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: (edited) Actually it might be D
Explanation: ATP (adenosine triphosphate) makes food for your body, and we can only keep a small amount of ATP and glucose stored in our bodies at a time. When you run, your body is trying to create extra ATP. In order to do that, you need more oxygen intake, so you start breathing heavier and quicker.
The sugar in DNA is called deoxyribose sugar; while the one found in RNA is called ribose sugar and they are both pentose sugars with the only difference that DNA lacks one oxygen atom.
