Answer:
The bacteria with the mutation will survive.
Explanation:
In this population, if there is a group of bacteria of the same specie that mutate and this mutation is the expression of antibiotic resistance, this mean that the "mutant bacteria" are going to live spite the action of the drug.
Meanwhile the rest of the population is going to die because these group of living things are susceptible to the antibiotic, that means, they are going to die.
In the other hand, the "mutant" living things, by passing the time are going to reproduce and lead a new generation of bacteria resistant to the antibiotic.
Answer:
A cell wall, a broad central vacuole, and plastids such as chloroplasts are all present in plant cells. The cell wall is a dense layer that covers the cell and provides structural support and protection. It is located outside the cell membrane. The turgor pressure against the cell wall is maintained by the central vacuole.
Explanation:
The correct answer is A.
Oswald Avery applied several biochemical techniques to large cultures of bacteria in order to extract and purify the "transforming principle". Their experiments showed that most probably the "transforming principle" was DNA. One of the observations leading to this conclusion was that enzymes that degrade proteins or RNA (such ribonucleases) had no effect on the "transforming principle". On the contrary, enzymes degrading the DNA destroyed the extract's transforming capacity.
