The organ of the human body that filters blood and forms urine is the: MCQ with Answer and Explanation

Explanation:
The Leghorn (specifically the White Leghorn) is a highly popular and productive breed of chicken originating from Tuscany, Italy. It is primarily reared as a layer breed for commercial egg production due to its high egg yield, early maturity, and efficient feed conversion. It is not typically used for meat production (broilers like Cornish Cross are preferred for that) or as cattle. Rhode Island Red is another dual-purpose breed, but Leghorn is specifically famous for eggs.

Explanation:
Mitochondria produce ATP through oxidative phosphorylation in the inner membrane. They are double-membrane organelles with their own DNA (mtDNA) and 70S ribosomes, supporting the endosymbiotic theory. The Krebs cycle occurs in the mitochondrial matrix. Nucleus controls cell activities, ribosomes synthesize proteins, Golgi apparatus packages and modifies proteins. Mitochondria are abundant in energy-demanding cells like muscle cells.

Explanation:
Smooth endoplasmic reticulum (SER) lacks ribosomes and is the site of lipid synthesis, including phospholipids and steroids. It also detoxifies drugs and poisons. Rough ER synthesizes proteins, Golgi modifies and packages molecules, lysosomes degrade waste. SER is abundant in cells producing steroid hormones.
