What three types of evidence allows us to determine whether organisms shared a common ancestor?

Biology

Anika [276]3 years ago

The evidence of common ancestry is based on study of three   parameters;   fossils record, homologies of various organisms, and study of biogeography. Fossils record   determines the similarity and differences of bones as well as shells of different organisms   over a given period of time.   On the other hand, studying of homologies involves assessment of mitochondrial DNA and other proteins with an aim of finding similarity from one organism to another.  Finally, Biogeography is the assessment of how continental drift might have separated organisms which had got common ancestry and they were living together.

Marrrta [24]

Answer:

Phenotypic changes:

When Rhodobacter is cultured in total darkness for multiple generations, the ability to produce it's own photopigment reduces with time with little or no ability to undergo its own photosynthesis due to absence of enzymes or pigment for photosynthesis.

It becomes expensive for the Rhodobacter to undergo photosynthesis. This allows mutants that can grow in the dark to take over from the culture grown in the dark.

Evolutionary processes:

It's natural selection that allows the fittest organism to survive. As in the case of the mutants

morpeh [17]

It is mostly likely the cell membrane.

The cell membrane is a structure of a cell composed of double layer of lipids and proteins. It surrounds a cell and separates the cytoplasm from its surrounding environment. The cell membrane is selectively permeable (semi-permeable), which means that it only lets certain molecules enter and exit. It can also control the amount of some substances that go into or out of the cell.

Yuki888 [10]
<h2>A<em>denosine triphosphate</em></h2>

Explanation:

  • <em>ATP, or adenosine triphosphate, is synthetic vitality the cell can utilize.</em>
  • The particle gives vitality to your cells to perform work, for example, moving your muscles as you stroll down the street.<em>When ATP is separated into ADP (adenosine diphosphate) and inorganic phosphate, vitality is discharged.  </em>
  • ATP is converted into ADP which can be recycled back into ATP Is Converted into A waste product that The cell excretes ATP Is broken down into its individual parts and would need to be re-made Through metabolism to be used again.  
  • At the point when one phosphate bunch is expelled by breaking a <em>phosphoanhydride bond in a procedure called hydrolysis,</em> <em>vitality is discharged, and ATP is changed over to adenosine diphosphate (ADP).  </em>
  • <em>ATP works as the vitality cash for cells.</em> It permits the cell to store vitality quickly and transport it inside the cell to help endergonic concoction reactions.
  • As ATP is utilized for vitality, a phosphate gathering or two are withdrawn, and either ADP or AMP is created.
