Answer:
B. similar to the cells just treated with the dye - 0% dead
Explanation:
According to this question, an experiment was set up in which kidney cells were treated with a chemical for different amounts of time. Hence, the independent/manipulable variable is the CHEMICAL.
Based on the observation of the group of cells, a cell that has been damaged by the chemical will appear pink when treated with dye while a cell treated with only due but no chemical will not appear pink.
A NEGATIVE CONTROL is the group in an experiment that is not treated with the independent variable i.e. doesn't receive experimental treatment. Since the independent variable in this experiment is the CHEMICAL, the negative control will be the group that doesn't receive the chemical treatment. Hence, the negative control is similar to the cells just treated with the dye - 0% dead
Answer:
As the diagram is not given, hence let's generally describe the movement of molecules along the cell membrane.
Molecules can either pass through the cell without using energy through the process of passive transport. An example includes molecules of oxygen.
Molecules which are large and un-polar cannot move through the cell membrane easily. These molecules will require energy to move through the cell membrane. These molecules might move in with the help of the carrier or facilitated proteins. Examples include molecules of glucose.
Due to the definition of the central dogma, another way of putting it is that the central dogma follows the flow of information from DNA to protein.
Answer:
The traits were linked
Explanation:
Gregor Mendel often called the father of genetics was a priest as well as scientist. He conducted many science experiments and determined the law of independent assortment and segregation. He did however noticed that there were some traits seen in the parents that were passed to the offspring in the same combination. These were termed "linked-traits" and were the first indications that genes may be linked.
So it can be easily accesed. and also because if they didnt, it would be outdated with todays technology. hope this helps.
