The muscles in the stomach aid in digestion by
a. secreting bile
b. churning, or mixing, food
c. opening and closing the stomach
d. absorbing nutrients

The correct answer would be b. churning, or mixing, food.

Stomach helps in mechanical and chemical digestion of the food.

In mechanical digestion, the smooth muscles of the stomach physically break down the food into the smaller pieces so that acids and enzymes can digest the food more efficiently.

The muscles of the stomach undergo peristaltic contractions to squeeze the food which results in the churning of food as well as its mixing with acids and enzymes.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.

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.
