Answer:
Question 1
D
Question 2
C
Question 3
D
Explanation:
1. An ecosystem is MOST likely to return to its original condition after Tall prairie grass burns after being struck by lightning.
Here is a research paper in which they explained how this happened. (Komarek, E. V. (1971). Lightning and fire ecology in Africa. In Tall Timbers Fire Ecology Conference (Vol. 11, pp. 473-509).)
2. In some national parks, controlled fires are maintained by firefighters. The major reasons for using controlled burns to maintain certain ecosystems is to give nonnative plants a chance to colonize the region.
A recent article provided the insight of this situation (Xanthopoulos, G., Delogu, G. M., Leone, V., Correia, F. J., & Magalhães, C. G. (2020). Firefighting approaches and extreme wildfires. In Extreme Wildfire Events and Disasters (pp. 117-132). Elsevier.)
3. One reason for the change in the Galápagos ecosystem has been the introduction of species that were not on the island before, such as donkeys, goats, cats, dogs, and insects. The introduction of nonnative species MOST likely disrupt the balance of life on the islands due to greater competition for limited food sources.
Scientist said that food competition is actually a struggle to survive in any ecosystem here is the reference paper (Eckhardt, R. C. (1972). Introduced plants and animals in the Galapagos Islands. Bioscience, 22(10), 585-590.)
Molecular homology, because it compares dna
I’m going for real I haven’t done this because it was hard didn’t get it but now I know // ANSWER -
Answer:
I think the answer is C I hope you get this right, tell me if I am wrong plz
Explanation:
<u>In the process of translation, the statement stands correct and applies are as follows:</u>
- The ribosome has two sub-units that work together.
- Amino acids are joined by peptide bonds.
- Each tRNA brings in exactly one amino acid that corresponds to the anti-codon.
- The order of the amino acids is determined by the mRNA which is transcribed from DNA.
Answer: Options A, B, C, and E
<u>Explanation:</u>
In the process of translation, ribosomes are the structural unit where the translation is being performed and it has the two sub-units which enact together the translational process.
Any two amino acids are bonded together by peptide bond and tRNA brings one amino acid at a time which corresponds to the anti codon. The order of amino acids is determined by mRNA transcribed from the DNA, and not from the ribosome. Thereby, all given options are correct except the option D.
