Answer:
The correct answer is "Jim’s heart rate decreased quickly after 30 minutes since he is in good shape".
Explanation:
I attached the missing graph and the missing options of this question are:
Jim’s heart rate was 60 beats per minute at the start of the test.
Jim’s maximum heart rate during the test was 140 beats per minute.
Jim’s heart rate increased steadily as he continued exercising.
Jim’s heart rate decreased quickly after 30 minutes since he is in good shape.
The correct answer is "Jim’s heart rate decreased quickly after 30 minutes since he is in good shape".
While the first two statements are correct, since they point out data from the graph, the only statement that makes an inference based on the information of the graph is the last one. An inference is a conclusion that was reached base on evidence. In this case, the inference is that Jim is in good shape, and the evidence that was used to reach this conclusion is that his heart rate decreased quickly after 30 minutes.

Small leaves protect desert plants from animals that eat plants.
In the block to polyspermy, entry of the sperm's contents causes calcium ion levels in the oocyte's cytoplasm to rise, triggering the cortical reaction.
In biology, polyspermy describes the fertilization of an egg by more than one sperm. Diploid organisms normally contain two copies of each chromosome, one from each parent.
The cell resulting from polyspermy, on the other hand, contains three or more copies of each chromosome—one from the egg and one each from multiple sperm. Usually, the result is an unviable zygote. This may occur because sperm are too efficient at reaching and fertilizing eggs due to the selective pressures of sperm competition.
The cortical reaction is a calcium-dependent exocytotic process in which the content of secretory granules is released into the perivitellin space immediately after fertilization, which serves to prevent polyspermic fertilization.
