Summary Introduction

To review:

1. The anatomical reason that allows the fluids to come out from the nose.

2. The structure preventing the downward flow of milk into the nose during drinking in an upside down position.

Introduction:

The passage of food into the alimentary canal and the conduction of air to the lungs are done by two separate structures. These are composed of various different components. The respiratory and the digestive passage have a common point of interception in the region of mouth but the interface is separated by a valve.

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?
