71. Movement of water molecules from the area of higher water potential to the area of lower water potential called?

پانی کے انووں کی زیادہ پانی کی پوٹینشل کے علاقے سے کم پانی کی پوٹینشل کے علاقے میں حرکت جسے ____ کہتے ہیں؟

Check answer and explanation

Answer: Osmosis

Explanation Osmosis is the movement of water molecules from an area of higher water potential (high concentration of water molecules) to an area of lower water potential (low concentration of water molecules) through a selectively permeable membrane. This process helps to equalize the concentration of water molecules on both sides of the membrane.

ایک بار جب آپ کے پاس ڈیٹا ہو جائے تو آپ کو _____ تجزیہ کرنے کی ضرورت پڑ سکتی ہے۔

Check answer and explanation

Answer: Mathematical

Explanation Once you have the data , you may need to perform mathematical analysis. It involves using statistical and mathematical techniques to interpret and draw conclusions from the data.

73. A group of similar cells combine together to form _____?

ملتے جلتے خلیوں کا ایک گروپ مل کر _____ بناتا ہے؟

Check answer and explanation

Answer: Tissue

Explanation A group of similar cells that perform a specific function combine to form tissue . Tissues then combine to form organs . Organs work together to form systems .

74. Splitting of glucose (glycolysis) release small amount of energy which is enough to generate _____?

گلوکوز کی تقسیم (گلائیکولائسز) تھوڑی مقدار میں توانائی خارج کرتی ہے جو _____ پیدا کرنے کے لیے کافی ہے؟

Check answer and explanation

Answer: 2 ATP

Explanation Glycolysis, the splitting of glucose , releases a small amount of energy that is enough to generate 2 ATP (adenosine triphosphate) molecules. This process occurs in the cytosol of cells and is the first step in cellular respiration.
