The egg shell consists of three basic layers: a lipoidal inner layer, a chitinous middle layer, and outer layer of protein.

The actual egg has 8 different parts: Shell, Yolk, Vitelline Membrane, Air Cell, Chalazae, Albumen, Inner Membrane and Outer Membrane. Each part of the egg serves a different purpose. Shell: This is the outer layer of the egg which is made up of Calcium Carbonate.

​​The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly com​posed of basalt.

The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C).

The medical community generally defines a fever as a body temperature above 100.4 degrees Fahrenheit. A body temp between 100.4 and 102.2 degree is usually considered a low-grade fever.

Normal body temperature ranges from 97.5°F to 99.5°F (36.4°C to 37.4°C). It tends to be lower in the morning and higher in the evening. Most healthcare providers consider a fever to be 100.4°F (38°C) or higher. A person with a temperature of 99.6°F to 100.3°F has a low-grade fever.

An adult probably has a fever when the temperature is above 99°F to 99.5°F (37.2°C to 37.5°C), depending on the time of day.

“The CDC’s recommendation is to stay home until you are fever free for 24 hours without the help of a fever reducer.” Because you are still contagious after the fever subsides, Pittman emphasizes the importance of handwashing and taking extra care to contain your cough or sneeze.

Other symptoms that may occur along with low-grade fever Decreased appetite. Ear pulling in children. Easy bleeding or bruising. Feeling hot without sweating.

All employees should stay home if they are sick until at least 24 hours after their fever* (temperature of 100 degrees Fahrenheit or 37.8 degrees Celsius or higher) is gone. Temperature should be measured without the use of fever-reducing medicines (medicines that contains ibuprofen or acetaminophen).

One of the most common causes of a continuous low-grade fever is respiratory infections like cold or the flu. In such cases body naturally elevates its temperature to combat off the infection causing agents (bacteria or viruses). Cold or the flu are caused by viruses and with cold, fever lasts for a few days.
