You have inoculated a Clostridium species into a tube of media. After incubation, you observe that there is no growth, and you remember that Clostridium is an obligate anaerobe. What is the best explanation for the observed lack of growth?a. There is not enough water in the environment for Clostridium to grow
b. There is not enough oxygen for use when toxic oxygen is present
c. Oxygen in the medium destroys the enzymes needed by Clostridium to undergo aerobic respiration
d. Clostridium does not have enzymes to process toxic oxygen

D. Clostridium does not have enzymes to process toxic oxygen

Explanation:

Obligate anaerobes are microorganisms killed by normal atmospheric concentrations of oxygen (20.95% O2). Oxygen tolerance varies between species, some capable of surviving in up to 8% oxygen, others losing viability unless the oxygen concentration is less than 0.5%. in other words, Obligate anaerobes are organism which can only live in environments which lack oxygen. Unlike the majority of organisms in the world, these organisms are poisoned by oxygen.

Therefore clostridium do not have enzymes to process this oxygen which is toxic for it

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
