Chapter 27, Problem 8TYU
SCIENTIFIC INQUIRY • INTERPRET THE DATA The nitrogen-fixing bacterium Rhizobium infects the roots of some plant species, forming a materialism in which the bacterium provides nitrogen, and the plant provides carbohydrates. Scientists measured the 12-week growth of one such plant species (Acachiirrorata) when Infected by six different Rhizobium strains.
(a) Graph the data. (b) Interpret your graph.

The rhizosphere is:Group of answer choices
A.) an area 1-2 mm in thickness adjacent to the root.
B.) Bacteria that assists in the conversion nitrogen gas.
C. ) Fungi that assists in the absorption of micronutrients.
D.) All of the above
Which is false among A-E regarding symbiotic nitrogen fixation?
A) O Initiation of the symbiosis involves communication between the plant and bacteria
B)O Within the plant, the bacteria differentiate into N2 fixing bacteroids
C) O The N2-fixation process is sensitive to oxygen.
D) O The bacteria infect the root of the plant via an infection thread.
E) O None are false; A-E are all true,
For both fertilizers, plant growth began to decrease when 1.5 kg of
fertilizer was given.
D)
Rhizobia are bacteria that live on the roots of some plants, such as legumes like pea plants. Rhizobia convert an element in the
atmosphere into ammonia. Identify and explain the type of relationship this represents.
A)
It is parasitism because the bacteria absorbs food from the pea plant.
It is commensalism because the bacteria and pea plant don't harm each
B)
other.
It is competition because the rhizobia and pea plant both need the limited
amount of available nitrogen.
C)
It is mutualism because the bacteria receives carbon from the pea plant,
D)
Eliminate
while the plant uses the ammopia to make amíno acids.

There are two-main types of nitrogen-fixing bacteria: free-living (nonsymbiotic) and mutualistic (symbiotic). Describe the mutualistic relationship between Rhizobium and legumes. What is the advantage of using legumes as a cover crop in agricultural systems? A point of interest is that the nitrogenase enzyme complex is highly sensitive to oxygen.

From 2014 to 2018, there were 51 foodborne disease outbreaks reported to the CDC linked to leafy greens, but the actual number of illnesses is likely much higher because more foodborne illnesses are not part of a recognized outbreak. Imagine you are a researcher interested in studying the microbial community on leafy greens from many different commercial sources. →You notice that many of the species identified are capable of forming biofilms. You hypothesize that biofilm formation is also important for causing foodborne illnesses. What features of biofilms would make them important in causing foodborne illness from leafy greens?
