Available options are:
A. a scientific inquiry is used only by scientists.
B. scientific inquiry is a process of asking and answering questions.
C. scientific inquiry has only one correct pathway.
D. scientific inquiry often involves similar processes and practices.
E. scientific inquiry involves performing investigations and collecting data.
Answer:
B, D, E
Explanation:
Given that scientific inquiry is a term that described how people mostly scientists, observe the natural world and then come out with credible justification established on the findings that were derived.
Hence, the statements that describe scientific inquiry are:

Answer:
of the low pH of the vagina.
Explanation:
The pH of the vagina is maintained at highly acidic levels to prevent the germ buildup. The range of vaginal pH is around 3.8 to 4.5. The very low pH of the vagina creates a hostile environment for sperms and most of the sperms are killed as they enter the vagina due to the acidic pH.
Apart from supplementing the sperms with energy, cervical mucus serves to protect the sperms from the hostile conditions of the vagina. The cervical mucus has an alkaline pH at or near the ovulation to protect sperms from acidic pH of the vagina and to facilitate fertilization.
Answer:
B. They have a single small nucleus.
Explanation:
The presence of large nucleus is a characteristic feature of cells that frequently undergo cell division. Cancer cells are characterized by uncontrolled continuous cell division even when the new cells are not required by the body.
This leads to the formation of benign or metastatic tumors. To undergo continuous cell division, the cancer cells have a large nucleus. The nucleus of the cancer cells is mostly hyperchromatic and distinct due to higher nuclear to cytoplasmic ratio. It allows these cells to exhibit the uncontrolled cell division.
