A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cell

Marrrta [24]

Answer:

M phase: 4.8 hr

Prophase: 2.4 hr

Prometaphase: 0.72 hr

Metaphase: 0.24 hr

Anaphase: 0.84 hr

Telophase: 0.6 hr

Explanation:

Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:

M phase: 40/200 = 0.2 x 24 hr = 4.8 hr

Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr

Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr

Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr

Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr

Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr

In the following clinical question, what is the Comparison (C component): Does chronic stress affect inflammatory responses in o

Elanso [62]

Answer:

In the clinical question Does chronic stress affect inflammatory responses in older men with atherosclerotic disease? There is no comparison, so component C does not exist.

Explanation:

C of Comparison corresponds to the PICO process.

The PICO process is used in the resolution of clinical questions, and serves to enumerate the components that allow the analysis of said question. The acronym for PICO corresponds to:

Population
Intervention
Comparison
Outcome

In the approach of a clinical question the comparison is established when it comes to appreciating one characteristic with respect to another:

"Do patients with gastritis improve with gastric protectors or only with diet? "

Here a comparison is established between two therapeutic measures.

In the question "Does chronic stress affect inflammatory responses in older men with atherosclerotic disease?" component C of the PICO process does not exist, because there is no established comparison.
