Ptolemy could not explain * Retrograde motion of the planets* with out epicycles and deferents.
The first step of aerobic cellular respiration to evolve is
glycolysis, the evidence that there is to support this is with through the
cytosol of the cytoplasm in which this stage takes place as this is the process
where glucose has been split in two molecules by the enzymes.
<u>Reason for important to prevent the spread of germs -</u>
- When we unintentionally touch our eyes, nose, or mouth with infected hands, the disease-causing bacteria can spread from infected individuals or from contacting the infected surface.
- We can't always keep our hands free of pathogens that cause disease since we engage in several activities that cause our hands to become contaminated with germs.

Ans.
Protein synthesis involves two stages, named as transcription and translation. During transcription, information present in DNA molecule is used to make mRNA molecule, while translation involves formation of polypeptide chain or protein by using information present in mRNA in the form of codons.
Prokaryotic organisms lake true nuclei, hence in these organisms both transcription and translation take place in cytosol. In eukaryotic organisms, transcription takes place in nucleus, while translation takes place in ribosomes, present in the cytosol.
