Paraphin [41]3 years ago
7 0

Answer:

The correct answer is option - microorganism.

Explanation:

The initial life form on earth was bacteria. These bacteria could live and survive in a toxic atmosphere at that time scale. Researchers and scientist believe that life in the earth were prokaryotes with no cell membrane and cell nucleus most probably bacteria.

All other organisms evolved later when there are enough oxygen and no toxicity in the environment.

Thus, the correct answer is option - microorganism.

The Phylogeny chart shows the evolution of camels. Camelus is the modern day cameo based on this chart which three statements ar
Nataly_w [17]

Answer:

  1. Modern camels are more related to Camelops than to Aepycamelus.
  2. Pliauchenia and Oxydactylus may share similar feautres.
  3. Procamelus and Stenomylous may share similar features.

Explanation:

The chart given explains how the camels are evolved between Eocene (33 myo) and Pleistocene.

  1. According to the chart, modern-day camels (Camelus) are a closer phylogenetic relative of Camelops because they are clustered together in the Pleistocene age section. However, Aepycamelus is last recorded in the Upper Miocene and later became extinct (or no record is found in Pliocene and Pleistocene).
  2. Pliauchenia and Oxydactylus have a single ancestor "Protylopus" which can be seen in the Eocene age. Although Protylopus were branched to two species in upper Miocene, it is not difficult to believe that they share many genetic similarities (features) in both lineages.
  3. Similarly, Procamelus and Stenomylous are the descendants of Poebrotherium and got apart at the end of the Oligocene, therefore, they will also share several features similar to each other.

Which value is being measured in the columns labeled fraction remaining and percentage remaining
ahrayia [7]

<u>Question</u>:

Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?

  1. years of decay
  2. quantity of energy
  3. number of stable atoms
  4. amount of material that has not decayed

<u>Answer</u>:

"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”

<u>Explanation</u>:

The table shown below having explains about the half life , the  amount of sample in both fraction and percentage. The first column named half life elapsed tells  us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.

The fraction remaining column gives the amount of sample that is left behind  after the half life particular number of half life has completed.  similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over \frac{1}{16} th of the sample remained. In percentage it is 6.25%
