Answer:
There is no control group and variables were not addressed.
Explanation:
In the context, it is given that there is a dumping ground in a small town called Love Canal and harmful chemical waste of industries are dumped there. Lately, it is noticed that there were traces of the toxic substances on the walls of the schools and the hospitals. The hospitals also noticed that during the period of 1970 to 1980, there were increase in the number of the birth defects in the area. The people of the Love Canal has genetic abnormalities and the chemical waste is responsible for it.
Thus it can be concluded that there is a no such any control group in this case. The confounding variables like the comorbidities as well as the family history of the genetic defects were not addressed.
Answer: C.) They need the host cell to replicate
Explanation:
Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
If a higher concentration of salt is placed outside of the cell membrane, the water will leave the cell to bond with it. The loss of water from this movement causes plant cells to shrink and wilt.
Answer:
YES!!!!
Explanation:
It's correct because this is one of 10 steps invloving the bacteria state The process in natural selection has resulted in this evolution of such resistance dut to the idea of getting a mutation (adaptation) in which It helped the bacteria to be able to survive better than others kinds of bacteria. So others may die off, but this bacteria copies itself off, and now the whole species may be resistant to the antibiotic, causing a difficulty in using them to trea
Answer:
The cell will shrink due to osmosis.
Explanation:
As in given question the salt concentration are much more inside the cell, than outside. In order to maintain equilibrium. the water inside the cell will start flowing outside in order to maintain equilibrium, causing shrinkage of cell. The ability of a cell to divide or function will reduce because of water loss. This phenomenon is seen in case of hypertonic solution. Water will start diffusing from the higher concentration to the lower concentration.
