Answer:
In studies about new medicines, researchers usually give one group of patients the medicine that is designed to treat an illness. They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.
In medical experiments, which group receives placebos?
the experimental group
the control group
both the experimental and control groups
neither the experimental nor control group
Explanation:
Answer:
There is no difference between ‘’ and “” string type in python. Both are used to hold the string or sequence of character in the python. triple """ """ can also use for the same.
Example:
str1 = "aeiou"
str2 = 'aeiou'
str3 =""" hello"""
print(type(str1), type(str2),type(str3))
<class 'str'> <class 'str'> <class 'str'>
Here all are used to hold string or sequence of character.
Answer:
zeroIt(&x);
Explanation:
The statement that sets the value stored in x to zero by invoking the function zerolt is given below
zeroIt(&x);
The zeroIt function is also given below for better understanding.
void zeroIt(int *x) {
*x = 0;
}
As seen, the function takes an argument with integer variable type, which is a pointer, denoted by the asterisk symbol (*x).
The ampersan sign (&x) is used to access the variable whose value can then be stored.
