<span>A physical system is best characterized as a collection of MATTER THAT HAS DISTINCT BOUNDARIES.
</span><span>How does this phenomenon validate the Law of Conservation of Energy?
</span><span>The light energy travels through the water until it is reflected or absorbed.
</span><span>What conditions would most likely be present in this region?
Organisms growing on bare rock
</span><span>What is the best explanation based on these observations?
</span><span>Lobsters are adapting to cooler temperatures.
</span><span>- Ideal water temperature for lobster is around 53-64 degrees Fahrenheit. With the exceedingly warm waters (68 degrees Fahrenheit), lobsters are forced to move to the north where the temperature is ideal for their life cycles.</span>
Ecosystems experience change through human activity and natural events. This is because human activity can impact changes in nature, like climate for example. As a result, ecosystems change in response to the change in nature or natural events, which was caused by human activities. They are interrelated so to speak.
Answer:
C.
Explanation:
Every DNA nucleotide pair will consist of one pyrimidine and one purine. Due to the chemical structures of the different bases, adenine (A) will always bind with thymine (T) and guanine (G) will bind with cytosine (C). The same is true for RNA except that A always pairs with a close relative of thymine, uracil (U).
