Answer:
Bacteria that are oxidase-negative may be anaerobic, aerobic, or facultative; the oxidase negative result just means that these organisms do not have the cytochrome c oxidase that oxidizes the test reagent. They may respire using other oxidases in electron transport.)
Answer:
C. Ethanol, ammonium chloride, phosphate buffer, magnesium sulfate, calcium chloride, trace elements
Explanation:
Acetobacter must have a sufficient supply of oxygen and cannot grow in its absence. Colonies of acetobacter can be detected by a culture media containing ethanol as carbon source, the acid produce by the bacteria will dissolve the chalk thereby leaving a clear zone around the colony.
<h2>Homologous genes get Highly Conserved</h2>
Explanation:
- Eukaryotes are those organisms whose cells possess a nucleus which is enclosed within membranes.
- Plants such as Apple trees
- Animals such as Dogs and cats
- Fungi such as Mushrooms
- Protists such as Paramaecium
- Amoeba are the examples of Eukaryotes.
- Eukaryotic cell possess several rod shaped chromosomes.
- Eukaryotic cells contain membrane bound organelles such as Golgi apparatus and Mitochondria, Chloroplast.
- Asexual and Sexual types of reproduction is seen in Eukaryotes.
It refers to the idea the prehistoric oceans combined with lightning formed the building blocks of life.
Explanation:
The primordial soup refers to the idea that prehistoric oceans combined with lightning to form the building blocks of life.
The soup can be regarded as the soup of life through which the first nuclei acids were synthesized.
- It was a hypothesized set of conditions available when the earth was initially formed about 4.5 billion years ago.
- The miller-urey experiment was set up in 1930's to demonstrated this soup of life.

It won't. Argon is an element found in the Group 8A also called as the noble gases. They are called as such because they do not react with other elements because their electronic configuration is very stable. This is because they already obey the Octet rule, which has to do with eight electrons occupying around the element. So, it is very rare to have reaction involving any of the noble gases.
