Naily [24]

Answer:

Option B, Most tornadoes have funnels taller than 105 m

Explanation:

As per the UCAR center for science,  formation of tornadoes is not a season specific event. It can form at any point of time in a year but the majority of tornadoes have occurred in spring and summer months. These tornadoes are also accompanied by thunderstorms in the month of may and june.

As per the national geographic channel estimate , the maximum speed of wind of a tornado noted till date is 110 kilometer per hour. Thus,  saying that speed of  most of the tornado is greater than 105 kph is acceptable  to some extent.

Also , tornado occurs usually during the hottest part of the day when the air next to ground gets heated.

Hence, option B is incorrect

Colt1911 [192]

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.
