They correspond to Alanine
<span>What a fascinating question! Just out of college, on my first job,
I was called to the delivery room to assist the obstetrician in
collecting a blood sample from the not-yet born fetus? scalp. I was
nearly immobilized at the sight of the impending birth. Ever since
that night, I have gotten goosebumps when witnessing a birth. It is
certainly an amazing event, and pondering the entire journey from
conception to birth is marvelous!
Some of the material I have found is published by religious, political
and anti-abotion sites. Neither Google Answers nor I endorse any of
these sites. Such web pages were cited here for conception and
gestation information, and not because of ideology.</span>
Answer:
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).
Explanation:
The correct answer is - nitrogen and phosphorus.
The nitrogen and the phosphorus are the two substances that cause most of the eutrophication. It is good for the organisms that live in the water when these two substances are available as they are very important nutrients, but if the optimal amount is surpassed than it can be devastating. When there's high quantities of nitrogen and phosphorus in the water it makes it much more rich in nutrients that it should be. That kind of situation is the best for the algae, which start growing all over the place, quickly covering the water and becoming the dominant life form. As that happens, the organisms that use photosynthesis will die out because the Sun will be blocked, and the algae will also contribute to a big reduction of the oxygen in the water too. The end result being totally destroyed ecosystem that has been overtaken by algae.
