Assuming negligible inbreeding and recombination loss, calculate the proportion of F1 hybrid vigor retained in advanced generations of each of the following composite beef breeds: RX3 (1/2 Red Angus, 3/8 Hereford, 1/8 Red Holstein)
Barzona (approximately 1/8 Hereford, 5/32 Angus, 3/8 Afrikaner, 5/16 Shorthorn, 1/32 Brahman) (1 pt)
What generalized statement can be made about the difference in retained vigor for these two composite groups?

not sure if this is what you'r looking for eubacteria and archaebacteria

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.

a plastic spoon that has a temperature of 78° f is placed into a bowl of soup that has a temperature of 84° f. which of these correctly describes what will happen?

energy as heat moves from the soup to the spoon.
