Which of the following is not a function of the strong hydrochloric acid present in the gastric juice?
a. the activation of pepsin
b. denature proteins
c. kill bacteria in food
d. breakdown starch
e. aid protein digestion

d. breakdown starch

Explanation:

The hydrochloric acid is produced by the parietal cells of the gastric glands present in the stomach. The primary function of the hydrochloric acid is to sterilize the food consumed by the human being. The acidic pH is unsuitable for the survival of the microbes present in the stomach. It triggers the activation of enzyme pepsin which is responsible for denaturation of proteins. The pepsin converts the protein into simple form of amino acids hence, facilitates the digestion of protein content in food.

The starch present in the food is digested by the enzyme called as salivary amylase present in the saliva present inside the mouth. The breakdown and digestion of starch is not the function of the hydrochloric acid.

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.  

the correct answer is 2 and 4
