Do you dream of securing a permanent government job in Indian Railways?<\/strong> The RRB Group D exam<\/a><\/strong> is your golden ticket to a stable career. But as you know, the competition is huge and, if you want to stand out from that competition, then you are required to do a lot of study and preparation. After an in-depth analysis, we have found that life science is one of the most important subjects because it can give you at least 10-12 marks in the exam. Many students from non-science backgrounds get scared of difficult biological names like “Mitochondria” or “Xylem.” But they don’t know that they don’t need to be a doctor to answer these questions. The exam asks very simple things about our own body, plants, and diseases. For example, “Which vitamin helps in blood clotting?” or “What is the powerhouse of the cell?” These are facts you can easily memorize. To help you prepare for this subject effectively, we have provided the most important and repeated Life Science questions for RRB Group D exam in a free PDF.<\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n In the General Science section (25 questions), Life Science is one of the most important subjects.

(a) Vitamin A
(b) Vitamin B
(c) Vitamin C
(d) Vitamin D
Answer:<\/strong> (c) Vitamin C
Logic:<\/strong> Vitamin C is Ascorbic Acid. Its deficiency causes Scurvy<\/strong>. It is found in citrus fruits like lemons and oranges.<\/p>\n\n\n\n
(a) Nucleus
(b) Mitochondria
(c) Ribosome
(d) Lysosome
Answer:<\/strong> (b) Mitochondria
Logic:<\/strong> Mitochondria generate energy (ATP) for the cell, just like a power plant generates electricity for a city.<\/p>\n\n\n\n
(a) Mouth
(b) Stomach
(c) Small Intestine
(d) Large Intestine
Answer:<\/strong> (b) Stomach
Logic:<\/strong> Digestion starts in the mouth for carbohydrates, but protein digestion begins in the stomach<\/strong> with the help of the enzyme Pepsin<\/strong>.<\/p>\n\n\n\n
(a) Xylem
(b) Phloem
(c) Stomata
(d) Cortex
Answer:<\/strong> (a) Xylem
Logic:<\/strong> Remember: Xylem = Jal (Water)<\/strong> and Phloem = Food (Phal)<\/strong>. Xylem carries water from roots to other parts of the plant.<\/p>\n\n\n\n
(a) A Positive
(b) B Positive
(c) AB Positive
(d) O Negative
Answer:<\/strong> (d) O Negative
Logic:<\/strong> O Negative blood has no antigens, so it can be given to anyone. AB Positive<\/strong> is the universal recipient.<\/p>\n\n\n\n
(a) Thyroid
(b) Pituitary
(c) Adrenal
(d) Pancreas
Answer:<\/strong> (b) Pituitary
Logic:<\/strong> The Pituitary gland, located in the brain, controls the functioning of almost all other endocrine glands.<\/p>\n\n\n\n
(a) Vitamin A
(b) Vitamin D

(a) Typhoid
(b) Cholera
(c) Tuberculosis (TB)
(d) Dengue
Answer:<\/strong> (d) Dengue
Logic:<\/strong> Dengue is caused by a virus transmitted by mosquitoes. Typhoid, Cholera, and TB are bacterial diseases.<\/p>\n\n\n\n
