Scientists collected samples of each group of flies. They placed some of the flies, together, in flasks with both apples and hawthorn fruit. Other flasks contained either apple-eating flies or hawthorne-eating flies. Only the flies in the single fruit flasks mated and
produced offspring. To confirm their results, the scientists isolated flies from each group and put one of each into a flask with food.
Eventually the flies died
without mating. What conclusions apply to this situation? All BUT ONE could apply.
A)One fly species became two species via natural selection.
B)By eating different fruits, the flies changed genetically.
C)Over time, each group evolved different traits that aided in their survival.
D)Living in the ground and emerging a different times was a kind of
geographic isolation

1. the passing of is the basis of heredity. 2. our encode the instructions that define our traits. 3. each of us has thousands of genes, which are made of and reside in our chromosomes. 4. in addition to our genes, the we live in also define our traits. 5. humans have two complete sets of chromosomes. 6. when parents conceive a child, each parent contributes set of chromosomes. 7. every child receives of its chromosomes from the mother and half from the father. 8. this transfer takes place at when the father’s sperm joins the mother’s egg. 9. while most cells in our bodies have two sets of chromosomes, or a total of egg and sperm each have chromosomes. 10. when egg and sperm unite they create a single cell called a 11. each parent contributes complete set of chromosomes to their child. 12. since the parents contribute the chromosomes to each new child, every child inherits a unique set of chromosomes. 13. as a result, every baby will have a combination of traits.
