Every cell of the organism has the same DNA sequence and same genes. However, not all genes are expressed in every single cell at the same time. Only those genes necessary for a specialised function of a specialised cell are expressed in the specialised cell. For example, skin cells have some different proteins than nerve cells. Genes responsible for those "skin proteins" are activated in skin cells and are turned off in nerve cells.

Homeostasis is defined as a state in which the conditions of an organism's internal environment are maintained within tolerable
Kaylis [27]
There are many cases of homeostasis mechanism. In this mechanism, there will be a receptor that will catch a condition. After that, an order will be sent to various place depend on the condition.
One of them is temperature control which was done by shivering or sweating. When your body temperature is too high, the thermoreceptor will detect it and then the brain will send the order to the body sweat glands. Sweat on body surface will evaporate and reduce body temperature.
When the temperature is too low, the brain will tell the muscle to shiver so you can produce heat.

Other than temperature, homeostasis also control blood pressure, or many chemical level(oxygen, glucose).

A clay plate has a volume of 30.0cubic centimeters and a mass of 59.1grams. Calculate its density.
Nataly_w [17]

The density of the clay plate is  1970 kg m⁻³

the problem we are dealing with is related to density, which is the mass of a unit volume of a material substance. The formula for calculating density is d = M/V, where d is density, M is mass, and V is volume. Since we are provided with the volume of the clay plate which is 30.0cubic centimeters and the mass of the plate which is 59.1grams

so,V= 30 cm⁻³=3x 10-5 m and  M=  59.1grams= 0.0591 kg

Therefore, the density of the plate is:  M/V

=>d = 1970 kg m⁻³
