Answer:
a. What is the effect of cold weather on the rate of photosynthesis in Geranium plants with adequate sunlight and carbon dioxide?
b. If the temperature drops below a certain threshold, the rate of photosynthesis in Geranium plants will not increase, despite the presence of adequate sunlight and carbon dioxide.
c. The independent variable is the temperature, while the dependent variable is the rate of photosynthesis in Geranium plants.
Step-by-step explanation:
a. The research question is asking about the relationship between temperature and the rate of photosynthesis in Geranium plants. It is a specific and focused question that the experiment aims to answer.
b. The hypothesis is a proposed explanation for the phenomenon observed in the experiment. In this case, the hypothesis suggests that if the temperature is low, then the rate of photosynthesis in Geranium plants will not increase, despite adequate sunlight and carbon dioxide.
c. The independent variable is the temperature because it is the variable that is being manipulated or changed in the experiment. The dependent variable is the rate of photosynthesis because it is the variable that is being measured or observed and is dependent on the changes in the independent variable (temperature).
