One of the earlier estimate of the Hubble constant was 500 km/s/Mpc in early 1900s. In early 2000s, measurements of Hubble constant using Cephied stars yield 72 km/s/Mpc. In recent years, the new methods of using red giant stars has been developed and this new method yields 70 km/s/Mp. If you are to compare the 2 recent values, 72 or 70km.s/Mpc, which estimate will results in greater age of the universe?   t = 1/Ho Explain your reasoning in as much details as possible.

Question 1: Shyam Mohapatra The total number of immunoglobulin genes in humans are at 2.5 x 105, whereas the total repertoire of immunoglobulin diversity is estimated at 5 x 1013. How can there be so many Ig variants? 1a. “6 Pts” One of the key features of immunoglobulin and TCR genes is that there are multiple genes present in the genome. The accompanying Table lists a hypothetical number of variable, diversity and joining genes in humans for the heavy and c light chains. From this table, calculate heavy chain diversity, light chain diversity and total diversity.   1a. “ 7Pts” Is existence of multiple genes enough to explain all Ig diversity found in B cells. What mechanisms are in place create such diversity. What is the major mechanism of creating such diversity?
