The best precaution against carbon monoxide poisoning is to keep air moving through the boat.
Carbon monoxide is a potentially deadly gas that is produced any time a carbon-based fuel burns. If you suspect carbon monoxide poisoning you must do the following: open doors and windows, turn off gas appliances. To determine if a person is poisoned by carbon monoxide you may look for the following signs and symptoms: dull headache, weakness, dizziness, nausea or vomiting, shortness of breath, confusion, blurred vision, loss of consciousness.
1. The correct answer is pH.
The activity of the enzymes might be affected by environmental changes such as change in pH. Each enzyme has the point when it is the most active and this value is known as the optimum pH. Extremely high or low pH values can lead to loss of enzyme activity and stability.
Phosphofructokinase is sensitive to acidity, meaning that it is inhibited by low pH levels.
2. The correct answer is temperature.
Enzyme is sensitive to the environmental conditions such as temperature changes.
Temperature is a factor that usually increases the rate of enzyme-catalyzed reactions by increasing the activity of enzymes. But, after reaching the optimum temperature, reaction rate abruptly declines. This happens because enzymes are deactivated or denatured at a certain temperature (above 40° C).
The brain injury suffered by Phineas allowed psychologists to learn about the functions of the brain's FRONTAL LOBE.
The man case was the first one in which a brain damage will result into a change in personality. The damage to the Phineas frontal lobe helped scientists to recognize the connection between the frontal lobe of the brain and social cognition and decision making.<span />

Answer:
D. Water
Explanation:
the covalent bonds of water are stronger than the ionic bonds in the salt molecules so they dissolve.
