The slide image shows transitional epithelium through a transverse section of a human bladder wall. what is the function of the tissue indicated by the arrow?

protection of the inner lining of the bladder
contraction of the bladder
structural support of the bladder
nerve impulse conductor for bladder

Ans.

Inner lining of urinary bladder is covered with transitional epithelial tissue, which provides protection to the tissues beneath this layer from alkaline or acidic urine.

Along with protection, epithelial tissue also has ability to stretch significantly. This property of epithelial tissue helps the bladder to accommodate large amount of urine.

Thus, the 'first option' is the correct answer.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
