Answer:
The results from this experiment conclude that all of the resulting bacteria contain the pUC18 plasmid without the human gene.
The method of genetic engineering might seem very easy but in actual it is a very difficult task and most of the time a person won;t get the expected results. The chances of a vector to actually take up a recombinant DNA are very less. Even after this, the chances of a recombinant plasmid to enter a bacterial cell by transformation are very few.
Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make <u>glucose</u>, <u>acetic acid</u>, <u>amino acids</u> and <u>lipids</u>.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.
Answer:
Avoid putting oils in water, and don't put trash in it either.
Answer:
<em>The correct option is C) It does not depend on insect pollination.</em>
Explanation:
Angiosperms can simply be described as the plants which produce flowers whereas gymnosperms are the plants which do not produce flowers.
Both, the gymnosperms and the angiosperms, are capable of producing seeds. However, the seeds of the angiosperms are enclosed in an ovary. The seeds of gymnosperms are not enclosed.
<u><em>One of the major differences between gymnosperms and angiosperms is that the angiosperms have to depend on animals for pollination. On the other hand, the seeds of gymnosperms are spread through the wind and are pollinated.</em></u>
