Answer:
The fourth plant that receives pure water is the control group.
Explanation:
The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, <em>the different concentrations of salty water that each plant receives</em>. The control group provides a reference point. It must be selected from the same population of the treatment groups. Both groups must be similar in every variable that might influence the results, <u>except for the study treatment.</u>
Answer:
The correct answer is- digestion, absorption, transport, elimination
Explanation:
The process of digestion starts from the mouth with the help of enzymes called salivary amylase present in our saliva. The food then passes through the esophagus to the stomach.
In the stomach, the food is broken down in small fragments by churning movement which mixes digestive enzymes and food to form chyme.
This chyme is passed to the small intestine where several enzymes from the liver and pancreas digest the food in smaller particles and absorb these particles in the blood. Therefore absorption takes place in the small intestine.
Then the solid waste material left behind after absorption is transported from small intestine to the large intestine and from large intestine waste is eliminated out of the body.
Therefore the correct order are: digestion → absorption→ transport→ elimination.
There are a few different names for Mitosis: Cell division and cellular division (these are the words that I can think of) I hope this helps.
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.
