Thank you for posting your question here at brainly. <span>Plasmids can be used to incorporate a desired gene into something else which is lacking the gene. An example would be that you could take a plasmid from a bacteria which is resistant to an antibiotic and put it into a bacteria which is not resistant to the antibiotic. Therefore, the insertion of the plasmid would make the susceptible bacteria resistant.</span>
Conduction and convection are means of transferring heat, the important difference is the medium through which the heat travels. Conduction occurs when heat is transferred through solid objects, like a bar.
Answer:
C) Sound energy travelled as waves from one tuning fork to the other.
Explanation:
The air consists of particles. These particles transfer energy using waves.
You will need to complete a Punnett square to answer this. Let's say tongue rolling is R and non-rollers are r. The heterozygous roller would be Rr and the non-roller would be rr.
Rr x rr
That yields two offspring with Rr (rollers) and two rr (non-rollers). The ratio is 2:2 or 50%. See the attached image for the completed Punnett square.
