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.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
