Imagine a mutation that causes a neuron to synthesize and incorporate an abnormally large number of potassium leak channels into its plasma membrane. Assume the neuron is otherwise "typical" (all other channels and pumps are unaffected in terms of function or number, ionic concentration gradients across the cell membrane are "typical" for a mammalian neuron, etc.). What will be true of this neuron?

How do ecosystem respond to nature disasters such as fires and floods

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.
