The correct answer is Economic cycle.
The natural fluctuation in economy between the period expansion (economy growth) and contraction (recession) is known as the economic cycle.
The normal growth and downturn in the economy is the basic definition of Economic cycle.
During the time of expansion the investors seek to purchase companies and shares and during the time of contraction the investors look to invest and purchase the companies such as utilities and healthcare.
The correct answer is Economic cycle.

A) by blocking a receptor site and preventing the neurotransmitter from acting
B) by mimicking a particular neurotransmitter and producing the same effect
C) by increasing the length of time a neurotransmitter remains in the synaptic gap, strengthening its effects

The answer is
D. by bonding with the neurotransmitter and changing its molecular weight and shape
b)The experiment will lack a purpose.
c)The experiment will not be repeatable.
d)The experiment will not have variables.
Answer;
The experiment would lack a control group
Explanation;
-An experiment deliberately imposes a treatment on a group of objects or subjects in the interest of observing the response.
-Experimental design involves taking time and effort to organize the experiment properly to ensure that the right type of data, and enough of it, is available to answer the questions of interest as clearly and efficiently as possible.
-A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
