Answer:

True

Explanation:

RNA interference is one of the cell's mechanism to regulate gene expression. Two classes of RNA, micro RNA (miRNA) and small interfering RNA (siRNA) are responsible for post transcriptional gene regulation. RNA interference can also help to fight against viral infection. They prevent the transcription of viral gene and in some cases also lead to its degradation by initiating attack from various protein complexes called as ribonucleases.

Energy used by the body to perform muscular contractions is called adenosine diphosphate, or ADP.
Bezzdna [24]

Answer:

The energy used for muscular cont ration is ATP(adenosine triphosphate) This is the energy currency produced in the mitochondrial during cellular respiration.

During muscles contraction.The ATPs is broken down to ADP and Pi.

This is the breakdown of energy rich bonds binding phosphate ions with ATP.The breakdown of the bonds produced -32kJper the 3 bonds in ATP. Therefore as each bond is broken, energy is produced for muscle contraction

It is an exergonic reaction with production of heat.

Thus ATP is used for muscle contraction.ADP is the intermediate of ATP when one Phosphate is removed during the breakdown.

Thus the sequence is Adenosine triphosphate (3 phosphate) to Adenosine diphosphate(2 phosphate) to Adenosine monophosphate (1 phosphate)

Each bond breakin gives equal energy of -32kJpermol.

Plant cells have plastids and larger vacoule and they also have tough cellulosic cell wall outer to cell membrane as a covering.

Animal cells don't have cell wall rather they have cell membrane as it's outermost covering and they have smaller vacuoles.They also don't have plastids.They have centrosome which is not found in plant cells.
