Question options:
1. developing a hypothesis to explain collected data
2. proving a theory and writing a new scientific law
3. collecting data through observation and measurement
4. observing and experimenting to test a hypothesis
Answer:
2. proving a theory and writing a new scientific law
Explanation:
Providing a theory and write a new scientific law is not a step of scientific investigation. To prove a law a theory, its take many years of research.
There are steps of scientific investigations below,
1. Make an Observation.
2. Form a Question.
3. Form a Hypothesis.
4. Conduct an Experiment.
5. Analyze the Data and
6. Draw a Conclusion.
These step of scientific investigation does not include to write a theory and scientific law.
Answer: a. Stomata open at Night
Explanation:
As a tactic to minimize photorespiration in warm regions, many water-storing plants such as cacti and pineapples modified its method of carbon fixation. This process is called Crassulacean Acid Metabolism (CAM), following the plant family Crassulaceae, in which it was first identified. In these plants, the stomata (singular, stoma), specialized openings in the leaves of all plants through which CO2 enters and water vapor is lost, open during the night and close during the day. This model of stomatal opening and closing is the opposite of that in most plants.
Answer:
Tracheids and vessels are two water conducting hollow tubes present in the vascular tissue called is xylem. Xylem in a plant is responsible for transporting water from the roots to other parts of the plant.
Answer:
Purpose- "the reason why something is done or used"
Research- An open access, peer reviewed Journal. Information about a topic that is gained by investigating prevous information gathered by someone else. systematic investigation. A systematic way of gathering data and harnessing curiosity.
Avoiding Bias- Avoiding Bias means to write info with curiosity and with research, not using personal opinion or preferance to write info.
Hypothesis- May be described as an educated guess based on research to describe and/or to explain the effect of a certain cause. Usually written in If....Then.... (A specific testable Prediction describing what you expect to happen in a certain circumstance)
Experiment-An emperical Procedure using scientific method to test and explain a certain circumstance.
Also, A trial or test, carried out under controlled conditions, to discover something unkown, to verify a hypothesis.
Independent Variable- The Variable that is changed during an experiment.
Dependent Variable- The Variable that you measure in response that is affected by the changes made.
Control- The Control variable is the Variable that remains Constant and does not change.
Analysis- The careful study of the data obtained from the experiment.
Conclusion-Short paragraph that discusses the overall results from the data obtained by the experiment and explains whether the hypothesis was right or wrong.
