Researchers suggests that we can avoid self-confirming diagnoses by all the given options.
<h3><u>Explanation:</u></h3>
Self confirming of diagnosis of a disease is actually good for a skilled person, but for general persons, it can be very dangerous and can cause severe outcomes. Different diseases have similar symptoms, but the outcomes are very different.
Some insignificant diseases like indigestion, acidity do have symptoms of loose motion, along with severe diseases like cholera, typhoid, dysentery, and acute arsenic poisoning. So its very necessary for checking the actual cause of the disease by differential tests as well as carefully classifying the symptoms by a professional doctor.
A dominant allele hides a recessive allele and determines the organism's appearance
The presence of palpable lymph nodes.
Lymph nodes are relatively large in children, and the supperficial ones often are palpable even when the child is healthy.
The changing quantities in an experiment are called variables. A variable refers to any trait, factor, or a condition, which can prevail in distinct amounts or kinds. An experiment generally exhibits three kinds of variables: independent, dependent, and controlled.
The independent variable refers to the one, which is modified. On the other hand, the dependent variable is implied to observe that how it reacts with the change made to the independent variable. The controlled variables refer to the quantities, which one wants to remain constant.
In the given case, that is, heating a cup of water to witness that whether the sugar will get more easily dissolve. In this, the independent variable refers to the temperature of the water determined in degrees Centigrade. The dependent variable refers to the amount of sugar, which dissolves completely measured in grams.
In this, the controlled variables are stirring and type of sugar. As more stirring might elevate the amount of sugar that dissolves, and different kind of sugars might dissolve in distinct concentrations. So, in order to make sure a fair test, there is a need to keep these variables similar for each cup of water.
