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:b) small stangnant pools do not provide enough water
Explanation:
African lungfish is obligate and fresh water habitat organism.
It aestivates between raining season During this peroid it produces UREA which is non toxic and stores iin the body to be excreted into water on the return of wet seasons.
Therefore, if it produces Ammonia, during Aestivation;ammonia is posinious and this kills the lungfish during aestivation of no water and oxygen supply.
It has changed in many ways. We went from saying just short, simple, sounds to longer, more precise sounds. Also, We have made actual words with syllables.
