QUESTION 16

Which of these is an example of evolution by natural selection?

1. Flowers growing under the shade of a tree are shorter than flowers of the same species growing in full sun.
2. Some bacteria are not killed by an antibiotic drug. These bacteria survive and reproduce. Over time the population of bacteria becomes more resistant to the antibiotic drug.
3. There is less grass growing in the center of a hiking path than along the edges of the path.
4. Scientists insert a gene into a tomato plant that makes it resistant to a disease called blossom end rot. These genetically modified plants do not have blossom end rot, but heritage tomatoes without the gene planted near them do get it.
