Answer:
It is required that the seed region of the processed dsRNA molecule bind to the mRNA of mex-3 in order to inhibit its translation
Explanation:
Double-stranded RNAs are small interfering non-coding RNAs (about 20 nucleotides in length) that, after processing, can bind by complementary base pairing to RNAs and thus inhibit protein translation by a mechanism referred to as 'RNA interference' (RNAi). The base pairing is not always perfect; however, the guide strands of dsRNAs can conserve their ability to inhibit the translation if the complementarity is enough good to match target RNA sequences. The critical region in the dsRNA that is required to bind target RNAs is known as seed region, and consists of 6 to 8 nucleotides in length.
Answer: homeostasis.
Homeostasis is the regulation of the functions of some internal conditions as reaction to changes in the environment.
For example, although the external temparuture changes the matabolism is capable to keep the temperauture of the body constants through homeostasis.
That does not happen with the cold blooded animals. If you put a small frog very close to a hot ligthed bulb, its blood will not be able to keep it cool and it will dry completely.
Answer:
The first organelle that is found in an animal cell is the cell wall. The cell wall that is only found in plants cells helps the cell with structure. The second organelle not found in an animal cell is the chloroplast. The chloroplast contains chlorophyll and is the site of photosynthesis. Both of these organelles are only in plant cells and not in animal cells.
Explanation:
Answer:
Tetanus is caused by a bacteria called <em>Clostridium tetani </em>which is unicellular.

C, decrease.
If the trait is easy to be seen by predators, they will be caught more often than those without the trait, thus reducing the frequency of the trait.
