MacConkey agar is a selective and differential culture medium for bacteria designed for isolation of Gram negative and usually enteric bacilli, based on their ability to ferment lactose. It contains bile salts, crystal violet, neutral red dye. There are many variations of MacConkey agar depending on the need. This medium was developed by Alfred Theodore MacConkey. This agar can distinguish gram negative bacterias that can ferment. This is known as the indicator medium.
I believe it is DNA and RNA but don't quote me on it

pneumonia is an infection where the lungs start to fill with fluid.
Cancer is usually a tumour inside the lungs.
The answer would be A
Genetic engineering often means insertion of a gene and
harvest of the protein from huge numbers of bacterial cells.
<span>Hemoglobin, are only functional as an assembly of multiple
sub-units. The ability to efficiently harvest the protein of interest and purify
it away from all the other proteins normally produced by the host cell, is one
of the major limiting factors for the large scale production of genetically
engineered hemoglobin.</span>
Explanation:
Why (for what reasons) is it believed that oxygen was not present when life formed on Earth? The life forms were anaerobic, and did not make oxygen. There is a lack of oxidized iron in rocks that are a few billion years old. Eventually oxygen from the oceans moved into the atmosphere, and iron could be oxidized.
