Directional selection can be used by artificial means as well. This can be seen is "pure bred" cats, dogs, horses and many others.

What is meant by Directional and Non-Directional Stimuli?

Directional stimuli are environmental stimuli, particularly light and sound, that the direction of which it comes and the direction of the response to the stimulus are of upmost importance. Non-directional stimuli are those where receptors do not detect the direction from which they come. Chemical stimuli are usually not directional.


Explandiate the following tropic movement chemotropismgalvanotropismand trantotropism?

Chemotropism is the directional growth or movement of an organism in response to chemical stimuli, guiding its movement towards or away from the source. Galvanotropism is the directional growth or movement of an organism in response to electrical stimuli. Thigmotropism is the directional growth or movement of an organism in response to physical touch or contact with a solid surface.


Define tropism and give two examples?

Tropism is the directional growth response of a plant in response to a stimulus. Two examples of tropism are phototropism, where plants grow towards light, and gravitropism, where plants grow in response to gravity.


What is the answer to growth in response to a stimulus?

The growth in response to a stimulus is called tropism. Tropisms are directional growth responses exhibited by plants or organisms in response to specific environmental cues such as light, gravity, or touch. These growth responses help the organism to adapt and survive in its environment.


What is the difference between stimulus and tropism?

A stimulus is any change in the environment that elicits a response from an organism. Tropism, on the other hand, is a directional growth response of a plant to a stimulus, such as light or gravity. In other words, tropism is a specific type of response exhibited by plants in reaction to environmental stimuli.

What is agonsit?

An agonist is a chemical that binds to a receptor of a cell and triggers a response by the cell. An agonist often mimics the action of a naturally occurring substance.


What is a directional plant response?

A directional plant response, also known as tropism, is the growth or movement of a plant in response to a directional stimulus, such as light, gravity, or touch. For example, phototropism is when a plant grows towards a light source. These responses allow plants to adjust their growth and development to optimize their chances of survival and reproduction.

Can marsupials get rabies?

Not in Australia. There is no rabies in Australia.


Distinguish nastic non directional movements from tropic responses?

Nastic movements are non-directional responses to external stimuli, triggered by changes in environmental factors like temperature or humidity. These movements are not correlated with the direction of the stimulus. Tropic responses, on the other hand, involve directional growth or movement of an organism in response to a stimulus, such as phototropism (response to light) or gravitropism (response to gravity).


What causes thigmotropism?

It is the directional response of a plant organ to physical contact with a solid object.


What is a naturally occurring reaction to a particular stimulus?

The reaction to a stimulus is called a response. An intensified stimulus usually evokes a more intense response. Of course the type of response to a stimulus depends on the nature of the stimulus. Scream at someone and they likely will feel verbally attacked. The screaming is the stimulus, feeling attacked is the response.


Random movement in response to a stimulus is called?

Random movement in response to a stimulus is called kinesis. Kinesis is a non-directional response where the organism changes its rate of movement in response to a stimulus, but not the direction.


How can you build pressure controller by fast response directional valves?

Super glue and duct tape.


What is a stimulus which naturally elicits a response called?

A stimulus which naturally elicits a response is called an unconditioned stimulus. This type of stimulus triggers a reflexive or innate response without prior learning.


What are the causes of non-sampling errors?

non response, in accurate response and selection bias
