List 3 characteristics of living things
- The ability to maintain homeostasis
- The ability to reproduce
- The ability to respond to the environment
The application of a general principle to predict a specific result is an example of
deductive reasoning
Provide an example of horizontal gene evolution
Bacteria acquiring resistant genes from the environment
Why are viruses not considered living things
They cannot reproduce without a host cell
What information to scientific names provide ?
Genus and Species
A researcher predicts that chemical X will make plants grow taller and designs an experiment to test the prediction. In the experiment, the height of the plants is the ?
Dependent variable
A bird on a cold night shivers to maintain its body temperature. What property of life does this example represent?
homeostasis
True or Fals: All of the cells in your body have the exact same DNA. This means that they also all have the exact same proteome.
False
Using pollen grains to study climate change is an example of
Using indirect evidence
Why are pollen useful for studying climate change?
They are resistant to decay
They are unique to a plant species, such that each species produces its own pollen
A researcher has pollen grains in 6 layers from one location, just as you have completed. She finds that as she moves from layer 6 to layer 1, the plants are from warmer habitats. From this, she argues that there is global warming. What is the problem with this conclusion?
Her sample size is too small
