The apple tree (Malus domestica) is a deciduous tree in the rose family best known for its sweet,pomaceous fruit, the apple. It is cultivated worldwide as a fruit tree, and is the most widely grown species in the genus Malus. The tree originated in Central Asia, where its wild ancestor, Malus sieversii, is still found […]
Kelps are large seaweeds (algae) belonging to the brown algae (Phaeophyceae) in the orderLaminariales. There are about 30 different genera.[citation needed] Kelp grows in underwater “forests” (kelp forests) in shallow oceans, and is thought to have appeared in the Miocene, 23 to 5 million years ago.[2] The organisms require nutrient-rich water with temperatures between 6 […]
Modern humans (Homo sapiens or Homo sapiens sapiens) are the only extantmembers of the homininclade, a branch of great apes characterized by erect postureand bipedal locomotion; manual dexterity and increased tool use; and a general trend toward larger, more complex brains and societies.[3][4] Early hominids, such as theaustralopithecines whose brains and anatomy are in many […]

Frogs are a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura(Ancient Greek an-, without + oura, tail). The oldest fossil “proto-frog” appeared in the early Triassic of Madagascar, but molecular clock dating suggests their origins may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, […]
In molecular biology and bioinformatics, SNP array is a type of DNA microarray which is used to detect polymorphisms within a population. Asingle nucleotide polymorphism (SNP), a variation at a single site in DNA, is the most frequent type of variation in the genome. Currently, there are around 85 million SNPs that have been identified […]
