Quizlet which feature is associated with the maturation phase of normal wound healing

11Alexandr11 [23.1K]

Collagen is referred as the feature which is associated with the maturation phase of normal wound healing through its deposition on the wounded or injured area.

<h3>What is Collagen?</h3>

This is referred as a type of protein which is found in connective tissues and its role is to provide structural support to the different tissues which are found in the body system.

Collagen stimulates new tissue growth by attracting fibroblasts and encouraging deposition of more of it to the affected area. This helps the cells to be formed from pre-exising ones.

This is therefore the reason why collagen was chosen as the most appropriate choice in this type of scenario.

Newton’s law of cooling states that for a cooling substance with initial temperature t0, the temperature t(t) after t minutes ca

antoniya [11.8K]

The cooling rate of the substance is approximately 0.0732.

According to the statement, the Newton's law of cooling is defined by the following formula:

$T(t) = T_{s} + (T_{o}-T_{s})\cdot e^{-k\cdot t}$ (1)

Where:

$T_{s}$ - Final temperature, in degrees Celsius.
$T_{o}$ - Initial temperature, in degrees Celsius.
$t$ - Time, in minutes.
$k$ - Cooling rate, in $\frac{1}{min}$ .
$T(t)$ - Current temperature, in degrees Celsius.

Please notice that substance reaches thermal equilibrium when $T(t) = T_{s}$ , that is when temperature of the substance is equal to the temperature of surrounding air.

If we know that $T_{o} = 80\,^{\circ}C$ , $t = 15\,min$ , $T_{s} = 50\,^{\circ}C$ and $T(15) = 60\,^{\circ}C$ , then the cooling rate of the substance is:

$60 = 50 + (80 - 50)\cdot e^{-15\cdot k}$

$\frac{60-50}{80-50}= e^{-15\cdot k}$

$\frac{1}{3} = e^{-15\cdot k}$

$k = -\frac{1}{15}\cdot \ln \frac{1}{3}$

$k \approx 0.0732$

The cooling rate of the substance is approximately 0.0732.

Which method of analysis does not classify variables as dependent or independent.

Olin [163]

The method of analysis does not classify variables as dependent or independent is cluster analysis.

Cluster analysis is a method that is used to process data in statistics. In cluster analysis, data is classified into groups based on similar characteristics the data share. For example, if cluster analysis is used to group students, students may be divided into clusters based on their gender or class.

An independent variable is the variable that is manipulated by the researcher. It is the variable that is tested to determine its effect on the dependent variable.

The dependent variable is the variable that is being measured in an experiment.
