Edwin Hubble used the Doppler effect to determine that the universe is expanding. After years of scientific research and observation of different celestial bodies through a telescope, Hubble found that the light from distant galaxies was shifted towards the red end of the spectrum. This red shift indicates that stars are moving away from us and from each other. This phenomenon is called the 'expansion of the universe', also known as the big band theory.

enyata [817]

Earth's tilt on its axis affects the way heat is distributed on Earth's surface.

A note on Diversity among protoctista (10 to 12 lines)​
asambeis [7]

Answer:

Protists are a diverse collection of organisms. While exceptions exist, they are primarily microscopic and unicellular, or made up of a single cell. The cells of protists are highly organized with a nucleus and specialized cellular machinery called organelles.

If an organism does not belong any particular kingdom, it goes into kingdom Protista. ... This miscellanous grouping causes the organisms in the kingdom to be very different from each other.
