a. When sensory information is detected by a sensory receptor, sensation has occurred. TRUE
For example, light that enters the eye causes chemical changes in cells that line the back of the eye. These cells relay messages, in the form of action potentials, to the central nervous system.
b. All sensory systems have absolute and difference thresholds. FALSE
Absolute threshold refers to the minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time.
c. Sensory receptors are specialized neurons that respond to specific stimuli. TRUE
d. Sensation refers to the way sensory information is organized, interpreted, and consciously experienced. TRUE
Sensation is input about the physical world obtained by our sensory receptors, and perception is the process by which the brain selects, organizes, and interprets these sensations.
A common advantage which can be often observed in group conflict would be that we can see the members' ideas, oppinions stances and even suggestions. All of these are important when we're working in a group and are trying to find a solution to a complex problem which is related to everybody.

The plates holding cells together in tissues are called desmosomes. Desmosomes are the tissue basement. They hold the cells together. So the tissues retain in a definite shape. These are the intermediate filaments and make a net-like structure. These are made up of keratins. It is a structural protein found exclusively in nails and hairs. The desmosomes are 3 types- spot desmosomes, belt desmosomes, and hemidesmosomes. Desmosomes are the connection between 2 cells.
