Answer: Variations are the differences in individuals or their traits present within the organisms of a species which are caused by environmental and inherited factors. The inherited variation is caused due to genetic factors or information carried from the parents. Variation caused due to environmental factors includes climate, lifestyle, diet, culture etc.

Darwin explained the differences in traits on the basis of natural selection. Darwin also believed that variations in traits resulted due to inheritance and environmental factors. Darwin’s theory of evolution through natural selection suggests that individuals vary in their ability for survival as well as for their reproduction. The individuals with most favorable traits survive longer and have more number of offspring.

In order to perceive forms and patterns from incoming stimuli, individuals utilize____.
4vir4ik [10]

Group of answer choices.

A. feature analysis

B. change blindness

C. selective attention

D. inattentional blindness

Answer:

A. feature analysis

Explanation:

Stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.

In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.

Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.

For example, opening the door of a microwave oven as soon as its timer beeps.

Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.

In order to perceive forms and patterns from incoming stimuli, individuals utilize feature analysis of the signals from the environment.
