Hypothesis: If the tablet is placed in warm water, then the tablet will dissolve faster because an increase in temperature speeds up the dissolving rate of some substances.
The correct answer is:
Plants close their stomata during times of intense heat or drought in order to prevent water loss and maintain homeostasis.
Explanation:
Guard cells tend to open stomata within the day when there are lots of day and close stomata at night when the sun is not present and photosynthesis is not happening. They will also close stomata if the air is dry or hot, which minimizes water waste indoors evaporation.
Chloroplasts are the organelles that contain the chlorophyll pigment, which is essential for the good-making process of photosynthesis.
