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..

검증된 단계별 안내

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.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

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.

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.

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.
