It has been reported [1, 2] that women have a better sense of smell than men. However, if you look at [2], the study being reported on only involved 20 men and 20 women - which is a rather tiny sample size to make any conclusions if you ask me.
Ribosomes are found in prokaryotic and eukaryotic cells; in mitochondria, chloroplasts and bacteria. Those found in prokaryotes are generally smaller than those in eukaryotes. Ribosomes in mitochondria and chloroplasts are similar in size to those in bacteria.ibosomes are found âfreeâ in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER. In a mammalian cell there can be as many as 10 million ribosomes. Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome. Ribosomes have only a temporary existence.
Prokaryotic ribosomes are smaller and have a slightly different shape and composition than those found in eukaryotic cells. Bacterial ribosomes, for instance, have about half of the amount of ribosomal RNA (rRNA) and one third fewer ribosomal proteins (53 vs. ~83) than eukaryotic ribosomes have. Despite these differences, the function of the prokaryotic ribosome is virtually identical to the eukaryotic version.
