Answer:

Yes,  in its atmosphere(21% oxygen) humans can walk on this planet without the aid of a space suit

Explanation:

The atmosphere of the earth has a percentage of 20.946% similar to the planet x with 21% oxygen.

Most living forms depend on the air: oxygen is necessary for the breathing of human beings. In the first 100Km the oxygen composition in the atmosphere remains stable.

Humans are very sensitive to oxygen levels, the magnitude of the oxygen deficit can lead to death but 215 is a  bearable percentage.

Which of the following shows an unsaturated fatty Acid? Out of those two
SVETLANKA909090 [29]

Answer:

None of these two

Explanation:

An unsaturated fatty acid must contain a double bond in the poly carbon chain other than the double bond in the functional group. In these two, images there exists a double bond in the carboxylic group i.e –COOH.  

Since none of them have double bond in long poly carbon chain, therefore these two fatty acids cannot  be considered as unsaturated fatty acid.
