Question

7)What evidence was found from soft tissue samples of a remarkably well-preserved Tyrannosaurus rex that provided molecular evidence linking T. rex to a chicken? (1 point)
a. Antibodies that react in a specific way with chicken proteins reacted in the same way with T. rex proteins.***
b. Oxygen was found to be essential to T. rex’s survival in the same way that it is essential to a chicken’s survival.
c. T. rex cell structure was found to be similar to the cell structure of chickens.
d. T. rex cells were found to use glucose as a source of energy just like a chicken’s cells use glucose.

Answer 1

The right answer is A, antibodies that react in a specific way with chicken proteins reacted in the same way with T. rex proteins. Here i want to share some interesting information about chicken IgY antibody. Here is the link: https://www.creativebiolabs.net/chicken-igy-antibody_59.htm

Answer 2

A T-Rex  and a chicken were found to have similar cell structure but was also found to both use glucose as a souse of energy.........glucose+oxygen=carbon dioxide+water+nutrients.
