Rays

Stingrays are typically docile animals. They spend most of their time resting on the ocean floor and can be curious if approached slowly. However, they can use their venomous barb for defense if they feel threatened.

Stingrays are nocturnal animals that mean they eat at nighttime.

Yes they do!
Yes, they have a backbone.

string rays do not lay eggs they have it on there body and it hatches it out alive

sting rays are gray but can be brown. they will not bight but will sting. on the bottom of the sting ray, it is white.

Hammerhead sharks are the most common predator of stingrays.

they use their sting tail to protect themselves

Yes

No. The manta ray does not have a barb of any type. They have large eyes that are used for searching out for predators.

Stingrays have either one or two young at a time. They usually do not breed more than one per year and they give birth to live young.

There are over 200 species of stingrays worldwide, belonging to several different genera. Some popular species include the southern stingray, spotted eagle ray, and manta ray.

Rays are native to the Atlantic, Pacific, and Indian Oceans. They can be found in tropical to cold temperate climates, living between 8 m and more than 3000 m under the surface.

They have moved from Sea water to fresh water.About 50 ray species throughout the world regularly venture into fresh water. More than two dozen species are capable of surviving their life cycles in fresh water. At the extreme, several ray species in the Amazon River Basin have become so rigidly adapted to river life that they cannot survive salt water

Stingrays come from the ocean. Stingrays are found in parts of the ocean that are warmer and more shallow. A stingray has a tail that stuns its prey with an electric shock.

it is called 'a fever'

Manta rays are huge flat fish that are related to sharks and stingrays. Because of their size, the only predators they have are sharks, killer whales, and humans.

Lead is a very dense substance and so can absorb most of the radiation which hits it, this means that less radiation is able to get to the part of your body which is not needing an x-ray.

So, in short, lead is used to protect parts of the body from unnecessary exposure to radiation. This is good because radiation like x-rays can cause mutagens which can increase the rate of mutations in genes and DNA (sometimes causing Downs Syndrome etc.)

Not enough information. Red eyes can be caused by several things, including allergies and infections.

X rays and gamma rays are both in the electromagnetic spectrum, gamma rays can come from nuclear bombs (which can pass through metals and concrete). X rays are used in many places, in the hospital, the air port, and many more, I don't really know what their source is I'll have to check in my science encyclopedia.

Because Bones are more DENSE than Soft tissues/Flesh&they BLOCK X-Rays,while Soft tissues block minimal X-Rays-So,Bony Structures are seen as shadows on Plain Films,while Soft tissues are Unclear.

Gamma rays are electromagnetic radiation and have very high penetration power. Gamma rays are similar to UV rays and x-rays in the sense that all of them are forms of electromagnetic radiations.
