Answer:
Oxygen
Explanation:
C6H1206+602=>6C026H20+ATP
We can see that oxygen is a necessary reactant for cellular respiration among the other options.
Energy, water, and carbon dioxide are produced. When the chemical bonds of the glucose molecule are broken, energy is released. The cell is able to store that energy in the chemical bonds of a special molecule called adenosine triphosphate or ATP
Answer:
The culture medium must be selective
Explanation:
Selective media are the media that have those ingredients which favor the growth of a particular bacterium and inhibit the growth of unwanted bacteria. So a selective media is used to selectively grow a particular micro-organism.
For example, MacConkey agar is a selective media that is used to isolate gram-negative enteric bacteria based on lactose fermenting ability. It contains ingredients like bile salt and crystal violet which inhibits the growth of gram-positive bacteria therefore it only allows the growth of gram-negative bacteria.
<em>Staphylococcus</em> <em>epidermidis</em> is a gram-positive bacteria and <em>E.coli</em> is gram-negative enteric bacteria so MacConkey agar can be used to select E.coli over <em>Staphylococcus</em> <em>epidermidis</em>. So the correct answer is the culture media must be selective.
