Exactly! The fossil record shows stasis and stability not the 'preexisting spieces. Have you ever thought that the similarity of the genetic code could be because it is a stable, broad gene pool created by one supernatural artist? Not a unstable, often mutating gene pool that is not supported by the fossil record. Sorry, you are working off the theory of inherited characteristics that was disproved before Darwin's time. Darwin even knew that once a parent inherits a charateristic they cannot pass it on. If the parents pierce their ear, does the baby come out with pierced ears... No they dont. Please, I need solid evidence.

My reading indicates that many physicists think that space-time has an actual 'fabric' to it; it is a 'plenum' full of exotic 'things' such as virtual particles, wave fluctuations, and so on. If this is right, then is space-time itself the "ether" that Newton speculated about? If space-time is an actual "thing" unto itself and not mere "nothingness", does that "thing" ever move? Or could it be the one completely motionless thing there is?

Ok so heres the question

"Define in your own words what volume means and how volume differs from area. You should keep your answer general and do no include any formulas."

Thanks a lot!

please keep in mind I am a beginning calculus student. Telling me why limits are important would help too, but I sort of get that stuff, I just don't know why the function sin 1/x limit isn't 0.

Ions are electrically charged particles that are formed when certain compounds are dissolved in water. These solutions will conduct electricity. The Swedish scientist Svante Arrhenius coined the term ion (which means wanderer) to explain why solutions of electrolytes will conduct an electric current. When an electrolyte forms into a solution, it dissolves or dissociates into ions, a process called ionization. If a substance does not ionize, it will not conduct an electric current. Electrolytes include most acids, bases, and salts. Some conductors include hydrogen and sodium chloride, copper sulfate, and potassium nitrate. Substances that are not electrolytes include distilled water, sugar water, and most organic compounds. Which of the following is a nonelectrolyte?

a) HNO 3 (nitric acid)
b) HCL (hydrochloric acid)
c) H 2 SO 4 (sulfuric acid)
d) C 3 H 8 (propane gas)
e) NaCl (table salt)

if somebody could help me answer this question that would be awesome! try to make the answers detailed too so that its easy to understand..
THANKs! =)

Interpret data to determaine the oldest rock red. A sandstone contains a 400-million-year-old fossil. A shale has fossils that are over 500 million years old. A limestone, below the sandstone, contains fossils between 400 million and 500 million years old. Which rock bed is the oldest? Explain.

Scientists performed an experiment to determine whether there is a connection between learning ability and food. They took two groups of 20 mice each, all from the same purebred strain. The mice were deprived of food for 3 days and then given a standard learning session in running through a maze. They were trained by giving them a mild electric shock whenever they took a wrong turn. Immediately after each learning session, one group of mice was fed, but the other was not, A week later, all of the mice were tested to see whether they could still run the maze correctly. The group that had been fed had retained this ability, but the other group had not. The probable reason that the scientists used only mice from the same pure-bred strain is so that:

a)the mice would all be the same size

b)the mice would all be the same color

c)the experiment could be repeated with the same mice

d)genetic differences would not affect the outcome of the test

e)the experiment wouldn't cost

1) Discuss how to find the oldest paper in a stack of papers.

If somebody knows these questions, or at least a few, that would be sooo helpful!
Also, when you answer them, try to make them long answers/
THANKS! = )


2) Explain the concept of relative age.

3) Illustrate a disconformity

4) Describe one way to correlate similar rock layers.

5) Explain the relationship between the concept of relative age and the principle of superposition.
