اٹھارہ سو انہتر میں منڈیلیف نے _____ کے بارے میں اپنا متواتر قانون پیش کیا؟
A. Atomic Number
B. Atomic Mass
C. Chemical properties
D. Physical properties
Check answer and explanation
Answer: Atomic Mass
Explanation In 1869, Dmitri Mendeleev proposed his periodic law , which states: "When the elements are arranged in order of increasing atomic mass , certain sets of properties recur periodically ." This law allowed him to create the first periodic table , where elements were arranged in a logical order based on their atomic masses and chemical properties.
مندرجہ ذیل میں سے کون سا خاکہ دکھاتا ہے کہ ایٹم ایک ہی برقی منفیت کے ساتھ جڑے ہوئے ہیں؟
A. A -----:----- B
B. A :---------- B
C. A ----------: B
D. A --:-------- B
Check answer and explanation
Answer: A -----:----- B
Explanation The diagram that shows atoms are bonded with the same electronegativity is: A -----:----- B. In this representation, the bond is shown with a symmetrical distribution of electrons. It suggesting that the atoms have the same or very similar electronegativity.
سینٹریول بنانے کے لیے ایک خاص پیٹرن میں ترتیب دیے گئے مائیکرو ٹیوبولس _____ تعداد میں ہوتے ہیں۔
A. 26
B. 27
C. 23
D. 25
Check answer and explanation
Answer: 27
Explanation Centrioles are composed of 27 microtubules arranged in a specific pattern of nine triplets (9 x 3 = 27). These microtubules are highly stable and form a rigid structure that plays a critical role in the formation of cilia , flagella, and spindle fibers during cell division.
اگر بہار آسانی سے پھیلتی ہے تو اس کی بہار کا مستقل _____ ہوتا ہے؟
A. Both (a) and (b)
B. Large value
C. Constant Value
D. Small value
Check answer and explanation
Answer: Small value
Explanation If a spring stretches easily , it means that it requires less force to stretch it a certain distance. This is indicative of a spring with a small spring constant (k). The spring constant is a measure of a spring's stiffness. A smaller value means the spring is less stiff and more easily deformed.
Explanation An example of a true solution is Ink in water. In a true solution, the solute particles are completely dissolved and cannot be seen or separated by filtration , which is characteristic of ink dissolved in water.
Explanation All species are given scientific names , also known as binomial nomenclature or Latin names. This system was developed by Carolus Linnaeus. It is used universally by biologists and scientists to identify and classify species.
Explanation The foundation of life is based on chemical processes and reactions that occur within living organisms. These chemical reactions involve the building blocks of life. Such as carbon, hydrogen, oxygen, nitrogen, and phosphorus. They are combined in various ways to form biomolecules like carbohydrates, proteins, and nucleic acids.
Explanation Weight is a vector quantity Because it is a force defined as the product of mass and the acceleration due to gravity ( W = mg). It has both magnitude (amount of force) and direction (downward, towards the center of the Earth) Additional information Mass, Time, and temperature are scalar quantities Last updated on 09-03-2026
وہ جانور جو مستقبل میں معدوم ہونے کے خطرے سے دوچار ہیں؟
A. Extinct
B. Vulnerable
C. Endangered
D. Threatened
Check answer and explanation
Answer: Endangered
Explanation Endangered species are animals, plants , or fungi that are at risk of becoming extinct in the near future. They are threatened by various factors , such as habitat loss, pollution, climate change, overhunting, and human activities.
ایک جسم غیر جانبدار توازن میں ہوتا ہے جب اس کی کشش ثقل کا مرکز _______ ہے؟
A. Remains at same height
B. Is at its base
C. Is at highest position
D. Is at the lowest position
Check answer and explanation
Answer: Remains at same height
Explanation Neutral equilibrium is a state where the body is balanced , but the slightest disturbance will not cause it to return to its original position or topple over. In this state, the center of gravity (CG) remains at the same height , regardless of the slight tilt or displacement. Key Points : A body is in unstable equilibrium after slight tilt if its center of gravity remains above the point of contact. A body is in stable equilibrium after slight tilt if its center of gravity remains above the point of contact.
