1 ) Dark matter affected the development of structures in the early universe by : ( A ) It seeded the development of galaxies

2 ) The scientific understanding of the composition of the universe has changed by ; ( A  and  B )

  • The percentage of dark matter has shrunk in scientists' estimates since the 1980s ( A ).
  • The percentage of unknown material has grown in scientists' estimates since the 1970 ( B ).

3) The evidence of the existence of dark energy is ; ( B ) Supernovae that are moving away at an accelerating rate.

Dark matter is a form of account assumed to be accountable for about 85% of the overall matter found on the universe. Dark matter seeded the development of the galaxies.

The existence of supernovae proves the existence of the effect of dark matter in the universe. meanwhile the scientific understanding of the composition of the universe has changed over time with scientists estimating the shrinking and growth of dark and unknown materials in the galaxy.

Hence we can conclude that the answers to your questions are as listed above numerically
