These bacteria can exist for long periods of time in air, dust, water, and food, as well as on environmental surfaces. Rhinovirus is a type of virus that can cause the common cold in humans. Rhinovirus cannot survive outside of a human host for more than a few hours.

C. Bacteria can cause infections in the human body, whereas there are no types of viruses that can cause infections.

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.

The organelle pictured is found in cells of and is theorized to have once been an independent organism.
