مندرجہ ذیل میں سے کون سا آکسائڈائزنگ ایجنٹ کے طور پر کام کرتا ہے؟
Answer: Cl
Explanation Chlorine (Cl) is a strong oxidizing agent. It means it can accept electrons from other substances and cause them to be oxidized.
کون سا عمل سیل کے اندر اور باہر نقل و حرکت کی اجازت دیتا ہے؟
Answer: All of these
Explanation All three processes allow movement in and out of cells: Osmosis : Movement of water molecules from high concentration to low concentration through a selectively permeable membrane. Diffusion : Random movement of molecules from high concentration to low concentration until equilibrium is reached. Active transport : Movement of molecules from low concentration to high concentration using energy (ATP) to pump molecules across the cell membrane.
متواتر جدول کو _______ کی بنیاد پر ایس، پی، ڈی، اور ایف بلاک میں تقسیم کیا گیا ہے؟
Answer: Electronic Configuration
Explanation The periodic table divided into S, P, d, and f block based on Electronic Configuration. S block : The s block includes the first two columns of the periodic table, which are the alkali and alkaline earth metals. P block : The p block includes the elements in the six columns on the right side of the periodic table. D block : The d block includes the elements in the ten columns in the middle of the periodic table. These are also known as the transition metals . F block : The f block includes the elements at the bottom of the periodic table, which are known as the inner transition metals or lanthanides and actinides.
مخصوص مسکن میں رہنے والے مختلف انواع کے ارکان کو ____ کہتے ہیں؟
Answer: Community
Explanation A community refers to all the different species living in a specific habitat or area, interacting with each other and their environment.

متواتر جدول میں چوتھے اور پانچویں دور کو کیا کہا جاتا ہے؟
Answer: Long period
Explanation The 4th and 5th periods in the periodic table are known as the long periods. These periods contain 18 elements each , making them the longest periods in the periodic table. Important Points: Short periods : 1st and 2nd periods (2 and 8 elements, respectively) Long periods : 4th and 5th periods (18 elements each) Normal periods : 3rd and 6th periods (8 and 12 elements, respectively)
کی عددی قدر ہر جگہ مستقل رہتی ہے۔ _____
Answer: G
Explanation The numerical value of G (the gravitational constant) remains constant everywhere in the universe, regardless of the location, time, or conditions. G is a fundamental constant of nature that describes the strength of gravitational attraction between objects.
Answer: 13 N
Explanation The vertical component of the force is: Vertical component = Force × sin(angle) = 15 N × sin(60°) = 15 N × 0.866 = 13 N So, the vertical component of the 15 N force at an angle of 60° is approximately 13 N.
آئنک کرسٹل میں ______ ہے؟
Answer: High melting points
Explanation Ionic crystals are typically characterized by high melting points due to the strong electrostatic forces between the positively and negatively charged ions. The attractive forces between oppositely charged ions are strong, requiring a significant amount of energy to overcome , resulting in high melting points.
ایک جسم توازن میں ہے جب اس میں ______ ہے؟
Answer: Zero acceleration
Explanation A body is in equilibrium when the net force acting on it is zero, and it is not changing its motion. This means that the body is either at rest or moving with a constant velocity (uniform speed), but not accelerating.
Answer: 98.8%
Explanation Carbon-12 (C-12) is the most abundant of the two stable isotopes of carbon, amounting to 98.93% of elemental carbon on Earth. Carbon-12 is composed of six protons , six neutrons, and six electrons. The atomic mass of carbon-12 is exactly 12 Dalton's, by definition.
