40) Describe the structure of a mammalian respiratory system. Include in your discussion the mechanisms of inspiration and expiration. In mammals‚ oxygen first passes through the nasal cavity. The nasal cavity is covered with mucus and cicilia to filter the air. The nasal cavity leads to the pharynx. The pharynx consists of the eustachian tube and the tonsils. The inhaled air then passes to the larynx‚ trachea‚ and bronchi. The bronchi lead to the bronchioles in the lungs. In the lungs the pleural

The large molecules of all living things fall into just four main classes. Name them. Explain what is meant when we say a molecule is amphipathic. 3. In the 1960s‚ the Davson-Danielli model of membrane structure was widely accepted. Describe this model and then cite two lines of evidence that were inconsistent with it. 4

This file of BIO 100 Week 4 Discussion Questions shows the solutions to the following problems: DQ 1: Post your response to the following: What are some of the benefits of squeezing so much data into virtually every cell in the body? Why did humans not evolve with one central repository of DNA rather than having it replicated throughout the body? Assume that the hereditary information carried in genes and DNA is responsible for many differences observed in humans and other living things. How
