Answer:
A) Formulate question,conduct research,propose hypothesis,test hypothesis
Explanation:
The scientific method is pertinent to the success of a scientific experiment. The scientific method is a sequential steps of processes involved in an experimentation. The correct order of steps that determines the process when following the scientific method are:
1) Formulate question: Asking a question about what has been previously observed is the key to starting a scientific method.
2) Conduct research: Research is done based on a previous observation that has been made by in order to gather necessary information.
3) Propose hypothesis: A hypothesis is a predictive statement or explanation to an asked question about the experiment that can be tested. It usually goes in an IF, THEN format.
4) Test hypothesis: As stated in the previous step, a hypothesis must be testable, which is done by conducting an experiment. The outcome of the experiment proves or disproves the hypothesis.

Answer:
B) cytoplasmic streaming in hyphae
Explanation:
Fungal mycelium refers to the branched vegetative structure of the fungi which is formed by the growth of the hyphae. The hyphae contain three zones of growth: the apical, subapical and zone of vacuolation.
The hyphae grow in the apical region which forms a branched structure in which the cytoplasm continuously moves between the hyphae at the point of fusion towards the growing tip. This movement of the cytoplasm towards the growing tip is known as "cytoplasmic streaming".
This streaming of cytoplasm is responsible for the formation of a zone of vacuolation and the mycelium is formed.
Thus, Option-B is the correct answer.
The growing tip eventually gives rise to a branch. This is the beginning of the branched mycelium. Growing tips that come in contact with neighbouring hyphae often fuse with them to form a hyphal net. In such a vigorously growing system, the cytoplasm is in constant motion, streaming toward the growing tips. Eventually, the older hyphae become highly vacuolated and may be stripped of most of their cytoplasm.
