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.

What does a dominant trait and recessive trait mean (if you cheat you dont get the brainliest)

Use the drop-down menus to decide if an example of similar traits is likely a homologous structure or an analogous structure.

snow_tiger [21]

Answer:

- Bird wings and dragonfly wings are both used for flight: Analogous structure

- Clams and snails both have similar muscle structure even though the muscles do different jobs: Homologous structure

- Human and giraffe necks both have 7 vertebrae because we are related: Homologous structure

- The flaps of a Venus flytrap have a similar makeup to oak leaves: Homologous structure

Explanation:

Analogous structures are similar structures that have the same or similar functions in unrelated organisms. Analogous structures aren't the result of evolutionary relationships among organisms (i.e., they were not inherited from a common ancestor). On the other hand, homologous structures are structures inherited from a common ancestor. Homologous structures may or may not have an identical function, but they are the result of evolutionary relationships among organisms and, therefore, they are genetically related.

A solution containing HCI would likely have

harkovskaia [24]

Answer:

A solution with HCl would likely have a low pH and a high pOH. Hydrochloric acid or HCl, from the name itself is acidic its pH is always below neutral pH or 7. pH is the measure of the concentration of hydronium ions (H3O+) in a solution while pOH is the measure of the concentration of hydoxide ions (OH-) in a solution. A relationship exist between the two values of a solution where pH + pOH = 14 therefore when the pH is low, consequently, the pOH is high.
