The answer is (B): Desulfovibrio.

Explanation for each option:

(A) Lactobacillus - This is considered a "good" gut bacterium. It is commonly found in the human gut and is known for its role in fermenting lactose and other sugars, producing lactic acid, and contributing to a healthy gut environment.

(B) Desulfovibrio - This is not typically considered a "good" gut bacterium. It is a sulfate-reducing bacterium that can produce hydrogen sulfide, which in high amounts can be harmful to the gut lining and is associated with certain gut disorders.

(C) Bifidobacterium - This is considered a "good" gut bacterium. It is known for its beneficial effects on gut health, including aiding digestion and boosting the immune system.

(D) Fecalibacterium spp - This is considered a "good" gut bacterium. It is one of the most abundant and important bacteria in the human gut, known for its role in producing butyrate, a short-chain fatty acid that supports gut health.

(E) Roseburia - This is considered a "good" gut bacterium. It is involved in the production of butyrate, which is beneficial for maintaining a healthy gut lining and reducing inflammation.

In summary, Desulfovibrio is the exception as it is not typically classified as a "good" gut bacterium.

There is a bag with three balls numbered 1 to 3. There is also a pack of three cards lettered K, Q, and J. As a trial of an experiment, a ball was chosen and a card drawn. The number (1 to 3) of the ball and the letter (K, Q, or J) of the card drawn were recorded. Here is a summary of the data from 1375 trials. 1 K 2 K 152 156 2 K 3 K 156 153 1 3 K 1 153 147 1 Q 2 Q 147 157 2 Q 3 Q 157 150 15 1 J 2 J 159 155 3 J 146 Answer each part. Assuming the ball was chosen and the card was drawn at random, find the theoretical probability of this event: both choosing the 1 or 2 ball and drawing the Q card, in a single trial. Round your answer to the nearest thousandth. (II) (b) Use the data to find the experimental probability of this event: both choosing the 1 or 2 ball and drawing the Q card, in a single trial. Round your answer to the nearest thousandth. (c) Choose the statement that is true. - The experimental probability will never be very close to the theoretical probability, no matter the number of trials - The larger the number of trials, the greater the likelihood that the experimental probability will be close to the theoretical probability - The smaller the number of trials, the greater the likelihood that the experimental probability will be close to the theoretical probability.

For many people, breakfast cereal is an important source of fiber in their diets. Cereals also contain potassium, a mineral shown to be associated with maintaining a healthy blood pressure. An analysis of the amount of fiber (in grams) and the potassium content (in milligrams) in one serving of 77 breakfast cereals produced the regression model Potassium = 38+27 Fiber. From this model you can estimate a cereal's potassium content from the amount of fiber it contains. In this context, what does it mean to say that a cereal has a negative residual? What does it mean to say that a cereal has a residual of -22 ? What does it mean to say that a cereal has a residual of -22 ? A. A residual of -22 means that particular cereal has 22 mg more potassium than the model predicts. B. A residual of -22 means that particular cereal has 22 mg less potassium than the model predicts. C. A residual of -22 means that particular cereal has 22 g more fiber than the model expects. D. A residual of -22 means that particular cereal has 22 g less fiber than the model expects.
