Answer:
Prokaryotic are organisms that consist of a single prokaryotic cells and Eukaryotic cell are found in plants, animals, fungi and protists.
Explanation:
they are range from 10-100 micrometre in diameter, and their DNA is contained within a membrane-bound nucleus.
Answer:
Stimuli must be sensed in order to respond.
Explanation:
Classical conditioning can be defined as a learning process which typically involves repeatedly pairing two stimuli: conditioned stimulus and unconditioned stimulus.
Simply stated, it is a learning procedure that helps us to understand when a neutral stimulus is paired with a conditioned response.
An example is the process of salivating in response to the aroma of a meal being prepared in the kitchen.
Also, operant conditioning can be defined as an associative learning process which involves reinforcing the strength of a behavior.
Stimulus in biology 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.
Hence, the senses are necessary for behavior because stimuli must be sensed in order to respond.

What type of scientist is most likely to study the cooling of lava after a volcanic eruption?
Geologists are the scientists that is likely to study the cooling of lava after a volcanic eruption. Geologists are scientists that study about Earth science; everything relate to Earth.` If we are being to precise, the scientists who study related volcanoes are called vulcanologist. They study about the development and eruption of earth.
Hope I helped :D
