1. The modern synthesis combined the concepts of and evolution.
2. If a population is at Hardy-Weinberg equilibrium, the allele frequencies must be .
3. Seen more clearly in small populations, is when allele frequencies change due to random chance, not selection.

Respond to the following based on your reading.
4. What two fields does modern synthesis combine?
5. How does a genotype differ from a phenotype?
6. What's the most common type of mutation, and what impact does it have on natural selection?
7. What's the most common type of mutation observed in living populations, and what impact does it have on natural selection?
8. How does the reproduction of organisms impact the diversity of genes?
9. If a proportion of individuals in a species dies because of extreme heat, is this an example of genetic drift? Why or why not?

the cell is the smallest structural and functional unit of living organisms, which can exist on its own. therefore, it is sometimes called the building block of life. some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.

1. the geologists have established a set of principals that can can be used o determine the relative ages of rock. this principal is applied to sedimentary and volcanic rocks. the rocks exposed to wall of grand canyon has layers and by studying the number of horizontal layers in the rock(strata) the relative age can be determined. the layer first formed will appear at the bottom and the the layer of strata last formed appear at the top. by using this information the approximate age of rocks can be determined.

2. carbon dating is used to find the relative age of rock in numbers which means for the rocks that has age between 1-70,000 years.

3. for the rocks of age range between 1,000 - billion of years potassium-argon dating is used.
