Which suggests themicrobiota are inherited by offspring?Panel (a) supports inheritance, and panel (b) supports infection.Panel (a) supports infection, and panel (b) supports inheritance.Neither scenario suggests inheritance. Nodules found on the roots of leguminous plants like soybeans harbor bacteria that fix nitrogen. These nodules are anexample of the intimate and specialized partnerships that have been established over time between prokaryotes andeukaryotes. Coevolution maintains these types of relationships because both participants benefit. Plants receive biologicallyuseful forms of nitrogen needed for growth, and the bacteria reside in an oxygen-free environment required by enzymesinvolved in the nitrogen-fixing process.Humans also maintain intimate associations with beneficial bacteria and even archaea. In fact, the prokaryotic cells in andon human bodies outnumber the eukaryotic human cells by tenfold, according to some estimates. These microbialinhabitants help humans digest food, provide essential vitamins absorbed by the intestines, and even impact the immunesystem.The microbes that coevolve with plants arrive by infection of root tissue. The microbiota that coevolve with humanscolonize human tissues after birth. Consider the chart showing the distribution of the gut microbiota in a human female.FirmicutesMotherOtherBacteroidetesPanels (a) and (b) shown depict two scenarios for the distribution of the gut microbiota in her son. The son maintains asimilar diet in both scenarios and has not undergone recent antibiotic treatment, which would decimate and/or alter theentire gut community.

Human gut microbiota refers to the trillions of microbes like bacteria that live in the human gut.…

Discuss the three stages in the formation of symbiotic nitrogen-fixing associations in legumes.
Antibiotics enter the environment in wastewater from pharmaceutical manufacturing plants, in wastes from farms where they are used in animals, and in sewage from human populations. (Many antibiotics are excreted in their active form.) The influx of antibiotics into the environment is a concern because the presence of these compounds in the environment selects for antibiotic resistance. As pollutants, antibiotics can also have ecological effects. Describe some of the ecological roles of bacteria, and explain why disruption of these roles by antibiotic pollution would have a negative impact.
Evidence indicating the chloroplasts were originally free-living prokaryotes that subsequently evolved a symbiotic relationship with a eukaryotic host includes all of the following except: Ability of chloroplasts to synthesize all their own proteins Presence of circular DNA in chloroplasts and in free-living prokaryotes Similarities of rRNA sequences between chloroplasts and free-living prokaryotes Similarities of structures between chloroplasts and some contemporary free-living prokaryotes C
Give examples of free-living and symbiotic nitrogen-fixing microorganisms. Are these prokaryotic or eukaryotic?
The endosymbiotic hypothesis for the origin of chloroplasts from gram-negative prokaryotes is supported by all of the following lines of evidence except: the presence of enzymes for the light-dependent and the dark reactions of photosynthesis the presence of circular DNA resembling that of photosynthetic eubacteria the presence of mRNA, tRNA, and rRNA similar to that of the cyanobacteria their use of mitosis rather than binary fission during cell division the presence of 70s ribosomes, consisting of 30s and 50s ribosomal subunits
We have seen that energy is essential for life on earth. All organisms need energy to maintain their cellular processes. There are two basic ways of generating energy de novo, at the base of food webs. Describe the two primary ways that autotrophic organisms generate energy, including the original source of energy and the primary organisms that carry out each process.
In cyanobacteria, nitrogen fixation takes places in specialized cells called heterocysts nitrospores Othylakoids Ochloroplasts
The unicellular cyanobacterium Prochlorococcus sp. is the most abundant photosynthetic microbe in tropical and subtropical oceans. At least two ecotypes exist: one is adapted to high light and the other to lower light intensities. How does the presence of these two ecotypes contribute to their physiological success and their numerical success? How would you determine the amount of fixed carbon they contribute to these open-ocean ecosystems?
In what ways are the prokaryotes metabolically diverse? How is this diversity helpful with respect to nutrient cycling? Useful in bioremediation?
The degradation of complex molecules in soil by fungi for utilization by bacteria is an example of which type of association?
In the early 1930s, G. F. Gause carried out a series of experiments using two species of ciliated protists (Paramecium), which are single-celled eukaryotic protozoans. The protists were cultured together and separately, with the bacteria being the single food source. The results are shown in the figure below. (a) Based on figure, identify and explain the interaction that is taking place between P. caudatum and P. aurelia. (b) Clam shrimp, a natural predator to P. caudatum, is introduced to the culture containing both P. caudatum and P. aurelia after 24 days. Predict the impact that the clam shrimp will have on the culture and the populations. Justify your prediction.
In a population of cyanobacteria (Chlorogloeopsis fritschii) in a hot spring in Iceland, some of the bacteria can produce chlorophyll f, while some C. fritschii produce only other types of chlorophylls. Chlorophyll f absorbs light outside of the visible light spectrum, namely near infrared light, allowing the bacteria to absorb light that has not been absorbed or reflected by the water or other organisms. The ability to produce chlorophyll f is heritable, and the bacteria with chlorophyll f can live in low-light environments, such as underneath other organisms, or near the bottom of the light-penetrating zone of the spring. What is the adaptation in this population of C. fritschii living in low-light environments? (Choose one.) a) the ability to produce chlorophyll f b) the ability to produce any type of chlorophyll c) the ability to tolerate the high temperatures of the hot spring d) the ability to survive and reproduce
