پروٹین فیکٹریوں سے پروٹین کی پیداوار کے صحیح راستے کا پتہ لگائیں؟
A. RER → Ribosome → Lysosome → Golgi body
B. RER → Ribosome → Golgi body → Lysosome
C. Ribosomes → RER → Golgi body → Lysosome
D. Golgi body → RER → Ribosome → Lysosome
Check answer and explanation
Answer: Ribosomes → RER → Golgi body → Lysosome
Explanation The correct order is : Ribosomes → RER → Golgi body → Lysosome. Ribosomes : Protein synthesis occurs here , and the newly synthesized protein is released into the cytosol. RER (Rough Endoplasmic Reticulum) : The protein is transported to the RER , where it is processed and modified (e.g., folding, glycosylation). Golgi body : The protein is packaged into vesicles and transported to the Golgi body, where it is further modified and sorted. Lysosome : The protein is delivered to lysosomes , where it can be used for various cellular processes (e.g., digestion, recycling).
ویکٹر کی مقدار میں میگنیٹیوڈ اور یونٹ کے ساتھ _____ ہوتا ہے۔
A. Magnitude
B. Direction
C. None of them
D. Both a and b
Check answer and explanation
Answer: Both a and b
Explanation Definition: Possess both magnitude and direction. Representation : Represented by arrows, where the length indicates magnitude and the arrowhead indicates direction. Examples: Displacement Velocity Acceleration Force Momentum Additional information Difference from Scalars: Unlike scalars, which only have magnitude (e.g., speed), vectors require both to be fully defined Last updated on 09-03-2026
Explanation Carbon dioxide (CO2) reacts with calcium hydroxide (Ca(OH)2. It is also known as lime water to form a white precipitate of calcium carbonate (CaCO3), which turns the solution milky : Ca(OH)2 + CO2 → CaCO3 + H2O This reaction is often used as a test for carbon dioxide.
جانداروں میں توانائی ایک خاص مالیکیول میں ذخیرہ ہوتی ہے جسے _____ کہتے ہیں؟
A. DNA
B. NADH
C. ATP
D. RNA
Check answer and explanation
Answer: ATP
Explanation ATP (Adenosine Triphosphate) is a molecule that stores energy in the form of phosphate bonds. It is often referred to as the " energy currency " of the cell, as it can be easily converted into other forms of energy that are needed by the cell.
Explanation A solid has a fixed shape and a definite volume , regardless of its container. The particles ( molecules, atoms, or ions ) in a solid are closely packed and have a fixed position, giving the solid its rigidity and shape.
مائع میں، کچھ توانائی بخش مالیکیول سطح سے آزاد ہو جاتے ہیں یہاں تک کہ جب مائع بلبلوں کے بننے کے لیے بہت ٹھنڈا ہو۔ اس عمل کا نام کیا ہے؟
A. Boiling
B. Condensation
C. Evaporation
D. Convection
Check answer and explanation
Answer: Evaporation
Explanation Evaporation is the process by which molecules escape from the surface of a liquid to become vapor, even if the liquid is below its boiling point. This occurs when some molecules have enough energy to break free from the surface tension of the liquid and turn into vapor. Key Points: Boiling occurs when a liquid is heated to its boiling point , causing bubbles to form and rise to the surface. Condensation is the process by which vapor is converted back into a liquid. Convection is the transfer of heat through the movement of fluids.
Explanation Selenium (Se) is a metalloid , which means it exhibits some properties of metals and some properties of nonmetals. Metalloids are elements that are intermediate in character between metals and nonmetals.
Explanation Heat is a form of energy , specifically thermal energy , which is transferred from one body to another due to a temperature difference. It is a type of kinetic energy , where the particles of a substance vibrate or move rapidly, generating heat.
خوردبین ایک ایسا آلہ ہے جسے _____ بصری تصویر بنانے کے لیے ڈیزائن کیا گیا ہے۔
A. Enlarged
B. Magnified
C. Illuminated
D. Inverted
Check answer and explanation
Answer: Magnified
Explanation Microscopes are instruments designed to produce magnified visual images of small objects or samples. It allowing us to see details that are not visible to the naked eye.
مصنوعی رالیں ان جگہوں پر استعمال ہوتی ہیں جہاں _______؟
A. Water resistance is required
B. Friction is required
C. Electric resistance is required
D. Adhesion is required
Check answer and explanation
Answer: Adhesion is required
Explanation Synthetic resins are used in places where adhesion is required. They provide strong bonding properties , making them ideal for coatings, glues, and composite materials.
