This is the final product of photosynthesis that animals consume
as an energy source

![Page 7: Second Semester](https://reader031.fdocuments.us/reader031/viewer/2022020220/56812c81550346895d9134df/html5/thumbnails/7.jpg)

Molecules of Life 400
When enzymes are placed in an environment with a different pH, this is
most likely to occur.
The enzyme would not work outside their optimum range
![Page 13: Second Semester](https://reader031.fdocuments.us/reader031/viewer/2022020220/56812c81550346895d9134df/html5/thumbnails/13.jpg)

Evolutionary Biologist 100
A structure that once had a function but now is useless.
Vestigial structure!
![Page 20: Second Semester](https://reader031.fdocuments.us/reader031/viewer/2022020220/56812c81550346895d9134df/html5/thumbnails/20.jpg)

different function.

List when and where mutations occur in order for it to become part of the population
When: before reproductionWhere: in the gamete (sperm or egg)
![Page 23: Second Semester](https://reader031.fdocuments.us/reader031/viewer/2022020220/56812c81550346895d9134df/html5/thumbnails/23.jpg)
Evolutionary Biologist 500
Give an example of evidence provided from an evolutionary biologist that helps provide
evidence for common ancestry, yet change over time?
Common ancestry- similar parts (homologous) in different organisms;
change- have different functions
![Page 24: Second Semester](https://reader031.fdocuments.us/reader031/viewer/2022020220/56812c81550346895d9134df/html5/thumbnails/24.jpg)
Evolution 100
This part of Darwin’s theory of Evolution shows this example: differences for Homo sapiens
(humans) can be exact size or shape of body, strength in running, or resistance to disease.
Variation
![Page 25: Second Semester](https://reader031.fdocuments.us/reader031/viewer/2022020220/56812c81550346895d9134df/html5/thumbnails/25.jpg)
Evolution 200
The part of Darwin’s theory of Evolution that explains that living space and food are limited so offspring from each generation must work against
themselves in order to live.
Competition
![Page 26: Second Semester](https://reader031.fdocuments.us/reader031/viewer/2022020220/56812c81550346895d9134df/html5/thumbnails/26.jpg)
Evolution 300
What is an adaptation? Provide an example.
An inherited trait that gives an organism an advantage to survive in its environment. Ex: Light
colored moth wings on light colored trees
![Page 27: Second Semester](https://reader031.fdocuments.us/reader031/viewer/2022020220/56812c81550346895d9134df/html5/thumbnails/27.jpg)
Evolution 400
This part of Darwin’s theory of Evolution explains that most species produce far more
offspring than are needed to maintain the population.
Overproduction
![Page 28: Second Semester](https://reader031.fdocuments.us/reader031/viewer/2022020220/56812c81550346895d9134df/html5/thumbnails/28.jpg)
Evolution 500
What is natural selection?
The process by which organisms with favorable traits have an increased chance to survive and
reproduce
![Page 29: Second Semester](https://reader031.fdocuments.us/reader031/viewer/2022020220/56812c81550346895d9134df/html5/thumbnails/29.jpg)
Natural selection is driven by this; it is what constantly changes, causing the
evolution of species.
Environment in which an organism lives.
