The answer is: protection.

Explanation for each option:

  1. Gathering nutrients: The sheath in sheathed bacteria is not primarily involved in gathering nutrients. Nutrient uptake is typically managed by the cell membrane and other cellular structures.

  2. Protection: The sheath serves as a protective layer for sheathed bacteria. It helps shield the bacteria from environmental stresses, such as desiccation, predation, and harmful substances.

  3. Gene transfer: While some bacteria have mechanisms for gene transfer, the sheath is not directly involved in this process. Gene transfer typically occurs through processes like conjugation, transformation, or transduction.

  4. Reproduction: The sheath is not directly involved in the reproduction of bacteria. Bacterial reproduction usually occurs through binary fission, which does not require a sheath.

In summary, the sheath in sheathed bacteria primarily serves a protective function.

Determine whether the following procedure results in a binomial distribution or a distribution that can be treated as binomial (by applying the 5% guideline for cumbersome calculations). If it is not binomial and cannot be treated as binomial, identify at least one requirement that is not satisfied. In a Pew Research Center survey of 100 subjects, the ages of the respondents are recorded. Choose the correct answer below. A. It is binomial or can be treated as binomial. B. It is not binomial because the probability of success does not remain the same in all trials. C. It is not binomial because there are more than two possible outcomes. D. It is not binomial because there are more than two possible outcomes and the trials are not independent.

For a one-tailed hypothesis test where you reject H0 only in the lower tail, the critical value is -1.3253. What is the statistical decision if tSTAT = -1.64? What is the statistical decision? A. Since the tSTAT value is less than the critical value, do not reject H0. B. Since the tSTAT value is greater than or equal to the critical value, reject H0. C. Since the tSTAT value is less than the critical value, reject H0. D. Since the tSTAT value is greater than or equal to the critical value, do not reject H0.
