Which example is an organism?

ss7ja [257]

The answer is A.
Why: The heart is part of an organism, so that doesn't exactly count. Soil is not alive, and neither is clay. Therefore, Bacteria must be it. Bacteria is a living thing, and can function by itself.

Jim's heart rate was monitored during periods of exercise and periods of rest. The graph shows the result of one 50-minute

DaniilM [7]

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.
