The iron-containing protein in RBCs that transports oxygen is: MCQ with Answer and Explanation

Explanation:
Ex-situ (off-site) conservation involves protecting endangered species outside their natural habitats. Zoological parks, botanical gardens, seed banks, and cryopreservation facilities are examples of ex-situ conservation. This method allows for controlled breeding, research, and education, and can be a last resort for species whose natural habitats are severely degraded or destroyed.

Explanation:
Cloning produces genetically identical copies of an organism or cell. In animals, somatic cell nuclear transfer (like Dolly the sheep) is used. Plant cloning occurs via vegetative propagation or tissue culture. Hybridization combines different genomes; mutation breeding induces mutations; cross breeding involves mating. Cloning has applications in therapeutics, conservation, and agriculture.

Explanation:
Glomerular filtration rate (GFR) is the volume of filtrate formed per minute by both kidneys, normally about 125 mL/min (180 L/day). Nearly 99% of the filtrate is reabsorbed, leaving about 1-2 liters of urine per day. GFR is regulated by the juxtaglomerular apparatus. It's an important clinical indicator of kidney function, estimated from serum creatinine.
