What causes an organism to react?

Anything that causes an organism to react or respond is called a stimulus (plural: stimuli). Stimuli can be external (outside the organism) or internal (inside the organism).

What is a change that causes an organism to react called?

A change in an organism's surroundings that causes the organism to react is called a stimulus (plural stimuli). An organism reacts to a stimulus with a response- an action or change in behavior. ... Another characteristic of organisms is the ability to reproduce, or produce offspring that are similar to the parents.

What term describes what an organism responds to?

Stimulus Definition. Science of Stimulus & Response. Types of Stimuli. External stimulus. Internal stimulus.

What describes an organism responding to a stimulus?

What is a response? Response: how the organism reacts to a stimulus and results in a change in behavior. (It is a fancy way of saying “effect”.) Example: Getting a drink when you are thirsty.

How do organisms react to outside factors?

Organisms respond to external stimuli to maintain homeostasis. Every organism has its own range of tolerance. When an environmental condition (such as temperature) goes above or below an organism's optimal range, the organism experiences stress and responds to the stimulus.

What term describes a change in an organism's outside environment?

Evolution describes changes in inherited traits of populations through successive generations. ... So it is with ecology: Evolution provides a canon by which we may better understand the interactions of organisms with their environments.

What is stimuli answer?

In physiology, a stimulus is a detectable change in the physical or chemical structure of an organism's internal or external environment. ... Although stimuli commonly cause the body to respond, it is the CNS that finally determines whether a signal causes a reaction or not.

What is the scientific definition of response?

an answer or reply, as in words or in some action. Biology. any behavior of a living organism that results from an external or internal stimulus.

What is internal stimulus?

Internal Stimulus.  An Internal Stimulus is a stimulus that comes from. inside an organism.  Examples:  You have an infection so you run a fever.

What is stimulus and response in biology?

A Stimulus is any change either internal or external which leads to a response. This could be a noise, smell or the changes in blood sugar level. A Receptor is a specialized cell which can sense the stimulus. ... The Response is what happens when the organism reacts to the stimulus.

What is an example of homeostasis?

The maintenance of healthy blood pressure is an example of homeostasis. ... If blood pressure is too high, the heart should slow down; if it is too low, the heart should speed up. More than half of a human's body weight percentage is water, and maintaining the correct balance of water is an example of homeostasis.

Which of the following is a characteristic of living organisms?

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

What is the scientific term of a living thing?

Organism. n., plural: organisms. [ˈɔɹ.ɡən.ɪ.zəm] Biology definition of organism: a living thing that has an organized structure, can react to stimuli, reproduce, grow, adapt, and maintain homeostasis.

What is an example of adaptation?

Adaptation is the evolutionary process where an organism becomes better suited to its habitat. ... An example is the adaptation of horses' teeth to grinding grass. Grass is their usual food; it wears the teeth down, but horses' teeth continue to grow during life.

What is stimulus class 9?

A stimulus is a change in the external or internal environment which brings about a physiological response i.e when applied on any sensory receptor it elicits action or response. A stimulus may be internal stimuli (such as changes in blood pressure) or external stimuli (such as touch, sound, smell, taste, vision, etc.)

What are the 3 types of stimuli?

excited by three types of stimuli—mechanical, thermal, and chemical; some endings respond primarily to one type of stimulation, whereas other endings can detect all types.

What is class 10 stimulus?

What is a Stimulus? The changes in the environmental conditions to which the organisms respond are known as stimuli. Every living organism responds when an external stimulus acts on it. When various organs work together in a systematic manner to produce a response to the stimulus, it is called coordination.
