Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.
B, probably because they animals would probably die, making it harder to find if every albino animal kept dying.
Blood is isotonic to cells in order to conserve the shape and structure of the surrounding cells.
- Isotonic solutions are solutions that have the same concentration of water on both sides of a cell membrane.
- In this case, the blood is an aqueous fluid that exhibits isotonic properties compared to its surrounding cells.
- Isotonicity enables the blood to transport oxygen and nutrients to the cells but simultaneously conserves the structure and form of these cells.
In conclusion, blood is isotonic to cells in order to conserve the shape and structure of the surrounding cells.
