Answer:
Changes in the composition of the atmosphere
Explanation:
Although this answer is very vague and generalized, it is the correct answer.
The increase in greenhouse gas emissions in the atmosphere from modern manufacturing and engineering has increase carbon dioxide and methane concentrations in the upper atmosphere. These gasses have a chemical composition that allows the absorption and release of longwave radiation back to the Earth's surface slowly increasing the global average temperature.
Mutations result from an error in DNA replication, should it be from an alien source (like radiation) or simply a mistake in replication.
Migration of organisms to a new population would alter the DNA by adding new genes, but it would not mutate them.
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:
218.75 grams of protein.
Explanation:
If 2500 protein is consumed and its 35% energy is provided by protein then:
2500÷35×100 =875 kcal would be provided by protein.
As one gram of protein provide 4 kcal of energy:
875÷4 = 218.75 grams of potein would be consumed.
<em>Remeber the calories and kcal for food is same.</em>
Yes it is C but for future reference, both A and B are referring to solids, and D is referring to a gas, hope this is helpful later!
