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.

- Why 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_forwardMicrobiologists have announced the discovery of over 30 new species of bacteria that thrive between the teeth and gums of humans. The bacteria could not be grown in the researcher's laboratories, nor were any of them ever observed via and kind of microscopy. If they couldn't culture them or see them, how could the researchers know they discovered a new species? If they couldn't examine the cells for the presence of a nucleus, how did they determine that the organisms were prokaryotes and not eukaryotes?arrow_forwardNeed 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. For example: for an acid fast cell wall requires a specialized stain, and then a microscope to view.arrow_forward
- Movement of bacterial cells was discussed at length in the bacterial structures simulation. What structure allows bacteria to be motile? List 2 advantages to being a motile bacterial?arrow_forwardWe 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. (If we had sampled other environments outside in nature, we would have found plenty of bacteria.) Based on these two pieces of information, explain whether bacteria could survive under sunshine? Give a logical reason.arrow_forwardPenicillin inhibits bacterial growth by preventing the cross-linking during peptidoglycan synthesis. Why does penicillin not inhibit growth of archaeal cells? Group of answer choices Most archaeal cells have a cell wall, but it is not composed of peptidoglycan. Archaeal cells do not have a cell wall. Penicillin is unable to penetrate the lipid outer membrane that blocks access of penicillin to the peptidogycan crosslinking enzymes. Pencillin is unable to penetrate the S layer to reach the peptidoglycan layer underneath.arrow_forward
- what are three cellular parts that are specific to ALL bacteria? This should not include any cellular parts listed that both prokaryotes and eukaryotes will have. This also should not include cellular parts that only specific types of bacteria will have (example: flagella). Then state the function of the cellular part (what does it do for the cell?arrow_forwardWhat are the flaws ? Prokaryotes can live in many different environments. Anerobic organisms need oxygen to survive, while aerobic organisms can survive without oxygen. Autotrophs are organisms that can assemble high energy macromolecules for their energy. Chemotrophs are organisms that capture energy from light. Extremophiles are organisms that grow in extreme conditions like boiling water. Gram-positive bacteria have few layers of peptidoglycan, while gram-negative bacteria have many layers of peptidoglycan and are surrounded by an outer membrane. Harmful bacteria can cause illness like food poisoning. Helpful bacteria can be used in food production to make yogurt. The endosymbiotic theory states that some of the organelles in eukaryotes were once free living prokaryotes. This is supported by the mitochondria and cytoplasm since they have their own DNA and ribosomes. Harmful protists can cause diseases like malaria in humans and downy mildew in plants. Helpful protists can be…arrow_forwardTRY TO KEEP IN SHORT AND USE OWN WORD FOR THIS QUESTION You are studying a type of bacteria isolated from the acidic water runoff of a mining operation. You subject two batches of the same bacteria type to different environmental growth conditions. One batch is grown at pH 2, while the other is grown at pH 7. All other environmental parameters are kept identical between the two batches. You then collect their proteins and run a Western blot using an antibody that binds to a proton efflux pump protein (which actively expends energy to pump protons out of a cell). How would you characterize the information obtained in this experiment? What does it tell you, and why is that potentially valuable information?arrow_forward

You then moved the cells to an incubator containing normal atmosphere (i.e., 21% oxygen), completed a second set of measurements, and made the following observations: The rate of cell division increased considerably after the addition of oxygen (aerobic growth) Glucose consumption dropped dramatically after the addition of oxygen Intracellular ATP:ADP ratios increased significantly (from 2:1 in the absence of oxygen to 10:1 in the presence of oxygen) Explain how the mitochondria in the yeast contribute to the dramatic drop in glucose utilization and increase in ATP concentrations in the presence of oxygen.arrow_forwardThe most selectively toxic antibacterial agents are those that interfere with bacterial cell wall synthesis.
