select the three best hypotheses that could explain why the broth in the durham tube appears yellow while the rest of the broth
Tamiku [17]
The test organism ferments sucrose best under reduced oxygen conditions.
The sample was incubated less than 24 hours, which allowed for only limited fermentation.
The media was contaminated.
The organism is an obligate aerobe and therefore can only grow inside the Durham tube.
The media was prepared wrong.
The organism is limited in its ability to ferment sucrose. Since diffusion is restricted within the Durham tube and it contains only a small volume of media, it turned yellow first.
The test organism did not ferment sucrose.

1)The test organism ferments sucrose best under reduced oxygen conditions.
2)The sample was incubated less than 24 hours, which allowed for only limited fermentation.
3)The organism is limited in its ability to ferment sucrose. Since diffusion is restricted within the Durham tube and it contains only a small volume of media, it turned yellow first.

when iron rusts and forms iron oxide, the iron oxide has more mass than the iron. which statement correctly explains this observ
GarryVolchara [31]

The reason why iron oxide has more mass than the iron is because Iron oxide has oxygen atoms, and pure iron does not.

When iron rusts and forms iron oxide, the iron oxide has more mass than the iron. Which statement correctly explains this

observation?

(A)Iron oxide has oxygen atoms, and pure iron does not.

(B)The oxygen atoms in iron oxide have more mass than the iron atoms in pure iron.

(C)The iron atoms in iron oxide have more mass than pure iron.

(D)There are more iron atoms in iron oxide than in pure iron.

When a chemical reaction takes place, other atoms are combined with pure elements to form compounds. This addition of another atom (oxygen) after reaction makes iron oxide formed heavier than pure iron.

Iron oxide is a chemical substance formed when pure iron rusts. The formation of iron oxide is a chemical reaction.

Hence, the correct answer to the question is;  the iron is heavier  because Iron oxide has oxygen atoms, and pure iron does not.
