Deserts

Your question makes no sense. Rainfall is not measured in percent but in inches or millimeters. I desert is defined as a region that receives less than 10 inches (260 mm) of rainfall per year on average.

Deserts generally do not have sufficient water to support many trees.

These states have considerable desert land:

Arizona

Nevada

New Mexico

Utah

Colorado

These states have some desert land:

California

Texas

the deathstalker scorpion lives in the sahara desert in africa.

Deserts are needed because they provide habitat to a series of very unique animals and plant life. The Joshua tree for example is one very special cactus only found in the desert in Arizona.

In some deserts, such as the Mojave and Sahara Deserts, the temperature may approach 140 degrees F on a hot, summer day.

The only similarity is that both receive limited precipitation. The Sahara is a huge, hot desert located in northern Africa. The Ladakh is a cold, high mountain plateau desert in northern India,

Deserts are naturally in a perpetual state of drought.

Counting all the cacti in a desert is a virtual impossibility.

There is no minimum amount as some deserts go centuries with no measurable rainfall. The maximum is 10 inches (250 mm). More than 10 inches average in a year moves the region into the steppe climate.

The Rub al-Khali (aka 'the Empty Quarter') is in Saudi Arabia.

less than 250 millimeters (10 in) per year
10 inches per year

I have worked with native wildlife of the Chihuahuan Desert for many years and I can guarantee that fleas survive in the desert.

'Live forever' means immortal, which means you can do anything!

Life will be the best!

hot desert is high in temperature and low in water this means their is little or not at all any vegetation that happends in the hot dessert because if their is no water photosynthesis can not take place

Camels live without water for up to two weeks.

The Arabian Peninsula is almost entirely desert.

Far west Texas falls in the Chihuahuan Desert and receives less than 10 inches (250 mm) of rainfall per year on average.

If you are referring to the number of deserts, that would be Australia which as 10 distinct deserts. . For a list of these Australian click on this link.

its called Rub al khali and its in Saudi Arabia

If we assume for simplicity that all sand grains are the same size and spherical there are about 1 million three hundred thousand grains of sand in a given meter of desert. Instead of the average desert I said the Sahara. The Sahara has a area of around 9 million kilometers. We can do 9 million times 1k to get the number of meters in the desert. So I did 1,300,000 * (9,000,0001,000) and that gave 1.1710^18. That is around 1,170,000,000,000,000,000 grains of sand. Assuming I didn't look over something, although I probably did, that should be the number of sand grains in the Sahara. But if you want to choose any desert you can just change the 9,000,000*1000 to correctly match the information of the desert. Also keep in mind that this does not account for the depth of the sands but only accounts for surface and near surface grains.

The bacteria that can be found in the desert is very different than normal bacteria, because it has adapted to the harsh heat, sun, and little shade or water. One unique type of bacteria that can be found in the desert is called "desert varnish" and is a type of fungus.
