What prevents the sun's ultraviolet rays from penetrating the interior of the body?
Ultraviolet rays are very short wavelength waves above even the blue waves in the electromagnetic spectrum. They are responsible for sunburns on the skin, but are stopped by the skin. When compared with the longer infrared (heat)waves below the red waves in the same spectrum which can easily penetrate the skin and physically cook the entire body given sufficient time.

UV light, when the body is over-exposed, can cause skin cancer, premature skin aging, eye damage and problems with the immune system. That is why it is important to apply sunscreen when you are out for a sun tan. It can also be helpful to have a UV monitor to measure the current intensity of the UV radiation from the sun as it can then let you know how long you should stay unsheltered in the sun.
How the body reacts to hot and cold environment?
In hot environments, the body reacts by increasing blood flow to the skin and activating sweat glands to promote cooling through evaporation. This process helps regulate body temperature and prevents overheating. Conversely, in cold environments, the body conserves heat by constricting blood vessels, reducing blood flow to the skin, and initiating shivering to generate warmth through muscle activity. These physiological responses help maintain a stable internal temperature despite external conditions.

Why would it be wrong to say homeostasis prevents internal change?
dude homeostasis is the process by which the internal environment of ur body stays constant for example in warm blooded animals when the body temp rises u start sweating and ur arterioles near the skin dilate so in this example homeostasis has occurred and there has been an internal change(dilation of the arterioles and production of swear) therefore homeostasis doesn't prevent internal change
