Answer:
By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global).

<h3>Question:</h3>
<em>which type of skeletal muscle fiber is most important for an athlete running a 40 meter sprint</em><em>?</em>
<h3>Answer</h3>
<em>F</em><em>a</em><em>s</em><em>t</em><em> </em><em>t</em><em>w</em><em>i</em><em>t</em><em>c</em><em>h</em><em> </em><em>f</em><em>i</em><em>b</em><em>r</em><em>e</em><em>s</em><em>.</em>
The proportion of days for which the process will shut down for both broth x and broth in the distribution are 2.28 days and 3.34 days.
<h3>How to compute the number of days?</h3>
Mean ( u ) =4.9
Standard Deviation ( sd )=0.6
Normal Distribution = Z= (x - u)/SD
a. P(X > 6) = (6-5.2)/0.4
= 0.8/0.4 = 2
= P ( Z >2)
From the standard normal table.
= 0.0228 = 2.28 days
Broth x = 2.28 days
P(x > 6) = (6-4.9)/0.6
= 1.1/0.6 = 1.8333
= P ( Z >1.833)
From the standard normal table
= 0.0334 = 3.34 days
Broth y = 3.34 days.
The recommendation to the manager as to the broth that should be bought is broth x since it requires lesser days

Answer:
c. cerebrospinal fluid
Explanation:
Cerebrospinal fluid
This fluid is a colorless , clear body fluid , that is present in the brain and the spinal cord .
Some specialized ependymal cells produces this fluid .
Around 125 mL of Cerebrospinal fluid is produced at one time , and around 500mL is produced daily .
The Cerebrospinal fluid is nearly 99% water which means it contain highest volume of fluid .
Cells respond to environmental effects through signal transduction, which promotes healthy cell growth and normal cell function.
<h3>Why is the signal transduction step necessary?</h3>
The reason why after a signal binds to a signal receptor, we need the next step is as follows:
- For the purpose of triggering an appropriate cellular response, living creatures have evolved a vast range of intricate procedures to send signals from the outside to the inside.
- These molecular pathways can develop flaws that result in a variety of ailments, including diabetes, cancer, and psychotic conditions.
- It is the mechanism by which a cell responds to the stimuli it receives from the environment by diffusion of those signals to its internal compartments.
- Signal transduction is the process by which a cell translates a given signal or external stimulus into another signal or specific response.
- First, a particular receptor on the cell's membrane or cytoplasm must be activated by a signaling molecule (also known as a ligand). transduction.
- Ligand-receptor binding is extremely specific; it can be compared to a lock and key.
- Second messengers are chemicals that enable intracellular signal amplification after a signal has been received.
- A ligand's interaction to a receptor may result in the production of hundreds of second messenger molecules, which may then change thousands of effector molecules to cause a variety of reactions.
- Signal transduction enables cells to perceive, interpret, and react to various environmental signals, enabling them to carry out their usual functions.
