Different radioisotopes have different half-lives. For example, the half-life of carbon-14 is 5,700 years, the half-life of uranium- 235 is 704 million years, the half-life of potassium- 40 is 1.3 billion years, and the half-life of rubidium-87 is 49 billion years. a. Why wouldn't you use an isotope with a half-life similar to that of carbon-14 to determine the age of the Solar System? b. The age of the universe is approximately 14 billion years. Does that mean that no rubidium- 87 has decayed yet?

a. You wouldn't use an isotope with a half-life similar to that of carbon-14 to determine the age of the Solar System because the timescale involved in the formation of...

Two students have compared the genome wide analyses of expression profiles in the leaves of maize and they found that the leaves of maize either do or do not develop Kranz anatomy. Please explain.

Expression profiles are used to compare the levels of gene expression. Kranz anatomy is a structure observed in C4 plants where the mesophyll cells cluster around the bundle-sheath cell in...

I would like to know if different lobes of the liver produce different levels of catalase. If so why? Any research or pointers are extremely helpful! Thankyou.

Different lobes of the liver produce different volumes of catalase because of their size (for example, the right lobe needs to produce more than quadrate lobe). While hepatocytes are the...
