The right answer is A.Transcription uses uracil.
The genes carried by the DNA will be encoded in another form: messenger RNA, during a process called "transcription".
The DNA and RNA molecules are chemically very close, but the second has an extra oxygen (in red on the right of the letters) on the sugars (riboses) that make up its nucleotides (the DNA actually contains deoxyribose). In addition, the thymine (T) of DNA is replaced by uracil (U) in RNA.
Answer:
C: competitive exclusion
Explanation:
<em>The competitive exclusion principle states that organisms living in the same community while competing for the same resources cannot coexist at a constant population rate. </em>
Once some of the species within the community get a slight competitive edge over other species, they become dominant and this might lead to the extinction of the weaker species in the long run.
<u>In the experimental plot, the removal of sea stars provided mussel and barnacle with a competitive advantage over other species within the community (sea stars are predators of mussels and barnacles). This led to the dominance of mussel and barnacle and the eventual extinction of other species within the experimental plot as compared to the control plot.</u>
The correct answer is C.
Answer:
There will be few if any complications.
Explanation:
Just took the unit test review
All of these components are reservoirs of carbon. The cycle is usually discussed as four main reservoirs of carbon interconnected by pathways of exchange. The reservoirs are the atmosphere, terrestrial biosphere (usually includes freshwater systems), oceans, and sediments (includes fossil fuels).
