The table shows data Chargaff collected on DNA nitrogenous bases in five organisms. What can you conclude from the data in this table? How does the double-helix model of DNA explain Chargaff’s rules of base pairing?

1. is geographic distribution

2 is increasing complexity

3 is transitional forms

the answer is d. embryo

mathematical model hope this

i think i can answer even without the example. over time with environmental changes, sometimes a group of animals will adapt to better survive. take a moth for example. if the trees the moths use to camouflage themselves from predators, started to die or change colors themselves, the moths may, overtime of course, change color too. its just adapting to its surroundings. hope i was of any : )
