What does Osteocytes secrete?
Osteocytes become surrounded by bone matrix and are relatively inactive, but do have the capability to produce components needed to maintain the bone matrix if needed. Lacunae osteoblasts change into osteocytes.
Why is reproduction needed?
Without reproduction, evolution could not occur. Thus, organisms would be unable to adapt to the environment over evolutionary time. Moreover, without reproduction an organism would not be able to produce copies of itself. That means that when that organism dies, there would be no more of that organism. Life would quickly extinguish in this way.
How will the allele change in the rat population?
Evolution is the change in allele frequency over time in a population of organisms. Rats too!
What are the stages for selective breeding?
Overproduction :organisms produce more offspring than the environment can support. I herited Variation :organisms are very different have variation in there genes that causes them to have different them to have different traits that are passed don to their offsprings.Adaptation Different traits can offer advantage in different environments. Natural Selection :over time the useful trait will become more common in the population always remember VANS

Why is variation important for natural selection and what are the main sources of this variation?
Without variation natural selection would have nothing to select from that would confer survivability and reproductive success. on the organisms being selected against the organisms conspecifics and the immediate environment. Mutation and sexual recombination provide the main sources of this variation that is needed to make selection work. Mutation is the variation presented that causes the real adaptive change that can lead to speciation.
