For the first question the answer is C. We know this because Dalton considered matter to be composed of very tiny indivisible particles called atoms which means it can't be further subdivided and thus no sub-atomic particles. And for the second question the answer is the Last one: <span>Ernest Rutherford. The rest of them did not give evidence of the existence of a nucleus or gave poor evidence. Hope this helps</span>
The process by which unspecialized cells become specialized into one of many different types of cells, such as neurons or epithelial cells.
mRNA plays a crucial role in protein synthesis. It carries the information for synthesis of a particular protein from the DNA to the ribosomes.
In the cell nucleus, this information is copied (transcribed ) from DNA and onto mRNA. mRNA then leaves the nucleus and enters the cytoplasm where it attaches to a ribosome.
Transfer RNA or tRNA begins to read (translate) the information on the attached mRNA and from the pool of free amino acids in the cytoplasm, fetches the amino acids that corresponds to the information, and brings them to the ribosome where they are linked together into a chain, forming the primary structure of protein.
Unfortunately you didn't support your question with any options so that I could choose the correct one. But I am pretty sure I've got what you need so in eukaryotes, the components of the electron transport chain are located in the <span>inner mitochondrial membrane.</span>
Peristalsis is the name for the waves of contractions that propel substance s along a tract. It is a series of wave-like contractions that moves food to different processing stations in the gastrointestinal tract and starts in the esophagus when the boluses of food are swallowed. The wave motion is produced by the longitudinal smooth muscles that line up the esophagus, stomach, small intestines and the colon and is triggered by presence of food.
