How can scientific knowledge impact a decision about treating a disease outbreak?

During any outbreak or whenever problems occur, there are always three major steps to take.

1. First, is the containment action. In this step, actions are taken to reduce or lessen the severity of the people affected. This aims in isolating the disease. In this step, scientific knowledge is used in making decision on what containment actions to take.

2. Second is the corrective action. This step focuses solely on formulating medicine to treat the disease. Once again scientific knowledge is used in creating those medicines.

3. Third is the preventive action. To prevent this disease outbreak from recurring, certain actions are made to ensure this does not happen again.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
