If you were to draw a punnet square of two individuals with the genotypes Ss, there would be 1 box with ss, 2 boxes with Ss, and 1 box with SS.

Pepsinogen, an inactive zymogen, is secreted into gastric juice from both mucous cells and chief cells. Once secreted, pepsinogen is activated by stomach acid into the active protease pepsin, which is largely responsible for the stomach's ability to initiate digestion of proteins.
Answer:
D) resource partitioning.
Explanation:
Resource partitioning explains how species that are similar (in this case the two-spot and the three-spot avenger beetles) use their resources together (coexist). They live in the same community and use the same resources, but they don't push one another to extinction through competition. They use the same limiting resource at different time and thus, compete less with one another.
