You observe a tissue under a microscope. there appears to be a lumen on one side of the tissue. lining this lumen, the cells seem to have long, fingerlike projections. beneath the projections, the cells seem to have the shape of shoeboxes and are packed tightly together. what type of tissue are you looking at? a. simple cuboidal epitheliab. simple columnar epitheliac. stratified squamous epitheliad. transitional epithelia

The correct answer is A: Simple cuboidal epithelium.

Explanation:

Simple Cuboidal Epithelium: These epithelia are formed by a single layer of cuboidal cells, that are as tall as they are wide. They have a rounded, central nucleus.  Occasionally these cells present cilia, flagella or microvillus in their apical surface, lining the lumen. Microvillus are fingerlike projections.  This epithelium can be found for example in the proximal convolutes renal tubule.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
