The graph illustrates the activity level of three common digestive enzymes, across a range of ph values. calculate the ph range in which pepsin will be effective to some degee?

The graph shows that the activity of pepsin is zero at a pH level between 9-12. This means pepsin does not work properly in basic conditions.  The enzymes start to function slightly between pH 8 to 8.9. Below this pH, the activity of the enzyme, pepsin, gets better and better and it is most effective when the pH of the solution is round about 2. This graph illustrates that pepsin works best in acidic conditions.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
