Conjugation and transformation are both kinds of horizontal gene transfer that allow a cell to receive and recombine external DNA. Conjugation involves physical contact between two bacteria using a pilus, through which a copy of plasmid DNA is transferred from the donor (F+) cell to the recipient (F-) cell. Transformation, on the other hand, is simple uptake of naked DNA into a recipient cell from the environment. The DNA usually comes from the leftovers of a dead cell.
A mouse would be a fossil fuel first, since the fish would be in water it would have some source of living thing.
Answer:
The correct answer is "I would suggest her to change the Gram positive control from Bacillus subtilis to other bacteria".
Explanation:
Bacillus subtilis, and the species from the genre Bacillus, are known for losing the crystal violet coloration during Gram testing. It is likely that B. subtilis might look pink under the procedure for this reason. I would suggest to change her Gram positive control from B. subtilis to other bacteria. For instance, she could try with Staphylococcus aureus, a widely used bacteria as Gram positive control.
<span>During a decomposition reaction, a compund partitions into it's components. This is a type of a chemical reaction where a larger/more complex compund is broken down into simpler elements or compounds which were initially combined in a chemical reaction.This type of reaction often requires an energy source such as heat or light to break down the compound.</span>
