Radio telescope picks up the radio spectrum of electromagnetic waves from celestial bodies (just like telescopes like the Hubble pick up visible light – only that radio waves are invisible to our eyes). They are therefore used to detect objects in space that produces radio waves. Examples are quasars and pulsars. Radio telescopes also enable astronomers to be whats beyond gas and dust in space that blocks out most of the visible light spectrum.
Answer :
Plants take in carbon dioxide from the atmosphere, water from the soil and light energy from Sun.
Photosynthesis occurs.
Oxygen and energy are produced.
There are 21% of oxygen in the atmosphere.
Answer:
Spores.
Explanation:
Sporulation is a type of asexual reproduction which occurs in organisms such as fungi, bacteria. In sporulation, specialized cells transformed into a hard resistant resting structure to overcome unfavourable condition. On the return of favourable conditions spores germinate to form new offspring. Sporulation is very common in fungi.
Scientists believe that the Earth's early atmosphere lacked oxygen because photosynthetic organisms did not yet exist. Hope this helps and have a great day!
