<h3><u>Answer;</u></h3>
Morphology
The taxon species may be defined by <em><u>reproductive isolation and morphology </u></em>
<h3><u>Explanation;</u></h3>
- <em><u>A taxon is a group of one or more populations of an organism. </u></em>
- <em><u>Morphology is the form or the appearance of a particular organism, </u></em>while <u><em>reproductive isolation is the separation of organisms by some type of barrier.</em></u>
- <em><u>Reproductive isolation is a type of mechanisms that prevent two or more organisms or populations from exchanging genes through reproduction. </u></em>This occurs when two organisms or species are separated for too long such that they can no longer reproduce with each other due to different adaptation and changes in the environment.
- <u><em>Morphology and reproduction isolation may be defining characteristics of taxon of species.</em></u>

The two main variables in an experiment are the independent and dependent variable.
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.
A dependent variable is the variable being tested and measured in a scientific experiment.
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.
For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source) would be the dependent variable.
When results are plotted in graphs, the convention is to use the independent variable as the x-axis and the dependent variable as the y-axis.
To ensure that any bacteria in the urine specimen are from the urine and not from the patient's skin, the nurse's hands, or the environment, the nurse will employ sterile technique to collect a urine specimen from an indwelling urinary catheter.
<h3>
What are Indwelling urinary catheters? </h3>
A tube is placed in the bladder using aseptic approach during indwelling urinary catheterization.
Patients undergo the procedure for many different reasons, such as: Managing acute and chronic urinary retention; Accurately measuring urine output in critically ill patients; Bypassing an obstruction, such as an enlarged prostate gland in men; Administering medications directly into the bladder; and Conducting bladder function tests.
When all other conservative management techniques have been tried and failed, catheters can also be utilized to control incontinence and preserve skin integrity.
Numerous problems are linked to indwelling urinary catheterization, such as catheter-associated urinary tract infection (CAUTI), tissue injury, bypassing, and obstruction.
