Scientist usually use the process of relative dating to begin with, then chemical dating. They look at where the environment that they found the fossil to determine if it has always been that environment. ie i found fossils of marine life in a country town suggesting that the environment was previously a marine environment.
They study the rocks that we found the fossils to help determine a relative age. ie this came before that, but after them to give us an approximate age. they then study the fossil itself to classify it into groups to determine which branch of evolution it has come from. 
<span>Fossils can be found in rocks, bedding planes,(rock layers), trees (tree ring dating). mostly there are found in rocks or weathered rocks (sands, mud).</span>

Use the drop-down menus to complete each sentence.
Svetlanka [38]

Answer:

- <u>Eukaryotes</u> are organisms that contain more than one cell with membrane-bound organelles and a nucleus.

- Organisms that contain only one cell and do not contain a nucleus or membrane-bound organelles are known as <u>prokaryotes</u>.

Explanation:

According to their structural and functional complexity, organisms can be classified into eukaryotes and prokaryotes.

  1. <em><u>Eukaryotic organisms</u></em><em> are formed by cells that have a true nucleus -where DNA is located- and specialized structures called organelles, with a system of endomembranes that compartmentalize the intracellular space. These organisms are usually pluricellular, given the ability of eukaryotic cells to group together to form tissues. </em>
  2. <em><u>Prokaryotic organisms</u></em><em> are single cells, lacking a nucleus - genetic material is scattered in the cytoplasm - and do not possess organelles.  The prokaryotic cells that form these organisms are incapable of binding together, so they do not form tissues.</em>

Some unicellular organisms are prokaryotic cells, like some parasitic microorganisms, such as amoebas.

Why consumer in a food chain can’t get access to all energy in food chain?
tigry1 [53]

Answer:

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. A food chain can usually sustain no more than six energy transfers before all the energy is used up
