Answer:
C) Stay the same
Explanation:
Bacteria have rigid cell walls around their cell membrane. When placed in a hypotonic solution, water enters into the bacterial cell by the process of endosmosis. However, the rigid cell wall resists the increase in the volume of the cytoplasm.
The entry of water into the bacterial cell results in the build-up of turgor pressure inside the cell. Build up enough pressure inside the cell prevents the entry of water into the cell. So, when placed in a hypotonic solution, bacterial cells stay the same due to the presence of rigid cell walls.

The physical appearance of the biochemical characteristic of an organism as result of the interaction of phenotype; some mutation has the positive effect on the organism in which they occur.
<u>Explanation:</u>
They are called beneficial mutation. Phenotype of the organism lead to new development of proteins which help the organisms to adopt their own environment. Beneficial mutation are essential for evaluation to occur.
Phenotype stretch the DNA without any function; the mutations occur in a protein coating region, but it end up the process by not affecting sequence of the protein.
Example of phenotype are:
Observable characteristics including behaviour, biochemical properties; the phenotype benefits such as HIV resistance, lactose resistance.
Answer:
Interesting, I thought you only had two days to live and was on breathing tube?
The correct answer is that they both contain the elements silicon and oxygen.
Carlos is conducting a controlled experiment. A controlled experiment is a scientific test where only one variable is changed and there is a group of subjects (named the control group) that is not receiving the factor that is being tested. The group of subjects receiving a treatment or the factor which is being tested is called the experimental group. The variable which is different between the control and the experimental group is the independent variable. The dependent variable depends on the independent variable and represents the response that we observe as an outcome of our experiment.
