This would only affect how the molecule interacts externally with other hemoglobin molecules, as in choice A the correct answer. This question just asks you to read a graph and perform some basic calculations.

We can see from the graph that from day 3 to day 5, the population size grew from to individuals. This means that it increased by individuals in total. On this particular question, you could earn a maximum of 4 points one for each type of data you describe in part a and one for the explanation for each in part b.

Option 1 Data Description: This is consistent with the definition of a biological species Option 2 Data Description: Sufficient similarity between the DNA structures would support the existence of a single species Option 3 Data Description: Discovering the existence of fertile hybrid plant populations living between the two other populations of plants Explanation: This is also consistent with the definition of a biological species again, ability to produce fertile offspring There must be jobs out there for which you just have to collect plant samples.

Start building your experience now by never showering. On this question, you could earn up to 10 points in total. To earn these points, you have to: Create a graph that is correctly labeled, is correctly scaled, and uses proper units.

Part C is worth 5 points: You would earn 1 point for identifying a control treatment absence of herbivores. The final point would be earned by predicting experimental results that would support the hypothesis higher trichome density under the experimental conditions as compared to the control conditions.

This leaf is full of trichomes. There are no point deductions for incorrect or blank answers. Scoring is a bit more complicated on the free-response section which is scored by actual graders rather than a computer.

Three are scored out of 3 points, while the other three are scored out of 4 points. Finally, each long free-response question uses a point scale.
