Different life forms adapt to their environment. Stable ecosystem creates a stable environment for life forms. In stable environment, life forms do not have to adapt all the time and their energy can be invested into other life processes, such as growth, reproduction, etc. Stability of ecosystem is important for adjoining ecosystems because that way boundaries and influences could be extended. Stable ecosystems are able to interact and both benefit from each other.
RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.
siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.
<span>The correct answer is the nucleus and the cell wall. Cell walls and Nucleus are only found in specific cells. Prokaryotic cells are cells that do not have definite nucleus in their cells, while Animal Cells do not have cell walls, yet the Plant Cells have cell walls.</span>
Answer:
The root system is always adventitious. The stem is either underground or aerial. The leaves may be microphylls or megaphylls. Their other common characteristics include vascular plant apomorphies (e.g., vascular tissue) and land plant plesiomorphies (e.g., spore dispersal and the absence of seeds).
