I hope they are. Hopefully they are taking hundreds of samples from hundreds of different animals so they can someday reintroduce them without having to worry about "imbreeding" that would occur if they only had samples to clone a few copies.
I would think scientists would be accumulating an entire library of as many samples of DNA as possible for use with cloning technology is perfected more.

Spring scale A is attached to the floor and a rope runs vertically upward, loops over the pullley, and runs down on the other side to a 120-N weight. Scale B hangs a 120-N weight. What are the readings of the two scales A and B? The weights of the scales are negligible.

Any help is appreciated...Thanks

For all you birders out there. The literature seems mixed. Some say they are two species - the Bullocks Oriole and the Baltimore Oriole. Some say it is just one - the renamed 'Northern Oriole'.
Opionios? Thanks in advance.

The coefficient of static friction between a block and a horizontal floor is 0.40, while the coefficient of kinetic friction is 0.15. The mass of the block is 5.0 kg. A horizontal force is applied to the block and slowly increased. (a) What is the value of the applied horizontal force at the instant that the block starts to slide? (b) What is the net force on the block after it starts to slide?
