There were 2 two species of rare caiman found in a river in Colombia. Scientists want to know if species A is significantly larger than species B based on the sampling of mass from these two populations. Help them out and conduct the proper t-test to tell them if their hypothesis is correct or not.

Which of the following statement is an incorrect observation from the Moody’s diagram? For a given relative roughness, the friction factor increases with increasing Reynolds number until the zone of complete turbulence is reached. As the relative roughness increases, the value of the Reynolds number at which the zone of complete turbulence begins also increases. Within the zone of complete turbulence, the Reynolds number has no effect on the friction factor. For a given Reynolds number of flow, as the...

Scientists were successful in creating Dolly the sheep using the nucleus isolated from a differentiated cell from an adult mammary gland. They transferred this nucleus to an enucleated egg and activated the egg to start development. Thus, the adult mammary gland nucleus could replace the nucleus created in the 1 cell zygote from the fusion of the egg and sperm genetic material. Wow! It's amazing that this works! 1) Describe in your own words how the success of reproductive cloning...
