When an ecosystem has a scarce nutrient, that is when there is a nutrient limitation.
So the answer is C. <span>Nitrogen is typically the limiting nutrient in freshwater environments.
This is because Nitrogen is the "scarce" nutrient </span>
Answer:
The sequence of the complementary strand of mRNA is AUCAUCAUC
Explanation: There are four bases in DNA: Adenine A, Thymine T, Guanine G, and Cytosine C while the bases found in RNA are Adenine A, Uracil U, Guanine G, and Cytosine C. In DNA base pairing, Adenine pairs with Thymine while in RNA base pairing, Adenine pairs with Uracil while Guanine pairs with Cytosine.
Answer: E. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Explanation:
The Hershey-Chase experiment, is an experiment that demonstrated that the genetic material of phage isn't protein but rather it's DNA.
Based on the information given in the question, the experiment will not work because amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Therefore, the correct option is E.
The answer is Brachial Plexus. Brachial Plexus Injury is the result of pulling or stretching the arm forcibly. Sudden damage to the nerves, weakness, loss of sensation and movement are the most common symptoms of a brachial plexus injury.
The correct answer is b, photosynthesis.
