Answer:
-Physical properties possessed by all stars:
- They are made of gases such as hydrogen and helium.
- They shine very brightly due to interaction of hydrogen and helium at appropriate pressure and temperature.
- They contain iron in their cores which monitors the fusion reaction.
- They make energy through fusion between the gases present in the stars which are hydrogen and helium.
- They are not spherical in shape hence this physical property is false in terms physical properties of the stars.
Hope this helps. If it does, please mark me brainliest.
Explanation:
Helium does not react with any other substances, thus the substance’s internal structure is never greatly affected and thus helium cannot have any chemical properties.
Archaebacteria move by using the form of a flagellum to propel a themselves.
