What are the skin functions?
Functions of the skin
- Provides a protective barrier against mechanical, thermal and physical injury and hazardous substances.
- Prevents loss of moisture.
- Reduces harmful effects of UV radiation.
- Acts as a sensory organ (touch, detects temperature).
- Helps regulate temperature.
- An immune organ to detect infections etc.
How does the structure of the skin relate to its main functions?
The skin consists of two layers: the epidermis and the dermis. Beneath the dermis lies the hypodermis or subcutaneous fatty tissue. The skin has three main functions: protection, regulation and sensation. Wounding affects all the functions of the skin.
What are the different roles of the skin in homeostasis?
Skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. When body temperature falls, the sweat glands constrict and sweat production decreases.

What is the strongest material on earth 2020?
(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.

Is Platinum better than gold?
Is Platinum Better than Gold? No, platinum is not better than gold, as platinum looks nearly identical to white gold but costs significantly more. Both 14K and 18K white gold are durable enough for everyday wear, so platinum jewelry isn’t necessary. Platinum also scratches more easily and requires more maintenance.
Which gold is the strongest?
24K
Which is stronger diamond or platinum?
Platinum is not a hard metal. It is 4 – 4.5 on the MOHs scale of hardness. This means it can be scratched by anything harder than it is. Diamond is ten on the MOHs scale and can easily scratch platinum.
What is the hardest rock in the world?
Diamond is the hardest known mineral, Mohs’ 10.
What is the most strongest rock in the world?
The strongest rock in the world is diabase, followed closely by other fine-grained igneous rocks and quartzite. Diabase is strongest in compression, tension, and shear stress. If mineral hardness is the determining factor of strength then diamond is technically the strongest rock in the world.
