Do the Neanderthal burials that have been discovered indicate a pre-human religion?
One of Einstein's great insights was to realize that matter and
energy are really different forms of the same thing.
_ _____ (Q) Matter can be turned into energy, and energy
into matter.
_ _____ (R) Einstein's formula tells us the amount of energy this
mass would be equivalent to, if it were all suddenly turned into energy.

Do the Neanderthal burials that have been discovered indicate a pre-human religion?
______ (Q) One Neanderthal was found lying on his right
side with his head resting on his folded hands at a burial site in Le Moustier,
France.
______ (R) There have been many Neanderthal burial sites found
across the world and it has been an accepted fact that Neanderthals buried
their dead.
______ (S) Such a position hints to some that the Neanderthals
were concerned with his comfort in the afterlife; Yoel Rak, a paleoanthropologist
stated, “I doubt they were buried just because they smelled.”
______ (T) On the other hand, many people believe that they buried
their dead because they had religious beliefs.
______ (U) However, some people believe that they buried their dead
just because they didn’t want animals to eat the carcass or so that they did
not have to view the decaying body.
There is no effective vaccine against malaria.
______ (Q) This includes the use of insecticide-treated mosquito
netting and spraying indoor walls with insecticide.
______ (R) Explain to your doctor exactly where you're going: the
drugs you're prescribed depend on the level of drug resistance within your area
of travel.
______ (S) Two or three months before traveling to an area where
malaria is prevalent, talk to your doctor or a tropical disease specialist or
visit a travel health clinic to obtain the necessary medications to prevent
malaria and to receive travel-related vaccines and information.
______ (T) Beyond the physical means of prevention, most drugs
used to treat malaria are also used to prevent it.
______ (U) In countries where the disease is endemic,
prevention involves keeping mosquitoes away from humans.
Worker bees occasionally kill their queen.
______ (Q) Generally, it has been thought that bees
"balled" strange or introduced queens because the foreign queens did
not have the proper "colony" odor.
______ (R) To do this, 15 or 20 worker bees collect about her in a
tight ball until she starves.
______ (S) More frequently, they will kill a newly introduced or
virgin queen.
______ (T) Even if the ball is broken up, the queen seldom
survives and the stimulus is powerful enough that the bees taking part in the
queen balling are sometimes subsequently balled by other bees.
______ (U) The reason for balling is probably more complicated
that that, because bees occasionally will ball their own queen.
______ (S) This is an incredible amount of energy because one
Joule is about the energy released when you drop a textbook to the floor: so
the amount of energy in 30 grams of hydrogen atoms is equivalent to burning
hundreds of thousands of gallons of gasoline!
______ (T) It says that to find the energy, you multiply the mass
by the square of the speed of light, this number being 300,000,000 meters per
second (a very large number): 0.111 x 300,000,000 x 300,000,000 =
10,000,000,000,000,000 Joules.
______ (U) For example, consider that in one kilogram of pure
water, the mass of hydrogen atoms amounts to just slightly more than 111 grams,
or 0.111 kg.
On November 3, 1957, the U.S.S.R. stunned the world with a space
sensation - the launch of Sputnik 2 with a live dog on-board.
______
(Q) Recently, several Russian sources revealed that Laika survived in orbit for
four days and then died when the cabin overheated.
______ (R) Years after Sputnik 2 burned up in the atmosphere,
conflicting scenarios of Laika's death were circulating in the West.
______ (S) The Soviet press boasted about the 250-pound object
equipped with a cabin, providing all the necessary life support for a dog named
Laika.
______ (T) But many details of what happened to the
mission have only recently been revealed.
______ (U) However, the Soviets admitted soon after the launch
that the spacecraft would not return, meaning that the animal was doomed from
the start.
