Answer:
5732 years
Explanation:
Radioactive decay can be determined by using the equation:
where;
= number of decayed atoms at time (t)
= initial number of decayed atoms
= decay constant
So, if we equate the natural log of the above; we have:
where;
= 
= 
= 
t = 5732.01 years
t = 5732 years.
Hence, the fossil is 5732 years old.
An organism can get new cells from either cell growth where the numbers of organelles increase or during mitosis.
Answer:
The correct answer is - mitochondria lack ribosomes like prokaryotes.
Explanation:
The Endosymbiotic Theory says that mitochondria and chloroplast in eukaryotic cells are developed by the once aerobic bacteria that were engulfed by a large anaerobic bacteria.
This theory suggests the origin of eukaryotic cells. Various evidence exists such as mitochondria and chloroplasts contain their own circular DNA like prokaryotic cells and mitochondria and chloroplasts have 70S ribosomes like prokaryotes have.
Binary fission is a form of asexual reproduction,which is mitosis, and is used by unicellular organisms. (And learn how to spell if you want to do science)
