Answer:
(A) -> (D) -> (C) -> (B)
Explanation:
First off, given that the problem requires us to explain how life on Earth may have arisen <u>from terrestrial origins</u>, we can discard sentence (E), as impacts from meteorites would count as extraterrestrial origins.
Then it's just a matter of describing the steps by which simple compounds turned into more and more complex structures, that would in turn lead to the origin of life.
Simple inorganic compounds (such as CO₂, or NH₃) were exposed to energy, because of that they formed simple organic molecules, like carbohydrates or amino acids.
These organic molecules, in turn, would self-assemble into more complex structures, such as proteins.
Lastly, there's the phenomenon of Compartmentalization, where large organic structures became enclosed within a membrane-like structure, separating them from the 'outside' medium and thus creating primitive cells.
Answer: They compare the number of mutations to determine how long ago species separated and evolved.

1. shut down the factory
This is a suggestion that will not be implemented simply due to the fact that the factory is likely to be bringing profits and meeting the requirements of a specific product or products. Shutting the factory down will mean great losses, which makes this suggestion non-feasible.
2. Move the factory out of the city
First, "moving" a factory is not as easy as it sounds. For a factory to be set up, many factors are considered such as the availability of raw materials and transport cost. Moreover, the emissions will still not be lessened if the factory is simply moved.
3. Increase the height of the factory's chimney
If these emissions are harming the nearby environment, this suggestion will help to reduce those effects. However, the negative effects will inevitably occur if there is a high level of emission of sulfur dioxide occurring, such as acid rain. Therefore, this does not solve the problem, only changes its nature.
Answer: Hydrogen-3 or tritium as it is commonly called, has a half life of 12.32 years. If you start with 20 grams of it, how much will remain after 25 years? Ending Amount = Beginning Amount / 2 (time / half-life) Ending Amount = 20 / 2 (25 / 12.32) Ending Amount = 20 / 2 (2.0292) Ending Amount = 20 / 4.0818. Ending Amount = 4.8997 grams

This is ur answer.....
<em>1</em><em>.</em><em> </em><em>Ruminant stomachs have four compartments, and monogastric stomachs have only one compartment. Ruminants are able to digest grasses and other fibrous feeds better than animals with monogastric systems can</em><em>.</em>
<em> </em><em> </em><em> </em>
<em>2</em><em>.</em><em> </em><em>The bacteria can digest fiber allowing the dairy cow to consume grass, forages, and fibrous by-product feeds that humans or monogastric animals cannot do effectively. The abomasum is the stomach compartment similar to the human stomach.</em>
