Answer:
Trophic Cascade
Explanation:
Trophic cascade is when the ecosystem experiences a level of a certain species being reduced or removed.
If the results show that 21% of the nucleotides contain adenine, then the cytosine fraction in vivo is 29% and the thymine fraction is also 21% (options A and C).
<h3>Define double helix model of DNA?</h3>
- DNA is a double helix molecule made up of two long strands of nucleotides.
- There are four types of nucleotides in DNA, each containing a different nitrogenous base: adenine, guanine, thymine, cytosine.
- Adenine always pairs with thymine and guanine pairs with cytosine, according to the base-pairing rules.
- As a result, the percentage of adenine equals the percentage of thymine, and the remaining percentage equals guanine + cytosine (29 + 29 = 58 >> 58 + 21 + 21 = 100).
- Therefore, if the results show that 21% of the nucleotides contain adenine, then the percentage of cytosine in vivo is 29% and the percentage of thymine is also 21%

The complete question is as follows:
The DNA content for an organism is analyzed. The results showed that 21% of the nucleotides contained the nitrogenous base adenine. What else can be inferred based on this data? Select all that apply
A) The percentage of cytosine is 29%.
B) The percentage of adenine is 21% for all organisms.
C) The percentage of thymine in the organism is also 21%.
D) The percentage of guanine in the organism is also 21%.
E) The percentage for cytosine in the organism is also 21%.
Answer:
Write a lab report that summarizes his experiment
Hi,
By studying fossils, scientists can learn how life has changed over time, how earth's surface has changed and what past environments were like. Fossils form when living things die and are buried by sediment; they are usually found in Sedimentary rock. Only the hard parts of organisms generally leave fossils because the soft parts generally decay too quickly to fossilize. In case you didn't know, there are two types of fossils; rock fossils and preserved fossils.
Option c) is the correct option above.
<span>c) Fossils give information about the time period in which organisms lived in the past.
