What is an Ethical Guideline in Research?
Ethical guidelines are principles that help researchers conduct their work responsibly and ethically.
What is the Scientific Method?
The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
What are Hypotheses?
Hypotheses are testable predictions about the relationship between two or more variables.
What is a Theory?
A theory is a well-substantiated explanation of an aspect of the natural world that is based on a body of evidence.
What is a Placebo?
A placebo is a substance with no therapeutic effect used as a control in testing new drugs.
What is a Variable?
A variable is any factor, trait, or condition that can exist in differing amounts or types.
What is Bias in Research?
Bias in research refers to systematic errors that can affect the validity of study results.
What is a Double-Blind Experiment?
A double-blind experiment is a study design in which neither the participants nor the researchers know who is receiving a particular treatment.
What is an Operational Definition in Research?
An operational definition specifies the procedures used to measure a variable.
What is the Case Study Method?
The case study method involves an in-depth analysis of a single case or a small number of cases.
What are Surveys used in Research?
Surveys are research methods used to collect data from a predefined group of respondents.
What is Meta-Analysis?

What is the Central Nervous System?
The central nervous system consists of the brain and spinal cord.
What is the Autonomic Nervous System?
The autonomic nervous system controls involuntary bodily functions.
What is the Sympathetic Nervous System?
The sympathetic nervous system prepares the body for stressful or emergency situations.
What is the Somatic Nervous System?
The somatic nervous system controls voluntary movements and transmits sensory information.
What is the Peripheral Nervous System?
The peripheral nervous system includes all the nerves outside the central nervous system.
What are Motor Neurons?
Motor neurons are responsible for carrying signals from the central nervous system to muscles.
What are Glial Cells?
Glial cells support and protect neurons in the nervous system.
What are Dendrites?
Dendrites are the branched extensions of a neuron that receive signals from other neurons.
