Liquid 1 and 4, because they have the same melting point and density.
Tamilnadu, Punjab, are the most famous places in India where cattle farming are done.
Organic compound is generally any chemical compound that contains carbon. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. Study of the properties and synthesis of organic compounds is the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonates and cyanides), along with a handful of other exceptions (e.g., carbon dioxide), are not classified as organic compounds and are considered inorganic. No consensus exists among chemists on precisely which carbon-containing compounds are excluded, making the definition of an organic compound elusive.[1]Although organic compounds only make up a small percentage of the Earth's crust, they are of central importance because all known life is based on organic compounds. Most synthetically produced organic compounds are ultimately derived from petrochemicalsconsisting mainly of hydrocarbons.
Natural selection would cause speciation because the new advantageous traits introduced in the population would help species survive and adapt to the new environment they are in because of isolation. The ability to make best from available leads to speciation in isolation.
Explanation:
Natural selection is a an important element of evolution. The change in traits which are beneficial and heritable are transferred from one generation to other. These traits come from random mutations.
Speciation is a process in which an existing population diverge in to two distinct population or species due to geographic barrier or without it also. The speciation occurs when species from one group become reproductive isolated.
When a group of species become isolated on an island or some other geographic boundary.
The increase or introduction of new beneficial genes in a population is caused by natural selection process. The populations manage to survive and adapt the new environment and become a new species if left isolated.
