After sitting for many hours during a trans‑pacific flight, a passenger jumps up quickly as soon as the "fasten seat belt" light is turned off, and immediately falls to the floor, unconscious! within seconds of being in the horizontal position, however, consciousness is restored. select the option that completes the explanation of what happened.
upon standing, there is a time lag before the person’s heart responds to the:
o increased downward force of the top of her head on her blood. lying horizontally removes the downward force.
o increased pressure difference between her feet and her head. lying horizontally reduces the pressure difference.
o reduced fluid density in her brain, which causes a lack of oxygen. lying horizontally restores the proper fluid density.
o rush of blood and other fluids up into her head. lying horizontally equalizes her fluid levels once again.

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.
