Digestion refers to the breakdown of large food molecules into small food molecules so that can be absorbed by the blood. There are two types of digestion i. e. mechanical digestion and chemical digestion. in mechanical digestion, the food is broken down into smaller parts physically with the help of teeth while on the other hand, in chemical digestion, food is broken down into small particles with the help of chemicals such as acids and enzymes. This chemical digestion is carried out in the stomach where different types of chemicals are present.

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.

Explanation:
Chromosomes are present in cell nucleus and consist of chromatin. Genes are present in linear order on chromosomes. The chromosomes become visible under the microscope as distinct structures during cell division. When cells are not dividing, the chromosomes decondense to loose their individuality and make the mass of chromatin.
Chromatin is complex of DNA and packing proteins. As the cells enter the prophase stage of cell division, condensation of chromatin occurs and individual chromosomes become visible under microscope. Before that (during interphase), chromosomes are not visible as they are present in decondensed form.
