The data in the graph are the result of a paramecium being placed in a hypertonic salt solution. A graph entitled Paramecium Contractile Vacuole Contractions has salt concentration on the horizontal axis and contractions per minute on the vertical axis. A very low salt concentration has 30 contractions per minute, low: 22, medium: 15, high: 8, very-high: 2. What change would most improve the usefulness of the graph? Replace the concentration descriptions with actual values. Plot contractions per second instead of contractions per minute. Remove the plotted points and just keep the line. Remove the name of the organism from the title.

Compare the parts of a cell and the cell as a whole to another common nonliving system (i.e., a car, a city, describe the parts of a cell and their primary function.

The table below shows the elements that mainly comprise each of the four layers of earth: elements in layers layer main elements crust oxygen, silicon mantle iron, magnesium outer core iron, nickel inner core iron which of these elements make up the layer that is 0.2 to 1.1 percent of earth's total diameter?

All fats are part of a larger group known as lipids. lipids come in a variety of forms in food, including triglycerides, phospholipids, and sterols. choose the statement below that correctly describes the types of lipids found in foods. all fats are part of a larger group known as lipids. lipids come in a variety of forms in food, including triglycerides, phospholipids, and sterols. choose the statement below that correctly describes the types of lipids found in foods. triglycerides contain two fatty acids attached to a glycerol backbone. the body does not manufacture phospholipids, so they must be included in the diet. about 95% of the fat you eat is in the form of sterols. sterols like cholesterol have a ring structure.
