From what I know the <u>cranium</u> protects the organ called the <u>brain</u>. It is made up of 8 different bones that supports your head & protects your brain from injury. Some of the other bones protect the sides of the <u>brain</u> & supports the sides of your face. The <u>cranium</u> is basically a cozy little home for your <u>brain</u>.
Answer:
The fins will be a different color since their proteins for fin color are different so the proteins will connect in different ways.
Explanation:
I took the test and got 100%
A=P(1/2)^(t/h)
A=final amount
P=initial amount
t=time
h=half life
so
h=1.3 billlion (just write 1.3 and remember to mulipy the end time by 1 billion)
and final amount is 25% of original or 0.25P
0.25P=P(1/2)^(t/1.3)
divide both sides by P
0.25=(1/2)^(t/1.3)
take ln of bot sides
ln(0.25)=ln((1/2)^(t/1.3))
property of logarithms
ln(0.25)=(t/1.3)ln(1/2)
divide both sides by ln(1/2)
(ln(0.25))/(ln(1/2))=t/1.3
times both sides by 1.3
(1.3ln(0.25))/(ln(1/2))=t
remember that this is billion so
(1,300,000,000ln(0.25))/(ln(1/2))=t
2600000000.0001=t
about 2.6 billion years
