1. a massive body can bend the path of a beam of light as it travels through space, it causes light
to travel on a
path rather than along a straight line.
2. light waves compress as an object is moving toward an observer, causing the light to shift to
the
end of the electromagnetic spectrum
3. black holes can't be observed directly because they don't produce
so the location is
identified by examining the motion of nearby stars.
4. even less understood than dark energy is dark
making up 27 percent of matter in the
universe and cannot be observed with light.
5. holding the milky way together is accomplished by the provided by a supermassive
black hole near the center of the galactic bulge.
respond to the following based on your reading,
6. explain why the galactic disk appears blue and the galactic bulge appears red

Simulating adaptations in a species in this activity, you will discuss in detail the adaptations in a species of rain forest plants. you will build a simulation that explains the changes in the traits of the plant population over 10 years. you will also establish a scientific explanation to justify the changes in the traits of the population, * time to complete: 1-2 hours part a an organism's adaptations are specific to its native environment. an organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. the following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in canada, and a tropical rain forest in belize. evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. in your answer, explain the survival challenges that plants face in these two environments.
