Answer:
Hypothesis: IF Aloe vera is applied, THEN the number of regenerated planaria will increase
Independent variable: The different amounts of Aloe vera applied
Dependent variable: Number of regenerated planaria
Control group: The parts of planaria that received 0% of Aloe vera
Conclusion: The Hypothesis should be rejected
Explanation:
Hypothesis in an experiment is a testable explanation to an observed problem. It aims at proferring a possible solution/answer to a question. In this experiment, the hypothesis will be: IF Aloe vera is applied, THEN the number of regenerated planaria will increase
The independent variable refers to the variable being manipulated or changed in the experiment while the dependent variable is the variable that responds to the changes made to the independent variable. The dependent variable is the measured variable. In this experiment, the independent variable is THE DIFFERENT AMOUNTS OF ALOE VERA APPLIED while the dependent variable is THE NUMBER OF REGENERATED PLANARIA.
The control group of an experiment is the group that differs from the experimental group by not receiving the experimental treatment (independent variable). In this experiment, the control is the PART OF PLANARIA THAT RECEIVES 0% OF ALOE VERA.
Based on the outcome of the experiment, it can be seen that there was an initial increase in number of regenerated planaria but the number later declined, hence, the hypothesis given will be REJECTED as it doesn't explain the declination.
Answer: Option B) Yes, the solution is hypotonic, causing the cell to burst.
Explanation:
Because a hypotonic solution is of lower concentration to its surrounding, a cell placed in such solution absorbs the content of the solution, swells and then burst due to the uncontrolled inflow of the solution through its cell membrane.
Thus, the answer is Yes, the solution is hypotonic and cause the cell to burst.
Answer:- Calvin cycle
Explanation:-
Photosynthesis occurs in two parts:
1. Light dependent reaction which requires sunlight. In this reaction the energy from sunlight gets absorbed by the chlorophyll and is then converted into chemical energy in the form of NADPH and ATP.
2. Light independent reaction which is also known as the calvincycle takes place to provide energy to form carbohydrates using the energized electrons that were obtained from the light dependent reactions. Since, they do not require light for their reaction they can also occur during the night.
brainliest if you mind thanks
The answer is 1). Two Tt parent can produce T and t for 50% separately. So for the result, TT has the probability of 50%*50%=25%. The same for tt. And Tt is 1-0.25-0.25=50%.
The answer would be bronchitis as it has to do the bronchial tubes
Hope this helps :)
