Two well-understood sncRNAs in eukaryotic cells are: microRNA and siRNA. SncRNAs are small non-coding RNAs with the main function in the regulation of different stages in gene expression. micro RNA are involved in RNA silencing (negative gene expression) and post-transcriptional regulation of gene expression(microRNA is complementary to a part of mRNA and can inhibit translation of that mRNA). siRNAs also <span>called</span> silencing RNA because of their possibility to inhibit translation by degrading mRNA after transcription.
Answer:
C. They pollinate the flowers that only open at night.
Explanation:
A niche is the functional role an organism performs in the ecosystem. Simply, the question is asking for the role of nocturnal animals as pollinators.
- A pollinator is any organism the helps plants to transfer pollen grain from the anther of one flower to the stigma of another.
- This way, fertilization and crossing of genetic materials is achieved.
Nocturnal animals are animals that are very active at night. This is an evolutionary advantage for them because there is less danger at this point of the day.
Therefore, some nocturnal animals can help to pollinate flowers that only open at night.

New capillaries that stem from intact capillaries are delicate and take time to become as stable as the preexisting capillaries.
<h3>
What causes bleeding?</h3>
When skin is cut with a sharp object, it begin to bleed. This is because blood vessels in that area are damaged. Bleeding serves a useful purpose because it helps to clean out a wound but too much bleeding can cause adverse effect on your body so we can conclude that New capillaries that stem from intact capillaries are delicate and take time to become as stable as the preexisting capillaries.
