Final answer:
Howell's kiwis do not form a proportional relationship with the days passing, as they do not start at the origin. The amount of DNA in a kiwifruit and strawberry of similar size is not necessarily the same. At the market, Josh bought 1800 grams of fruit in total after conversions.
Step-by-step explanation:
The number of kiwis Howell has left is not proportional to the number of days that pass because the relationship between the two does not pass through the origin (0,0), i.e., when no days have passed, Howell still has 75 kiwis, not 0. Proportionality requires a constant rate of change that creates a straight line through the origin on a graph. Since Howell starts with 75 kiwis and loses 2 each day, this forms a linear relationship, but not a proportional one
Regarding the question about the amount of DNA in a kiwifruit and strawberry that are approximately the same size, this is a more complicated question that depends on the specific genetics of each fruit. The amount of DNA can vary widely among different types of organisms and isn't necessarily related to the physical size of the organism or its parts. Therefore, a kiwifruit and strawberry of approximately the same size would not necessarily have the same amount of DNA.
At the Farmer's Market
To determine how many grams of fruit Josh bought at the farmer's market, we need to first convert all quantities to the same unit. Josh bought 1.5 kilograms of oranges, which is 1500 grams, 150 grams of grapes, and 15,000 centigrams of apples, which is 150 grams. Adding these together, Josh bought 1800 grams of fruit in all.
