Explanation:

1. The null hypothesis assumes no relationship or effect between variables in an experiment.
2. Biology is the scientific study of life and living organisms.
3. Erlenmeyer flasks have a conical shape that allows for easy swirling of liquids without spilling.
4. Research misconduct includes actions like falsifying data to get a desired result.
5. Robert Hooke coined the term "cell" after observing cork under a microscope.

Answer:

1. d. There is no relationship between the variables
2. d. Life and living organisms
3. b. They allow for swirling liquids without spilling
4. c. Adjusting or falsifying data to achieve a desired outcome
5. (Missing correct option as none of a - b are correct; it's Robert Hooke)
