The Bunsen burner has a controllable air supply and a constant gas jet, therefore when the air supply is reduced; a highly visible, yellow/orange ‘safe flame’ is produced. For heating work, the air inlet is opened and the burner produces a much hotter blue flame. Therefore, the two flames produced by a Bunsen burner can … Read more
What Are Ruminant Animals? Ruminants also referred to as ‘’polygastrics’’ are herbivores with a complex (four-part stomach) which allow them to chew food more than once. Parts of their stomach structure include, Rumen, Reticulum, Omasum and abomasums. The rumen and the reticulum are connected and work in concert and are therefore sometimes referred to as … Read more
