<u>Answer:</u>

<em>The biologists clarify these similarities as a homologous pair. This is based on the principle of convergent evolution.</em>

<u>Explanation:</u>

<em>Convergent evolution</em> is understood by the phenomenon of development of similar organs in different species in different period. Those<em> homologous pair </em>have same structure but can have different function in the different <em>species of organism. </em>

A given mass of oxygen at room temperature occupies a volume of 500. 0 ml at 1. 50 atm pressure. what pressure must be applied t
andreev551 [17]

5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

<h3>Given</h3>

Mass of oxygen at room temperature =500.0 ml

Volume of pressure = 50 atm pressure.

The gas to a volume = 150.0 ml

<h3>Explanation</h3>

The volume decreases by the factor = 500.0 mL / 150.0 mL

                                                             = 10 / 3

The pressure of the gas increased by a factor of 10/3 , which would make its final value equal to

P_{final} = \frac{10}{3} * 1.50 atm

          = 5.00 atm

So, 5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.
