b. absent or diminished levels of progesterone

Explanation:

Dysfunctional uterine bleeding refers to abnormal uterine bleeding that causes the endometrial line to shred off in an abnormal manner.

Fibroid tumor, endometrial  inflammation and malignancies are indirect causes of uterine bleeding but most common cause is the hormonal imbalance.

Progesterone is responsible for development and maintenance of endometrium so absent or diminished levels of progesterone is the cause of DUB.

vodomira [7]

Answer:

Option a (manipulated variable) would be the appropriate choice.

Explanation:

  • To analyze the influence on something like a dependent variable, another modified variable seems to be an important variable responsive to modifications in quite an analysis.
  • Plainly defined, the variable has been adjusted to determine its effect on the overall outcome of the study. There would be only one manipulated component in a correctly planned analysis.

The other options offered are not relevant to the situation described. So, the solution above is the best one.

<u>Answer</u>: Bacteria through the nucleoid (number 5).

<u>Explanation</u>:

Both paramecium and bacteria are single celled organisms. However, they differ by the fact that the first one is an eukaryote and the second one a prokaryote.

Furthermore, they differ in their capacity to mutate and adapt to environmental changes. Bacteria have a simple internal structure that lacks any organelles and are very adept at adapting to environmental changes. Besides their capacity for high mutation rates, they are also capable of picking up genetic information from their environment through a process called <em>transformation</em>.

Through transofrmation, environmental DNA enter the living bacteria through its cell membrane. Double stranded DNA will have one strand dissolved through hydrolysis, whereas the second strand may recombine with the bacterial <em>chromosome (nucleoid)</em>. Thus, this new genetic material will become incorporated into the bacterium's genome.
