Hope this helps! :)
Explanation:
Clams are adapted for burrowing in the mud and sand by having a short siphon (tube that intakes water) that allows them to expel mud and sand from their gils. They also have adapted by using their foot to dig down into the sand. The foot pushes down through the media and then the clam can pull it self down to the tip of their foot.

Recombinant DNA technology is a synonym for genetic engineering
Recombinant DNA technology (also called genetic engineering) is the combination of DNA molecules from two different species to create new genetic combinations that would not otherwise be found in the genome and that is of great importance to science and other fields. Recombinant DNA technology is mainly involved in the isolation, characterization, and alteration of DNA in organisms’ genome to create improved or novel organisms.
