Sudan changes to deep orange or red in the presence of lipids. Sudan in not soluble in water lipids will absorb sudan's particle that will cause the change in color. Lipids will form distinct fat layer in the solution. This can be done during experiment where a macromolecule is unknown. Application of this experiment applies in health such as during confirmation of excessive fat in stool. The affinity of this dye to the lipids is high and alcoholic solutions of sudan dye can also be used.
The ovary is the expanded inferior part of the carpel. It contains the ovules waiting to be fertilized by pollen.

There is a huge amount of precipitation among the countries situated in the tropical region such as Hawaii or any other tropical island due to its climatic conditions. Since a tropical region receives heat from the Sun directly, the region would eventually be warmer causing more frequent evaporation causing rain.
Given what we know, we can confirm that organisms that can grow with or without oxygen present are referred to as anaerobes.
<h3>What are some examples of anaerobes?</h3>
As stated previously, anaerobes are organisms that do not require oxygen in order to survive, some examples include:
- Staphylococcus
- Escherichia coli
- Listeria
- and many other forms of bacteria.
Therefore, we can confirm that organisms that can grow with or without oxygen present are referred to as anaerobes and they include many forms of bacteria such as the ones listed.
