Science questions for homework (Bio B)?
Is it good for a species to have greater variation than little variation in phenotypes?
Absolute age of a fossil that is one-thirty second (1/32) of the original radioactive Carbon 14 remain. (Hint C-14 is 5770 yrs.) How old is this fossil?
My guess 180.3125
Fossilized colony calculated to be 2.6 billion yrs old using the K-40 method of radioactive dating. (Hint the half life of K-40 is 1.3 billion yrs) How many half live have elapsed?
My guess 3.38
Scientific principle says that scientific phenomenon must be explained using the observable evidence and process and not myth. (i.e The process occurring today are similar to ones that operated in the past.)
a. Evolution
b. Homology
c. Radio Carbon Dating
d. Uniformitarianism
e. none above
True of False Scientist have never found a fossil of another species from the genus Homo.
59 minutes ago - 4 days left to answer.
morphologist determine the relationship between species by
a.amino acid
b. biological structures (anatomy) of living organisms
c.DNA
d. proteins
e. a & b
f. a & b
e. none above
I'm guessing b.

> Absolute age of a fossil that is one-thirty second (1/32) of the original radioactive Carbon 14 remain. (Hint C-14 is 5770 yrs.) How old is this fossil?
It halves every 5770 years. It has to do that 5 times for there to be 1/32 left, so that's 5 x 5770 = 28,850
> Fossilized colony calculated to be 2.6 billion yrs old using the K-40 method of radioactive dating. (Hint the half life of K-40 is 1.3 billion yrs) How many half live have elapsed?
One half life is 1.3, so another half life brings it to 2.6. 2 half lives.
