How do epithelial cells adapt to remove dirt?
the goblet cells in the bronchioles produce a mucus which traps foreign substances in the airway such as pollen, pathogens and dust particles. The cilia of the ciliated cells will then waft the mucus and the trapped particles up to the larynx where it can be swallowed and the pathogens can be destroyed by the stomach acid. The cilia can waft due to the energy produced in the cells (in the form of ATP) by the mitochondria.
Is dirt homogeneous mixture or a heterogeneous?
yes dirt is a heterogeneous mixture
How much dirt is in a hole if the hole is 10 ft in width 5 ft long and 20 ft deep?
Theoretically, none. The amount of dirt excavated to create such a hole would be 1 cubic metre. However, excavated dirt (depending on the nature of the dirt) can increase in mass by up to a third the original size. That is why when you dig a big hole then fill it in (getting all the dirt back) the hole is raised on top not flat.
Does soil particles have a positive or negative charge?
Our Ag class did an experiment that involved the positive and negative charges of soil particles. We used a battery, two copper rods, two copper wires with alligator clamps on each end and a jar of washed down dirt or mud if you will. We clamped one end of the wire to the battery and one end on the copper rod for bothe the positive and negative charges. We stuck the rods in the dirt. Most of the dirt clinged to the positive rod therefore, soil has a negstive charge (for the most part.
How do you decide which number is greater when one number is negative and one number is positive?
ANY positive number is greater than any negative number. Imagine you are digging a hole, and piling up the dirt you remove from the hole. The hole represents negative numbers- it goes lower than the surface. The piled up dirt represents positive numbers- it is higher than the surface. The surface is zero- neither positive or negative.

Can you find a reason why negative numbers were invented?
You need to have numbers that represent the idea of taking something away. If I pile up some dirt and consider the ground as level zero. Then the height of my hill is a positive number. If I dig a ditch, I must take dirt away. If the earth again is ground zero, the depth of my ditch can be given as a negative number. If my hill is 101 feet high, I use 101, but if it is 101 feet deep, I use -101. Other examples are owing money as a negative and earning as a positive. RAWR
