Answer: Option A. "Cytoskeleton"

Explanation:

Cytoskeleton can be defined as the network of protein filaments in the cytoplasm eukaryotic cells interlinking from cell nucleus to cell membrane.

There are three basic types of protein fibers present in cytoskeleton that includes micro filaments (Actin filaments ), microtubules and intermediate filaments.

Microfilaments are consist many linked monomers of a protein known as actin, that combines in a double helix with a diameter of about 7 nano-meter and functions as serving tracks for myosin (motor protein).

Microtubules are arranged in a form of hollow straw like structure made up of consist of tubulin proteins having diameter of about 25 nano-meter and further consist of two subunits, α-tubulin and β-tubulin.

Intermediate filaments are the cytoskeletal element which are made up of multiple strands of fibrous proteins wounded together having an average diameter of 8 to 10 nano-meter.

Exposure Status Cases Controls Yes 11 108 No 5 436 Total 16 544 Calculate the odds ratio. What do you conclude based upon your r

seraphim [82]

Answer:

$Ratio = 8.8$

The exposure may be risk factor.

Explanation:

Given

$\begin{array}{ccc}{Exposure\ Status} & {Cases} & {Control} & {Yes} & {11} & {108} & {No} & {5} & {436} & {Total} & {16} & {544} \ \end{array}$

Required

The odd ratio

First, we calculate the odds of exposure using:

$Odds = \frac{With\ Exposure(Yes)}{Without\ Exposure (No)}$

For cases, we have:

$Odds_{Cases} = \frac{11}{5}$

$Odds_{Cases} = 2.20$

For controls, we have:

$Odds_{Controls} = \frac{108}{436}$

$Odds_{Controls} = 0.25$

So, the odds' ratio is:

$Ratio = \frac{Odds_{Cases}}{Odds_{Controls}}$

$Ratio = \frac{2.20}{0.25}$

$Ratio = 8.8$

Conclusion about the odds' ratio

The calculated ratio is greater than (and also far from) 1.

This implies that there is a greater exposure than the controls.

So, we can conclude that the exposure may be risk factor.

What prompted the search for endorphins? coursehero

Maurinko [17]

When you exercise, your body releases chemicals called endorphins. These endorphins interact with the receptors in your brain that reduce your perception of pain. Endorphins also trigger a positive feeling in the body, similar to that of morphine.
