وزن کم کرنے کی حکمت عملی کے طور پر لپڈز کو ذخیرہ کرنے کا نقصان _____ ہے؟
A. None of these
B. Restricts swimming ability
C. Linked with metabolism
D. Only solution for bottom dwellers
Check answer and explanation
Answer: Linked with metabolism
Explanation Storing lipids for buoyancy is linked with metabolism , It means the lipids can be consumed as energy, reducing buoyancy over time. This strategy may not provide long-term buoyancy stability if energy demands are high.
C. Testis in male and ovaries in female developed from the same embryonic tissue
D. None of the above
Check answer and explanation
Answer: Wings of bat and bird
Explanation Analogous organs have similar functions but different evolutionary origins. Wings of a bat (mammal) and a bird (avian) serve the same function (flight) but evolved independently .

A. Conservation biology
B. Community ecology
C. None of these
D. Restoration ecology
Check answer and explanation
Answer: Restoration ecology

Explanation Trilobites are an extinct group of marine arthropods that lived during the Paleozoic Era. They are one of the earliest known groups of arthropods.
B. SPSS (Statistical Package for the Social Sciences)
C. QGIS (Quantum Geographic Information System)
D. SAS (Statistical Analysis System)
Check answer and explanation
Answer: QGIS (Quantum Geographic Information System)
