Answer:
Most plant can't grow in darkness because they need energy from light to carry out photosynthesis
The principle of competitive exclusion states that two species cannot occupy the same niche.
<h3>
What is competitive exclusion?</h3>
- Two species cannot coexist in the same ecological niche for very long without one becoming extinct or being driven out because of competition for limited resources.
- In Britain, the red squirrels have displaced the grey squirrels as an example of competitive exclusion.
- Due to diseases, competitive exclusion, and the elimination of hazelnuts, there were fewer red squirrels.
- Red squirrels were eventually displaced by gray squirrels, who quickly adjusted to their surroundings.
- Two species with identical niches cannot survive indefinitely, according to the "competitive exclusion principle" (CEP).
- According to the competitive exclusion principle, only one conclusion is feasible when two competing life forms try to inhabit the same niche: One of them will extirpate the other.

Antigen: is a a foreign substance or toxin that causes a immune response.
Antibody: it is a blood protein that is produced in response to an antigen.
White blood cell: also called a leukocyte and is a cell that counteracts against antigens.
Specific: If your're talking about the biology definition then it is, of or pertaining to a species.
Pathogen: a virus or bacteria that can cause a disease.
yeah sure just post something or give meh the problem and ill do it for chu
Complete question:
Question: In prokaryotes, genes can exist as operons that are transcribed into a polycistronic mRNA, containing multiple genes in a single transcript. In eukaryotes, transcripts exist only as monocistronic mRNA containing a single gene. What fundamental genetic difference is responsible for this distinction?
(A) mRNA is transported outside of the nucleus in eukaryotes.
(B) Prokaryotic mRNA has a five-prime GTP cap.
(C) Prokaryotes use a single start codon for multiple genes.
(D) In eukaryotes, each gene has its own transcription initiation site
Answer:
(D) In eukaryotes, each gene has its own transcription initiation site
Explanation:
Eukaryotic mRNAs are monocistronic in nature which means that one mRNA carries the single transcript to be encoded. Each monocistronic mRNA is encoded by a stretch of a gene that has a specific initiation site to start the process of transcription. On the other hand, prokaryotes have some mRNAs that carry the code for two or more different polypeptides. These mRNAs are called polycistronic. For a polycistronic mRNA, multiple transcripts are transcribed under the single transcription initiation site.
