Aristotle developed the geocentric model that states the sun, moon, and stars seem to revolve around the Earth. Copernicus developed the heliocentric model that states the sun is at the center and other celestial bodies of the solar system orbit around it. The Sun-Earth-Moon System is based on the heliocentric model

Answer:

1. Kepler's third law relates the period of a ciosed orbit to its <u>major axis</u>.

2 The sun's <u>gravity</u> keeps planets in our solar system in orbit around the sun.

3. Comets are examples of bodies that complete parabolic or <u>hyperbolic</u> orbits.

4. The orbits of all the planets in the solar system are slightly elliptical with the exception of <u>pluto</u>.

5. Kepler's laws describe how objects move through space; <u>Newton's</u> laws describe why objects move in this way.

6. The geocentric and heliocentric models are models describing the universe. 'Geo' means earth, while 'helio' means sun.

The main difference between the two models is that the geocentric model describes earth as the centre of the universe; while the heliocentric model describes the sun as being the centre of the universe.

Explanation:

  • The geocentric model was proposed by a Greek philosopher called Aristotle who believed that the universe was perfect and finite. He stated that the sun, moon, the planets and stars all revolve around the earth.
  • The heliocentric model was developed by a Polish astronomer called Copernicus who argued that the sun, rather than the earth, was the centre of the universe, and all planets revolve around it.
  • Contradictory evidence in the motions of the planetary bodies led to the rejection of the geocentric model by another Greek called Galileo, who went on to support the heliocentric theory.
  • His view was highly controversial at the time, but it prevailed, and today we know the system as the Solar system.

How do the resurection of fern, crysts of brine shrimps and tardigrade survive with no water?
ehidna [41]
They survive without water by entering a special mode, otherwise called as shriveling. They can lose even 95% of water in their body and still live, even though they would look like dead plants, they would actually be alive. In the absence of water, tardigrades use a sugar called trehalose, which becomes their source of life until they find some water.

What is meant by transpiration is a necessaru evil?
3241004551 [841]
In plants, transpiration is a process which is inevitable but potentially harmful, because it can cause loss of water. Loss of water can lead to wilting and eventual death of the plant. Even a little stress can interfere with the plant's growth process. 

But, at the same time, transpiration is necessary because of a number of reasons - the transpiration stream aids the processes of mineral absorption, water absorption, energy exchange, helps provide the plant with optimum turgidity, it helps the exchange of gases and so on.
