Tabellaria), or stars (e.G. Asterionella). The first diatom officially defined in medical literature, the colonial Bacillaria paradoxa, was discovered in 1783 by using Danish naturalist Otto Friedrich Müller. Diatoms are producers within the meals chain. A particular characteristic of diatom cells is that they're enclosed inside a mobile wall product of silica (hydrated silicon dioxide) known as a frustule. These frustules show a wide variety in shape, but are generally nearly bilaterally symmetrical, as a result the group call. The symmetry isn't always ideal on the grounds that one of the valves is barely larger than the alternative, permitting one valve to fit within the edge of the other. Fossil proof indicates that they originated for the duration of, or before, the early Jurassic duration. Only male gametes of centric diatoms are capable of motion by way of flagella. Diatom groups are a popular tool for monitoring environmental situations, past and gift, and are typically utilized in research of water high-quality.

Question 35. What Is Kerogen?

Answer :

Kerogen is a mixture of organic chemical compounds that make up a part of the organic depend in sedimentary rocks. It is insoluble in regular natural solvents due to the high molecular weight (upwards of 1,000 daltons or one thousand Da; 1Da= 1 atomic mass unit) of its factor compounds. The soluble element is called bitumen. When heated to the right temperatures within the Earth's crust, some forms of kerogen launch crude oil or natural gasoline, together called hydrocarbons (fossil fuels). When such kerogens are found in high attention in rocks such as shale, they shape possible source rocks. Shales wealthy in kerogens that have no longer been heated to a hotter temperature to launch their hydrocarbons can also form oil shale deposits.
