<span>The neutral nature of water changes due to mixing of various salts, bases, and acids, thus changing its pH. </span>
Answer:
CAAGGUCUC
Explanation:
In an RNA strand, the bases would be Thymine, Uracil, Guanine and Cytosine.
The difference in the bases between DNA and RNA is that in RNA the complementary base of thymine is uracil, but in DNA the complementary base of thymine is adenine.
<span>They consume food and they have much higher metabolism. That means that more waste products are produced. Plants can use much of the waste produced and it is in fact raw material. Animals don't normally produce their own chemicals from scratch like plants normally do so they can't just recycle the waste. They need to remove it. About the only waste plants need to get rid of is excess oxygen produced during the day. That is actually three reasons but recycling is related to plants not consuming but making their own chemicals from scratch. In a way it pretty much comes down to one main reason.</span>

Hey you! Here's your answer:
1) Scientists discovered ways to derive embryonic stem cells in 1981, more than 30 years ago.
2) Canadian Scientists Dr. James Till and Ernest McCulloch, who did pioneering studies in stem cell research, were the first to discover stem cells.
3) Thousands of experiments and studies have already been conducted on stem cells and research.
I Really Hope This Helped You! :)
Answer: d. All of the above
Explanation:
Evolution can be define as the change that occur in a particular species over a time. Such changes are because of natural selection of favorable traits responsible for the survival of the organisms under unfavorable conditions.
a. Increasing phenotypic complexity over time: Some of the phenotypic traits make the organism suitable for survival of the species. These traits are transferred to the members of the next generation. This process leads to the development of new species.
b. A change occurring in individuals as a result of selection: The evolution is a change that occur after the process of natural selection as the organism adapts according to the traits they exhibit.
c. Descent with change: The ancestors are the organisms which undergoes changes such changes are transferred to the new generation that is descents.
