Answer:
<h2> 1, 4, and 5</h2><h2>1. horizontal gene transfer,4. transformation and 5. genetic recombination.</h2>
Explanation:
In Fred Griffith's experiments, harmless R (rough) strain pneumococcus became lethal S (smooth) strain pneumococcus as the result gene transfer from smooth to rough strain. Gene transfer is the process through which genes are transferred from one cell or organism to other, and after transfer, genetic recombination occurs.

First class lever
Third class lever
Second class lever
Second class lever
