A. Restocking
B. Reintroduction
C. None of the above
D. Augmentation
Check answer and explanation
Answer: Reintroduction
Explanation Purpose of Reintroduction Programs : These programs aim to stabilize, reestablish , or increase animal populations in their natural habitats. Source of Animals : Animals are raised or rehabilitated in AZA-accredited zoos or aquariums. Reason for Reintroduction : Populations targeted for reintroduction have suffered significant declines . Method : Animals are released into their natural habitats as part of conservation efforts.

زیادہ سے زیادہ درجہ حرارت جس پر ریشمی کیڑے کے انڈے نکلتے ہیں ______ ہے؟
A. None of these
B. 65-70°F
C. 65-75°F
D. 60-70°F
Check answer and explanation
Answer: 65-75°F
Explanation The optimum temperature for the hatching of silk moth eggs is between 65-75°F . This temperature range ensures favorable conditions for the eggs to hatch into larvae.
Explanation The centromere is the region of a chromosome where spindle fibers attach during cell division. It ensures the proper movement and segregation of chromosomes during mitosis and meiosis.
Explanation Intrinsic value of biodiversity refers to its inherent worth . It independent of human use or benefit. It emphasizes the moral and ethical obligation to preserve all forms of life.

D. Separate the organelles to determine their functions
Check answer and explanation
Answer: Separate the organelles to determine their functions
Explanation Cell fractionation isolates cellular organelles to study their structure and function individually. This process involves centrifugation to separate components based on size and density.
Explanation Chromosomes become distinctly visible as condensed structures during prometaphase in mitosis. This stage follows prophase , and the nuclear envelope begins to break down.
مندرجہ ذیل میں سے کون سا طریقہ تحفظ کے لیے ان سیٹو طریقہ نہیں ہے؟
A. Agroecosystem
B. Field gene banks
C. None of these
D. National Park
Check answer and explanation
Answer: Field gene banks
Explanation Field gene banks are ex-situ methods, as they store genetic material outside natural habitats. In-situ conservation involves protecting species in their natural environments, such as national parks and agroecosystems.
