The tympanic cavity is an air chamber; it contains a chain of movable bones which transmit the vibrations of the tympanic membrane across the cavity to the middle ear.
Answer:
siRNA.
Explanation:
The RNA interference may be defined as the evolutionary conserved mechanism that helps in the gene regulation by the silencing of the small RNA molecules. Two main types are siRNA and miRNA.
The siRNA (small interference RNA) is involved in the protection of the cell by destroying the exogenous ds DNA of the cell. The DICER enzyme plays an important role in the processing of the small interference RNA and the guide strand of RNA is involved in the gene silencing.
Thus, the answer is option (a).
<span>The correct answer is Some plant and animals are restricted to a particular habitat. That means that they would not be able to live in other habitats either because of natural predators that would eliminate them or because they would ruin the ecological system if they were to interfere with the natural order of things. Things like climate might also affect this.</span>
the answer is Eukaryotic, the first one.. hope it helps
Answer:
When the energy is absorbed in a chemical reaction, we can say that this is an endothermic reaction.
Explanation:
An endothermic reaction is a chemical reaction that absorbs energy instead of releasing energy, like exothermic reactions.
To be considered an endothermic reaction, the chemical reaction must have a low energy reagent and for that reason, they need to absorb energy so that there is a rearrangement of the reactant molecules, forming products with high energy.
