Epinephrine in animals and auxin in plants act as hormones
that triggers specific cellular responses that vary among different tissues of
the organism. The biosynthesis of epinephrine involves breaking just one
carbon-carbon bond in the amino acid tyrosine, Synthesizing epinephrine
requires breaking the bond between the carboxyl group (COOH) and the α-carbon
in tyrosine.
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.
Answer:
According to the law of conservation of matter, matter is never created or destroyed but it can change from one form to another. Most of the biomass in a food web gets converted at each trophic level and it no longer remains apart of the food web. Most of the biomass is released into the atmosphere in the form of heat and hence cannot be transferred to the other trophic level. Also, matter is used up by the organism itself and converted into different forms. Most of the matter might get accumulated in the soil when the organisms of a trophic level die.
