Answer:
Wall of stomach : it has three layers of muscle instead of two. Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta. The epithelium of the stomach forms deep pits, called fundic or oxyntic glands.
wall of ileum : The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. The ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion.
Answer: Bees are attracted to different plants as these plants have adapted to show vibrant colors, open/flat tubular flowers, and have scents that appeal bees.
Explanation: How bees are attracted to flowers and plants is a very different world which we cannot see with our naked eye. Plants usually use their own chemicals and figures to attract bees, and bees rely on flowers for nectar and pollen. This relationship between bees and plants is very necessary for the growth of most of our food, which includes: grapes, cabbage, cherries, chestnuts, raspberries, sunflowers, strawberries, cucumber, and more. It has been an evolutionary adaption for plants to attract bees in natural ways.
