Airida [17]

Answer:

<h2>5'-UCAAUGC-3'</h2>

Explanation:

According to base pairing rule of DNA and RNA, A is always pairs with T ( in case of DNA) or with U ( in case of RNA) with two hydrogen bonds(A=T), and C is always pairs with G in both DNA and RNA  with three hydrogen bonds ( C≡G).

As given here, one segment of RNA molecule containing sequence 5'-GCAUUGA-3', so as the rule, G always binds with C and so on, so the sequence of the binding segment would be 3'-CGUAACU-5'. it can be written as 5'-UCAAUGC-3'

The populations living on a rough, steep mountain would have a higher rate of speciation than this living in a large, open grass
exis [7]

The correct answer is option C, that is, have a wider range of environments.  

It has been known that geographic isolation is a general way for the initiation of the process of speciation, like the rise of mountains, rivers changing course, migration of organisms, continental drift, due to this what was once a steady population gets differentiated into two or more kinds of smaller populations.  

A mountain range, due to distinctions in temperature and precipitation as a result of different altitudes, can lead to a higher rate of speciation. Due to these differences, a single mountain range can exhibit an enormous array of biodiversity and climate zones.
