D.) none of the above is human induced cause of extinction
Guessing you mean "impulse".
It means to have a sudden strong desire to do something or a small amount of energy that moves from one area to another.
Hope this helps.
Answer and Explanation
Mendel selected a group of dwarf plants and sel pollinated them by dusting mature pollen grains onto them. He then collected the resulting seeds and planted them and noticed these seeds germinated and grew into dwarf plants only.
He also selected tall plants and self-pollinated them. the resulting seeds he observed that they grew into a micture of tall and dwarf plants. He took the seeds of tall plants only and repeated the experiments for many generations until he obtained only tall plants.
He then crossed cross-pollinated purebreeds tall garden pea with pure breed variety. He planted the seeds and observed the offsprings were all tall plants. He crossed two of these tall offsprinf from the F1 and planted the resulting seeds. the second filial generation consisted of a mixture of tall and dwarf plants.
He counted these plants and noted that the ratio of tall to dwarf was about 3:1. From this, he postulated that there are now laws governing inheritance.The law of independent assortment and law of segregation.
The type of bond formed between carbon and hydrogen is NON POLAR COVALENT BOND.
Covalent bond involves sharing of atoms between two elements; each element will donate electrons which will be equally shared by the elements involved. In the case of carbon and hydrogen, carbon has four electrons in its outermost shell, therefore it will form a covalent bond with four atoms of hydrogen each of which will donate one electron.
The OECD found that the responsiveness of housing supply to demand in the UK was the weakest among developed countries, due in large part to green belt policies. The green belt concept was first introduced for London in 1938 before the 1947 Town and Country Planning Act enabled local authorities to designate the status themselves. The policy was introduced to contain urban sprawl following huge post-war housing developments, and expanded greatly between 1951 and 1964. Since 1979, the green belt has doubled to cover 13 per cent of land in England (while only 2.3 per cent is covered by buildings).
