The condition is which characteristics of atmosphere III is nitrogen-rich and oxygen-poor. Nitrogen-rich is one of the condition in which the atmosphere III characterizes. The other is oxygen-poor, is one of the condition characterizes atmosphere III. Nitrogen-rich material mostly called green because they are greenish in color. Oxygen-poor means the blood enters the RA or Right atrium or the upper chamber of the heart.
Answer:
Decomposers recycle essential nutrients back into an ecosystem
Explanation:
An ecosystem works thanks to the constant transformation of energy. The role of the decomposers will be to transform energy into something useful in the ecosystem. For example, The bacteria which will rotten the apples that fall from a tree onto the ground are recycling or making available this energy for other organisms to use it. As part of this example, the essential nutrients of the apples will be available to be reabsorved by the roots of the apple tree thanks to the transformation of energy done by the bacteria in the apples.
Answer:
True
Explanation:
The Devonian Period comprises the years between 416 million and 354 million and is subdivided by periods: Lower (the oldest), Middle and Upper (the most recent).
During this period, the main transformations occurred in the flora, with the exponential growth of small terrestrial plants through the development of spores. With this process, plants will become more similar with modern plants. During this period the plants were able to fertilize themselves with the seeds and reach the height of trees. They formed the first forests to be recorded, with the appearance of licopodia, ferns and progimosperms.
Answer:
To achieve precipitation of the DNA.
Explanation:
Isopropyl alcohol makes the DNA sediment. The DNA, once out of the solution, becomes visible, as it clumps.
The result of adding isopropyl alcohol is the precipitation or sedimentation of DNA when DNA becomes like a visible thread with the help of alcohol and salt. The precipitation of DNA is important because it removes the dirt from DNA.
