They then predict the eruption of that volcano.3. When a volcano erupts, the amount of carbon dioxide and sulfur dioxide emitted decreases. 4.Scientists measure the amount of these gases to determine the amount of magma present in the volcanic reservoir.

Question from Campbell Biology Chapter 23: 72) Swine are vulnerable to infection by bird flu virus and human flu virus, which can both be present in an individual pig at the same time. When this occurs, it is possible for genes from bird flu virus and human flu virus to be combined. If the human flu virus contributes a gene for Tamiflu resistance (Tamiflu is an antiviral drug) to the new virus, and if the new virus is introduced to an environment lacking Tamiflu, then what is most likely to occur? A) The new virus will maintain its Tamiflu-resistance gene, just in case of future exposure to Tamiflu. B) The Tamiflu-resistance gene will undergo mutations that convert it into a gene that has a useful function in this environment. C) If the Tamiflu-resistance gene involves a cost, it will experience directional selection leading to reduction in its frequency. D) If the Tamiflu-resistance gene confers no benefit in the current environment, and has no cost, the virus will become dormant until Tamiflu is present.

Frogs have lungs for breathing, but they also absorb dissolved oxygen directly through their skin. This allows respiration to occur when they are underwater. When they are on land, mucus keeps their skin moist to continue to absorb dissolved oxygen from the air. Which statement about water is best illustrated by this example? Liquid water can transport nutrients. Water breaks down into oxygen molecules for respiration. Water is found in every cell of an animal’s body. Liquid water is necessary for plants and animals.
