Chapter 33.2, Problem 2TYK

The resting membrane potential occurs because

  1. the membrane is leaky to Na + and K + .
  2. the concentrations of Na + and K + are unequal across the membrane.
  3. the Na + / K + ATPase pump moves two K + into the cell for every three Na + it moves out of the cell.
  4. a and b are correct.
  5. a, b, and c are all correct.

Describe and give a specific example of how successionary stage is related to species diversity?
Explain down bellow what happens to the cell in pictures not in words: Decreased pH in mitochondria Increased ATP Decreased pH in cytosol Increased hydrolysis Decreasing glycogen and triglycerides Increased MAP kinase activity Poor ion transport → For each one:→ What normally happens?→ What is wrong now?→ How does it mess up the cell?
1.) Community Diversity: The brown and orange line represent two different plant communities. a. Which color represents the community with a higher species richness? b. Which color represents the community with a higher species evenness? Relative abundance 0.1 0.04 0.001 2 4 6 8 10 12 14 16 18 20 22 24 Rank abundance c. What is the maximum value of the Simpson's diversity index (remember, Simpson's index is D = p², Simpson's diversity index is 1-D)? d. If the Simpson's diversity index equals 1, what does that mean about the number of species and their relative abundance within community being assessed?
