The characteristics of agar that makes it a useful solidifying agent for growth media is it is unable to be metabolized by most microorganisms. Agar is a common solidifying agent for a culture medium; a complex polysaccharide derived from a marine alga - long been used as a thickener in foods such as jellies and ice cream. Agar has some very important properties that make it valuable to microbiology, and no satisfactory substitute has ever been found. A small number of microorganisms can damage agar so it remains solid. Also, agar liquefies at about 100°C which is the boiling point of water and at sea level remains liquid until the temperature drops to about 40°C. For laboratory use, agar is held in water baths at about 50°C. At this temperature, it does not injure most bacteria when it is poured over them. As soon as the agar has hardened it can be keep warm at high temperature approaching 100°C before it again dissolves and is particularly valuable when thermophilic bacteria are grownup.
Answer:
1. The physiological changes that will occur when someone lives at altitude for an extended period include increased production of more red blood cells.
2. The changes are advantageous as the person can survive lower altitude better and strenuous activities that interferes with breathing.
3. The specific physiological pathway that results in the changes described involves decrease in pulmonary ventilation at high altitude leading to hypoxia then hypoxemia. The body then produces more red blood cells to counteract the lower oxygen saturation in blood in high altitudes.
Answer:
the bacterial cell will die since it cannot replicate or transcribe its DNA
Explanation:
DNA is a double stranded molecule that stores genetic information in living cells. However, the DNA needs to be replicated before cell division and also transcribed in order to be expressed.
As stated in this question, DNA helicase is an important enzyme in the replication and transcription of DNA because it is the enzyme responsible for separating the double stranded DNA into single strands before they can be replicated or transcribed.
According to this question, fluoroquinolones such as ciprofloxacin, are synthetic drugs that interfere with the action of DNA helicases in a cell. This means that a cell affected by this synthetic drug will be unable to separate it's DNA and hence, will die since it cannot replicate or transcribe its DNA.
