RNA interference is a biological process in which RNA inhibit gene expression by neutralizing targeted mRNA molecules. RNA interference is usually brought about by two different small RNA; they are microRNA and small interfering RNA.
False, that is one thing many people were always doing, back then.
The ecosystem requires a constant input of energy because energy cannot be stored. The enrgy always gets converted for supporting life in the ecosystem. Some amount of energy is also lost during this conversion. So if there is not a constant supply of energy, then the ecosystem will ultimately breakdown. In case of humans, the energy is received by consuming food. The energy of the food geets converted to the enrgy that helps a human being to complete his daily chores. So energy is being lost at every step. To regain this energy the humans have to eat food regularly. This way the humans need a constant supply of energy to survive. It is the same in the case of all living things in the ecosystem.
Answer:
The correct answer is E. Biological.
Explanation:
The biological definition of species states that while two organisms can mate and have successful and fertile breed, then they belong to the same species. Therefore, if there were no genetic flow between both species, it means that mating and breeding were not successful and therefore, they were not the same species.
Reproduction is the process of making copies.
In an office, the photocopy machine reproduces documents.
In nature, people, plants, and animals reproduce themselves,
and their species continue on Earth when they die.
