I would believe C because the water isn’t disappearing the plants/mud are taking up space.
If one strand of a DNA molecule has the sequence of bases 5-ATTGCA-3, the mRNA synthesized following the template will be 3-UAACGU-5.
Nucleotides are added to the growing strand one at a time in the precise sequence dictated by the existing template strand. adenine and thymine are always paired with each other in the Watson-Crick DNA model, and cytosine is always paired with guanine.
The nucleotide sequence of DNA serves as a template for the nucleus, where mRNA is synthesised. The RNA polymerase II enzyme is responsible for this reaction's catalysis and needs nucleotide triphosphates as its substrates. Transcription is what happens in the nucleus when DNA is converted into mRNA. The cytoplasmic synthesis of proteins is controlled by the mRNA. The cytoplasm is where the mRNA that is produced in the nucleus attaches to the ribosomes after being transported from the nucleus. The nucleotide sequence of the mRNA serves as a guide for the assembly of proteins on ribosomes. The cytoplasm receives a "message" from the nucleus via mRNA. The nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the messenger RNA, encodes the message.

Bacteria cells have no *nucleus*
Reason:
Prokaryotic cells lack most organelles, namely the nucleus, which contains genetic information and controls everything that goes on in the cell. Bacteria cells are prokaryotes, which means they do not have many of the organelles that eukaryotic cells have.
Answer:
Sympatric speciation
Explanation:
Reproductive isolation is the phenomena where two groups of organisms are not able to interbreed because of many mechanical, spatial or temporal barriers. It ultimately leads to formation of two different species. It can occur by allopatric speciation or sympatric speciation.
In allopatric speciation, the groups are not able to interbreed because they are geographically isolated. However sympatric speciation occurs in the same geography. The two groups inhabit the same area but are still not able to interbreed because gene flow is prevented between them. For example, in plants polyploidy can occur due to random mutation. Such a plant will not be able to mate with other plants of same species in the same area because of different chromosome number. Hence, it becomes reproductively isolated from rest of the plants in the area.
