In sedimentary rock the oldest fossils would be expected to be found
eduard

Answer:

At the bottom of the sequence

Explanation:

According to the "principle of superposition of strata", the oldest rocks are formed at the bottom of sedimentary rock sequences.

The oldest rock layer would contain the the oldest fossil. Weathering, erosion, transportation and deposition would bring all sediments which includes rock materials and remains of living organisms to the basin where they would be lithified to form sedimentary rocks. This makes the oldest fossil to be at the bottom of the sequence. As time progresses, the fossil sequence would continue to accumulate and young upwards as the strata becomes relatively younger. Also, we know that fossils succeed one another in a definite manner.

This why relative dating of rocks can be possible.

Which of the following pairs of protists and their ecological roles are correctly matched?
melisa1 [442]

Answer:

The correct pair is A: "apicomplexans—parasites of animals"

Explanation:

  • Euglenophyta is a group of unicellular, eukaryotic organisms. They are small, free-living forms, or parasites that present different feeding mechanisms and behaviors, such as heterotrophy, autotrophy, or mixotrophy.
  • Dinoflagellates are unicellular, flagellated, free-living protists that might form colonies. Most of them are autotrophic organisms but some of them are heterotrophic, or mixotrophic. In these last cases, dinoflagellates can feed on other dinoflagellates, protozoans, or diatoms. They can also be parasites.
  • Entamoebas are endoparasitic organisms with no mitochondria as an adaptation of living in environments with low oxygen concentration.
  • Apicomplexa is a unicellular, protist group. They have medical and economic importance as they are<u> animals</u> and human parasites. They have an apical complex that helps them to fixate to the host cell and release a substance that provokes an invagination in the host membrane. This invagination allows the parasite to get into the host cell.
