Why Skin Comes In Colors I have read an article on Why skin comes in colors" by Blake Edgar‚ and he gives a brief analysis of why that is so. According to my research‚ skin color is largely determined by the amount of melanin the skin produces. Dark-skinned individuals produce more melanin than light-skinned individuals. At least three genes regulate the amount of melanin produced. Each gene has two forms: dark-skin allele (A‚ B‚ and C) and light-skin allele (a‚ b‚ and c). Neither allele

Environmental determinism‚ also known as climatic determinism or geographical determinism‚ is the view that the physical environment sets limits on human environment. Historiography [edit] Origins [edit] Environmental determinism’s origins go back to antiquity‚ where it is first encountered in a fifth-century medical treatise ascribed to Hippocrates: Airs‚ Waters‚ Places.[1] In Roman times it is‚ for example‚ found in the work of the Greek geographer Strabo who wrote that climate influences the

Question 5 What is the primary reason that astronomers suspect that some jovian moons were captured into their current orbits? Some moons have orbits that are "backwards" (compared to their planet’s rotation) or highly inclined to their planet’s equator. Question 6 The region of our solar system between Mercury and Mars has very few asteroids‚ while the region between Mars and Jupiter has many asteroids. Based on what you have learned‚ what is the most likely explanation for the lack of asteroids

His works include the Āryabhaṭīya (499 CE‚ when he was 23 years old)[5] and the Arya-siddhanta. The works of Aryabhata dealt with mainly mathematics and astronomy. He also

Rotation on its axis ‚Its rotation period at its equator is 25 earth days And at its poles‚ it is35 earth days. 2. Circular movement among its neighboring stars and constellations. it travels at 250 Km/sec PLANETS The planets are formed at various distances from sun. they are independent on each other

present to become part of the planetary formation. The surface of Mercury is extremely hot. It is approximately 470 degrees Celsius on the surface and is thought to be even hotter at the two hot spots. These hot spots are on opposite ends of the equator. It is the heat of the surface that makes it impossible for Mercury to have any type of atmosphere. Mercury orbits the sun once every 88 days and has a true rotation period of 58.6 days. Venus is the second closest planet to the sun and is said

offers many positive environmental conditions for a base. Located just south of Mars’ equator‚ the Valles Marineris is a system of canyons nearly 4000 kilometers long‚ between fifty and one hundred kilometers wide‚ and up to ten kilometers deep (Valles Marineris‚ n.d.). The Valles Marineris offers monumental scientific opportunity to study Mars’ strata. Because of the Valles Marineris proximity to the equator‚ it will provide more consistent periods of day versus night time and a more consistent

Biography Name While there is a tendency to misspell his name as "Aryabhatta" by analogy with other names having the "bhatta" suffix‚ his name is properly spelled Aryabhata: every astronomical text spells his name thus‚[1] including Brahmagupta’s references to him "in more than a hundred places by name".[2] Furthermore‚ in most instances "Aryabhatta" does not fit the metre either.[1] [edit] Birth Aryabhata mentions in the Aryabhatiya that it was composed 3‚600 years into the Kali Yuga‚ when
