Rhinoceros unicornis is the binomial name of the Indian one-horned rhinoceros. Panthera uncia is the snow leopard, Elephas maximus the Asian elephant, Gavialis gangeticus the gharial. The genus Rhinoceros and species unicornis reflect its single horn. Binomial nomenclature ensures universal scientific recognition.
Explanation:
The Fluid Mosaic Model is the universally accepted model for the structure of the plasma membrane. It was proposed by S. Jonathan Singer and Garth Nicolson in 1972. It describes the membrane as a dynamic, fluid lipid bilayer in which globular proteins are embedded (integral) or attached to the surface (peripheral), creating a 'mosaic' pattern. The lipids and proteins can move laterally within the plane of the membrane. Danielli and Davson proposed the earlier 'sandwich model'.
Explanation:
The nephron is the microscopic structural and functional unit that filters blood and forms urine. It consists of the renal corpuscle (glomerulus + Bowman's capsule) and tubules. Alveoli are lung units, neurons are nerve cells, hepatocytes are liver cells. Each kidney contains about one million nephrons.
Explanation:
The IUCN Red List (Red Data Book) documents the conservation status of plants, animals, and fungi, categorizing species from Extinct to Least Concern. It highlights species at risk of global extinction. It is a critical tool for conservation policy and action. Endangered species like the Bengal tiger and snow leopard are listed. The Red Data Book was first published by IUCN in 1964.
