A) cellular respiration because fermentation takes place without oxygen(anaerobic)
The concentration of the cell and that of its environment
The correct answer is a colon.
<span>
The bacterial flora of the gastrointestinal tract is very diverse, especially in the large intestine (colon) which has the richest microflora. The main types of microorganisms in the colon are obligate anaerobes, and the most abundant bacteria are Bacteroides. Functions of the microflora are useful for hosts such as protective function, <span>prevention of growth of harmful species, regulation of the development of the gut, production of vitamins for the host (</span><span>vitamin K<span>) and hormone producing.</span></span></span>
This question is in the context of research. The answer is directional or one-tailed hypothesis. This is because the researchers have specific hypothesis that predicts the direction of the experimental effect (i.e. the researcher expects that alcohol consumption slows reaction time). The researcher will then formulate a null hypothesis (H0) that suggests that alcohol does not slow reaction time and another alternative hypothesis (HA) that suggests that alcohol slows reaction time.
