Chapter 11, Problem 10
For each of the following statements that is true, write “true” in the blank. For each statement that is false, write the word(s) that should be substituted for the underlined word(s) to make the statement correct.
__________ When environmental nutrients are depleted, myxobacteria aggregate in mounds to form fruiting bodies..
Verified step by step guidance1
Identify the key concept in the statement: myxobacteria behavior in response to environmental nutrient depletion.
Recall that myxobacteria are known for their social behavior, especially under nutrient-limited conditions.
Understand that when nutrients are scarce, myxobacteria aggregate to form multicellular structures called fruiting bodies, which help them survive harsh conditions.
Since the statement says 'myxobacteria aggregate in mounds to form fruiting bodies' when nutrients are depleted, verify if this description matches the known biological process.
Conclude that the statement is true because the aggregation into fruiting bodies is a well-documented survival strategy of myxobacteria under nutrient depletion.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Myxobacteria and Their Behavior
Myxobacteria are a group of soil-dwelling bacteria known for their complex social behavior. When nutrients are scarce, they aggregate to form multicellular structures called fruiting bodies, which help them survive harsh conditions by producing resistant spores.

Structure of Prokaryotic Ribosomes
Fruiting Body Formation
Fruiting bodies are specialized structures formed by certain bacteria, including myxobacteria, during nutrient depletion. These structures facilitate spore development and dispersal, allowing the bacteria to endure unfavorable environments until conditions improve.

03:08Formation & Breakdown of Polysaccharides
Environmental Nutrient Depletion as a Trigger
The depletion of environmental nutrients acts as a signal for myxobacteria to initiate aggregation and fruiting body formation. This adaptive response ensures survival by transitioning from a vegetative state to a dormant, spore-forming state.
