Question
Chapter 15, Problem 11TYU
Summary Introduction
To propose:
A hypothesis as how the genes of the bacteria present in the organ of a flashlight fish are regulated and organized. The flashlight fish consists of an organ under its eye, which helps in emitting light. There is a bacterium inside the organ that is responsible for emitting the light.
Concept introduction:
Bacteria present in the organ of the flashlight fish have a mutual relation with the fish. The bacteria get its nutrient from the fish and the fish startles the predators and attracts prey with the help of the light that the bacteria emit.

Subject: Microbiology
The author of a general biology textbook writes in reference to the development of antibiotic resistance, “The speed at which bacteria reproduce ensures that sooner or later a mutant bacterium will appear that is able to resist the poison.” How might this mutant bacterial cell appear? Do you agree with the statement? Does this bode ill for the future use of antibiotics?

- This lab simulation will use an instrument called a spectrophotometer. This instrument quantitatively measures the amount of light that is absorbed or transmitted by molecules in solution. Different cells and culture media absorb best at a specific, known, wavelength. In this case the amount of light transmission is related to the number of bacteria present. Optical Density is the value given to the measurement of turbidity. Environmental factors, such as temperature and pH, can disrupt the structure of enzymes, resulting in denaturation and making them unable to function.The growth of microorganisms can be controlled in the laboratory by altering environmental factors, such as temperature, oxygen content, osmotic pressure, and pH. write in your own words the Microbial Growth - Effects of pHarrow_forwardplease choose correct letter and explain a bit 1. The strongest way by which a protein can maintain its shape is by using:a) ionic bonds b) disulfide bonds c) star war forces d) van der Waals forces 2. If a cell (like an amoeba) would be capable of migrating from one place to another only with movement created from the inside of the cell, then we can say that that movement is done mainly by: a) glycoproteins b) feet c) microtubules d) actin filaments True or False: In eukaryotic cells (such as human cells), the variety and diversity of proteins is much less than the variety and diversity of lipids.arrow_forwardWhy is ultraviolet radiation only sufficient for the disinfection of surfaces or air, while x-rays can be used for sterilization? The wavelength of ultraviolet light do not possess sufficient energy to damage bacterial cells. Ultraviolet light has a relatively low degree of penetrability. Many cells have enzyme systems that are able to repair radiation-induced DNA damage. Ultraviolet light is capable of ionizing radiation only.arrow_forward
- IS IT A FACT OR A BLUFF? 1. Bacterial genetic material is composed single stranded DNA as compared to human DNA which is double stranded. 2. Just like humans, all microbes need oxygen to grow and reproduce. 3. There are no living microbes in volcanic vent and in hot spring because microbes die at very high temperature. 4. Most bacteria growth is retarded at low temperature. 5. Bacterial ATP production happens in the mitochondria which is the powerhouse of the cell.

You Justification should be given in not more that 50 words.arrow_forwardWhy do hydras have varying colors? I know that for the green hydras, their color was imparted by a symbiotic green algae.

- Need help In a micro lab there are various staining procedures, different microscopes, and media that are used to grow, test, and view microbes. Imagine you are a microbiologist explaining an aspect of the prokaryote and how to work with it in the lab. The options for discussion are endless, its just a matter of tying the two topics together.

- We know that a short duration of UV radiation could kill a large number of the cells. We also know that in the Pure Culture lab a very large number of bacteria existed in the soil.

You will be working with a research associate in the lab to continue characterizing cultured cells (e.g – cells grown in a dish) isolated cells from a complex multicellular eukaryotic organism Onlinus extremus. Preliminary evidence from research in the laboratory has shown that O.Extremus is capable of both fermentation and cellular respiration. While they can survive on a wide variety of questionably food- like fuel sources, like most other eukaryotic organisms', glucose is its preferred fuel source. Practice question 1 and begin expanding the culture (increasing the # of cells) so that you may later conduct experiments on them. You take two aliquots, each with an equal number of cells, and place them in two different culture vessels, one is a sealed airtight flask (culture 1) and the other is an open topped culture dish (culture…arrow_forward
