ایلومینیم کا 1 جی مساوی وزن ____ کے برابر ہے؟
Answer: 9 g
Explanation The equivalent weight of an element is the mass of the element that reacts with one mole of electrons (or one mole of hydrogen atoms). For aluminum (Al), the equivalent weight is 9 g. Atomic weight of Al = 27 g/mol Valency of Al = 3 (since Al forms Al3+ ions) Equivalent weight = Atomic weight / Valency = 27 g/mol / 3 = 9 g So, 1 g equivalent weight of Al is 9 g!
ڈھانچے میں مختلف افعال ہوتے ہیں (فزیالوجی) لیکن ان کا اندرونی فن تعمیر ایک جیسا ہوتا ہے۔ _____
Answer: Homologous
Explanation Homologous structures are those that have different functions (physiology) but share similar internal architecture or morphology , indicating a common evolutionary origin. Examples include: Forelimbs of vertebrates (e.g., human arms, bird wings, whale flippers) Pelvic bones of different mammals
پورے عرصے میں تحفظ کا اثر ______ ہے؟
Answer: Decrease
Explanation The shielding effect decreases across a period. This is because the increasing nuclear charge is not fully counterbalanced by the same number of inner electrons, resulting in a weaker shielding effect.
روشنی پر منحصر ردعمل ______ میں ہوتا ہے؟
Answer: Thylakoid
Explanation The light-dependent reactions (also known as the Hill reaction) occur in the thylakoid membranes of the chloroplast. Thylakoids are specialized membranous structures found in chloroplasts, where light energy is absorbed and converted into ATP and NADPH.
مندرجہ ذیل میں سے کون سا کم کرنے والا ایجنٹ ہے؟
Answer: Al
Explanation Aluminum (Al) is a metal that can easily lose electrons to form ions, making it a reducing agent. As a reducing agent, aluminum can donate electrons to other substances, causing them to be reduced.
سمندری غذا پروٹین کا ایک بہترین ذریعہ ہے کیونکہ یہ عام طور پر ______ میں کم ہوتا ہے؟
Answer: Fats
Explanation Seafood is an excellent source of protein because it is typically low in fats (lipids) and high in protein. Many types of seafood, such as fish and shellfish, are lean sources of protein, making them a popular choice for those looking to reduce their fat intake.
