Which sensory system(s) have receptors which die after awhile because it/they have direct exposure to the environment?\?
Anika [276]
The OLFACTORY AND THE GUSTATORY SYSTEMS have receptors which die out after sometimes because of direct exposure to the environment.
The olfactory system has to do with the perception of smell while the gustatory system has to do with taste stimuli. For these two basic sense organs, their perception rate is always highest when they are newly exposed to a stimuli, after continuous exposure to the stimuli their receptors die out.

Answer:

The correct answer is A: Simple cuboidal epithelium.

Simple Cuboidal Epithelium: These epithelia are formed by a single layer of cuboidal cells, that are <em>as </em>tall as they are wide. They have a rounded, central nucleus.  Occasionally these cells present cilia, flagella or <em>microvillus</em> in their apical surface, lining the lumen.

You are served dessert at a restaurant. You want to know what % of the calories in the dessert are from fat. The menu states tha
jasenka [17]

Answer:

39.82 %

Explanation:

Proteins and carbohydrates provide 4 calories per gram. On the other hand, fats provide 9 calories.

We can first calculate the calories of protein + carbohydrates:

       (30g + 4g) x 4 = 136 calories

And we must calculate the calories provided by fat:

        10g x 9 = 90 calories

Now to get the percentage we must see how many calories the dessert has in total:

          136 + 90 = 226 cal

This represents 100% of calories. And now we need to find out how much 90 calories are from the total.

           226 cal -----> 100%

             90 cal ------> X

       (90 x 100) / 226 = 39.82 %
