghalaya, India's only pitcher plant species Nepenthes khasiana is endangered, facing threats from mining, shifting cultivation, and excessive collection, among others. N. khasiana is distributed in the Garo, Khasi, and Jaintia Hills.

Diploid Sporosity:

The embryo sac, the master spore, is derived from the mother cell either directly by mitosis or by inhibiting meiosis. An eight-nucleated embryo sac is formed. This is a common process in plants like corn and wheat.

Pituitary gland: It is a small pea-sized gland. It is often called the master gland as it controls several other hormone glands in our body. It is located in the brain between Hypothalamus and the Pineal gland. So, the pituitary gland in human beings secretes more than three hormones.

Symptoms of vitamin B12 deficiency or folate deficiency anemia develop slowly and are similar to those of other types of anemia, such as fatigue, weakness, and pale skin. Vitamin B12 deficiency can also cause nerve damage, the main symptoms of which include tingling, loss of touch, and muscle weakness. Confusion can arise when Vitamin B12 becomes too low. Vitamin B12 deficiency anemia in the elderly can be mistaken for dementia. This happens because of similar symptoms.

1. All the creatures of Echinodermata phylum are marine and have thorny bodies.

2. There is a mass flow system in their body.

3. A specific water-conveying canal system is found, which helps in their movement.

1. Fungal enzymes decompose simple inorganic substances.

2. Fungi are a type of microorganisms that decompose organic matter.

3. Enzymes break down organic matter into smaller molecules, which can then be used by the body of the fungus.
