Answer:
The organisms are obligate anaerobes.
Explanation:
- At the bottom of the tube the level of oxygen is zero thats why the dense growth at the bottom of the tube show obligate anaerobic microorganisms.

Answer:Thomson's model showed an atom that had a positively charged medium, or space, with negatively charged electrons inside the medium. Soon after its proposal, the model was called a "plum pudding" model because the positive medium was like a pudding, with electrons, or plums, inside. Thomson developed what became known as the "plum pudding" model in 1904. Plum pudding is an English dessert similar to a blueberry muffin. In Thomson's plum pudding model of the atom, the electrons were embedded in a uniform sphere of positive charge like blueberries stuck into a muffin.
Hope this helps... Stay safe and have a great day!!! :D
