- How does the scaling of surface area to volume ratio limit the size of cells? body cells cannot be too small because they would not be able to get oxygen across their membranes fast enough to accommodate all of their mitochondria "body cells cannot be to small because they would not have enough surface area to get rid of CO2, urea, and other nitrogenous wastes fast enough body cells cannot be too large because organelles and enzymes deep in the interior would not be able to get enough O2 or nutrientsIntroduction to Science EXERCISE 1: DATA INTERPRETATION Dissolved oxygen is oxygen that is trapped in a fluid. Since many living organisms require oxygen to survive, it is a necessary component of water systems (streams, lakes, rivers, etc.). Dissolved oxygen is measured in units of parts per million (ppm). Examine the data in Table 4, which shows the amount of dissolved oxygen present in a body of water and the number of fish observed in the sample. Then, answer the questions below. Table 4: Water Quality vs. Fish Population Dissolved Oxygen (ppm) 0 2 4 6 8 10 12 14 16 18 Number of Fish Observed 0 1 3 102 13 15 10 12 13 1.

O Salmon use complex, carbon-based molecules obtained directly from seawaterr and the atmosphere to produce other complex molecules, such as fats. O Salmon use the carbon, hydrogen, and oxygen atoms obtained directly from seawater and the atmosphere to form sugars and proteins. O Salmon break bonds in complex food molecules to release the carbon, oxygen, and hydrogen atoms needed for the formation of other molecules. O Salmon break down carbon, hydrogen, and oxygen atoms obtained from food into smaller, energy-rich elements.
- Another student places some of the bread from their sandwich near these objects and leaves them overnight. The next day, they notice that some of the bread is gone and decide that these are living things and they ate the bread. Which is the best evaluation of their argument? (a) They are wrong, some living things eat food, but others get energy in other ways. (b) they are mostly wrong. Plants don’t need energy or food, they survive off of heat from light. These could be plants (c) They are somewhat correct. Some living things eat food, but others don’t need energy to survive (d) They are correct. All living things need energy and they must have eaten their bread.Describe why hydrogen, carbon, nitrogen, and oxygen can be considered the most important building blocks for living organisms. Please focus your response on the material you have learned in this course which is Essentials of Organic and Biochemistry.What distinguishes living things from non-living things?
