</span>
Sarcoidosis is a disease that caused by the appearance of multiple gr<span>anulomas, l</span>ump that made of inflammatory cells. Chest x-ray should show these lump easily, especially in the lungs because it is filled with air.

Being dipole allows water molecules to do some pretty spectacular things. Describe at least one property the occurs because of t
Roman55 [17]

The polarity of water enables it to serve as a solvent for polar substances.

A polar substance is a substance that has a positive end and a negative end. Water itself is a polar substance and this polarity enables it to dissolve polar substances.

For instance, HCl dissolves in water because it is polar. The positive end of the dipole in HCl attaches to the negative end of the dipole in water and the negative end of the dipole in HCl attaches to the positive end of the dipole in water.

This dipole - dipole interaction accounts for the dissolution of HCl in water.

Also, ion - dipole interaction accounts for the dissolution of ionic substances such as NaCl in water.

Pheromones used in reproduction are not likely to be found in organisms that only reproduce?
monitta

Pheromones used in reproduction are not likely to be found in organisms that only reproduce asexually.

The chemicals called pheromones are used to communicate between members of the same species and cause the recipient to react physically or behaviorally. Pheromones are a subset of organisms' larger class of chemicals to communicate, known as semiochemicals, from the Greek <em>semeon</em>, meaning signal or mark.

Animals communicate chemically constantly, with pheromones mediating more interactions than any other type of signal. The majority of pheromone research has been conducted on insects, particularly species that are considered pests.

For these, using pheromones that alter their behaviour in various ways might be employed for population control, pest management, or monitoring.
