Answer:
The color of the birdfeeders
Explanation:
Independent variable is the variable in the experiment that is changed, so the only thing changed in this experiment is the colors of the bird feeders
Answer:
It will eventually become less bright and cooler.
Explanation:
Astronomers estimate that the Sun's luminosity will increase by about 6% every billion years. This increase might seem slight, but it will render Earth inhospitable to life in about 1.1 billion years. The planet will be too hot to support life.
The Sun is a weakly variable star, and its actual luminosity therefore fluctuates. The major fluctuation is the eleven-year solar cycle (sunspot cycle) that causes a quasi-periodic variation of about ±0.1%. Other variations over the last 200–300 years are thought to be much smaller than this.
Answer:
the chemical equation for photosynthesis is 6CO2 + 6H2O → C6H12O6 + 6O2
Explanation:
reactents-Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
