The scientist asks a new question because the results of the first investigation lead to new scientific questions that need to be tested. After asking a new question (a question that is based on observations and that is testable) the scientist will form a hypothesis that needs to be tested.
Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.

Explanation:
Channel proteins use passive transport, that is, they do not require energy such as ATP for transporting molecules.
I have never heard of the four phases of research, but I know that the scientific method can be summarized in four steps.
1. Observe something in nature.
2. Make a hypothesis (prediction) based on that observation.
3. Design and undergo and experiment to test the validity of your hypothesis.
4. Draw a conclusion about your hypothesis based on the results of your experiment.
Answer:
Permanent tissue consist of more than one time of cell and all are differeniated but meristemic tissue consist of undiffereniated cells.
Meristemic cells are simple but permanent cells are complex in nature.
Meristamic cell responsible for primary and secondary growth and permanent tissue helps in overall growth of plants
