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.

Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure cal
nevsk [136]

Answer:

The answer is 46 chromosomes.

Before mitosis, cell duplicates its DNA material so there are 46 chromosomes in duplicates and in total there are 46 x 2 = 92 sister chromatids. During mitosis, sister chromatids first join in the middle of the cell and then separate towards the opposite sides of the cell. After they separate, there are 46 sister chromatids on the one side and 46 sister chromatids on the other side. Each sister chromatid at the end of cytokinesis actually represents the chromosome of the newly formed daughter cell.
