placebo, a substance with no significant effect on a subject’s physiology but is given to a control group that thinks they are being given the treatment.

What is a structure that carries out a response to a stimulus called?
Organelles. A structure that carries out the body’s ultimate response to a stimulus is called an. Effector.
What are the simplest body structures considered alive?
What is a cell? No cells– no life! The simplest structure considered to be alive.
Which branch of medicine examines tissues for disease?
Pathology is a branch of medical science that involves the study and diagnosis of disease through the examination of surgically removed organs, tissues (biopsy samples), bodily fluids, and in some cases the whole body (autopsy).
Which term refers to a cell or organ that is specialized to detect a stimulus?
receptor organ. a cell or organ specialized to detect a stimulus.
Which of the following is a process by which an educated guess is capable of being tested?
1) hypothesis an educated guess about a possible solution to a mystery; a prediction or statement that can be tested; A reasonable or educated guess; what a scientist thinks will happen in an experiment.
What term defines a substance that consists of a solute dissolved in a more abundant substance called the solvent?
Solution. solution consists of particles of matter called a solute mixed with a more abundant substance, usually water, called a solvent.
What is the process of transforming a cell with no specialized function into a cell with a specialized function called?
Answer and Explanation: The process of transforming an unspecialized cell into a specialized functional cell is known as differentiation.
What type of equilibrium occurs when there is a set average point and conditions fluctuate around that point?
Homeostasis is a dynamic equilibrium that is maintained in body tissues and organs. It is dynamic because it is constantly adjusting to the changes that the systems encounter. It is in equilibrium because body functions are kept within a normal range, with some fluctuations around a set point for the processes.
How many organ systems are there in the human body?
The nine major organ systems in the human body are the integumentary system, the musculoskeletal system, the respiratory system, the circulatory system, the digestive system, the excretory system, the nervous system, the endocrine system, and the reproductive system.
Which of the following is not an essential part of anatomical position?
Standing erect, face forward and toes pointing forward are all considered anatomical positions. Palms facing backward is not considered an anatomical position.
What is the study of body functions called?
Physiology is the study of how the human body works. It describes the chemistry and physics behind basic body functions, from how molecules behave in cells to how systems of organs work together. It helps us understand what happens in a healthy body in everyday life and what goes wrong when someone gets sick.
What is the smallest unit of an organism that can carry out all the functions of life?
Cells- the smallest unit that can perform all of life processes.
What is a microscopic structure in a cell that carries out individual functions called?
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.
What is the study of the structure or form of the body and its parts?
Anatomy is the study of the body’s structure. It is a branch of science that investigates organs, bones, structures, and cells that exist in animals and people.
What is a cell or organ that is specialized to detect a stimulus called quizlet?
A sensory receptor is any structure specialized to detect a stimulus. Some receptors are simple, bare nerve endings, such as the receptors for heat and pain, whereas others are true sense organs.
Which term refers to the area within which a single sensory neuron is able to detect a stimulus?
Area within which a single sensory neuron is able to detect a stimulus. Which term refers to a local, stimulus-induced change in the membrane potential of a receptor cell? Receptor potential.
How are stimuli received by receptors for touch taste smell sight and sound?
Specialized cells and tissues within these organs receive raw stimuli and translate them into signals the nervous system can use. Nerves relay the signals to the brain, which interprets them as sight (vision), sound (hearing), smell (olfaction), taste (gustation), and touch (tactile perception).
Which term means the study of the molecules and chemical reactions that occur in living cells?
Biochemistry. the study of the molecules and chemical reactions that occur in living cells. Describe a decomposition reaction: breaks down a large molecule into smaller parts.
Which of the steps in the scientific method means an educated guess or a tentative answer to a problem?
A scientific hypothesis is a tentative, testable explanation for a phenomenon in the natural world. It’s the initial building block in the scientific method. Many describe it as an “educated guess” based on prior knowledge and observation.
Which method of reasoning begins with a hypothesis or question and then tries to answer the question?
The inductive approach begins with a set of empirical observations, seeking patterns in those observations, and then theorizing about those patterns. The deductive approach begins with a theory, developing hypotheses from that theory, and then collecting and analyzing data to test those hypotheses.
Which term is used to describe the structure formed by the combining of the enzyme and its specific substrate?
the substrate-binding site of an enzyme is known as the active site. enzyme is a protein that functions as a biological catalyst.
Which term refers to the substance that is dissolved into another substance such as water?
Solute. a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
What is the scientific term for a liquid that dissolves substances?
Solvent – The solvent is the substance that dissolves the other substance.
Which term refers to a molecule cell or organ that carries out a response to a stimulus?
effector. a molecule, cell, or organ that directly carries out a response to a stimulus.
