Answer:
Gas exchange
Explanation:
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

Pros is that it helps water stay in one place and it also makes water more easily accessed for future use. The cons is animals can have less space to live and the overflow of water can occur which means flooding.
Answer:
Framshift mutation
Explanation:
The frame shift mutation is also known as reading frame shift or framing error mutation, during which an insertion or deletion occurs at a single position but it effects the sequence of whole gene in such a way that complete sequence is disturbed.
If we look at the sequence given in example:
Wild sequence: the big red fly had one eye
Mutant: the fbi gre dfl yha don eey
An insertion mutation occured at the start of sequence big, where f got inserted. We know that a 3 set of nucleotides called codon is transcribed and translated into single amino acid of protein. So when f got added it disturbed the frame and all the sequences of next codons got altered.
- big changed to fbi
- red changed to gre
- fly changed to dfl
- had changed to yha
In short the ehole protein will have wrong sequence of amino acid and it is worst type of mutation that badly effects an organism.
Hope it help!
