If thousands of glucose molecules were bonded together with equal numbers of sucrose molecules, the resulting substance could be described as a polysaccharide. They are <span>polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages.</span>

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
The movement of one of the transported substances up its concentration gradient
Answer:
The correct options are:
- <em>The population of birds with large beaks will increase on the island.</em>
- <em>The trait for large beaks will be passed on to future generations through natural selection.</em>
Explanation:
According to the theory of natural selection, those organisms tend to survive in an environment which are better adapted to live in an environment and which can better adapt to changes that occur in an environment.
The drought caused the small, soft seeds to decrease more in number as compared to the large, hard seeds. As a result, the birds having large beaks were better adapted to live in the environment as compared to the birds having small beaks. So the population of the large beak birds increased and they passed their characteristics to the future generations.
