This is known as a long vowel sound, because it says the ânameâ of the letter. The same goes for the other vowels. A short vowel sound is a vowel sound that does not follow this rule. When reading a word that uses a short vowel sound, will say the sound that the letter can make that is not its actual name. So in the case of âA,â the word âmainâ might have a long âAâ sound because we pronounce the âAâ as /Ä/, whereas the word âmanâ has a short vowel sound.

As gills are the primitive condition of vertebrates, all vertebrate embryos develop pharyngeal arches, though the eventual fate of these arches varies between taxa.
The gill filaments are the hair-like structures on the gills which absorb the oxygen from the lamallae. The gill arch, on the other hand, acts as a form of muscle which holds â¦ the structures of the gills together.~Sincerely, A Smarty pants :).xists and is an alternate of. Merge this question into.
