The given question is incorrect. The correct question is as follows:
The muscularis externa propels materials from one portion of the digestive tract to the other by a series of wavelike contractions called peristalsis, while in most areas of the small intestine __________ movements churn and fragment digestive materials.
Answer:
Segmentation.
Explanation:
Digestion is the biological process that helps in the breakdown of the large food particles like carbohydrates, proteins into the small substances that are directly absorbed by the body for the production of energy.
The peristalsis movement occurs in the esophagus and other parts of the digestive system for the food propagation. The segmentation movement with the help of muscles also occurs especially in the small intestine for the proper mixing of the food and absorption by the body.
Thus, the correct answer is segmentation.
Answer:
This question appears incomplete
Explanation:
This question appears incomplete. However, generally speaking, <u>the higher the chloroplasts present in a plant, the higher the rate of photosynthesis that occurs in that plant</u>. This is because chloroplasts are cellular organelles that serve as sites in which photosynthesis occur. They are found in green plants and green algae.
Photosynthesis is the process in which green plants produce there own food by absorbing sunlight from the atmosphere in the presence of carbon dioxide and water. Hence, <u>it can also be said that an increase in the number of chloroplasts will lead to an increase in the amount of food produced by a plant (for itself)</u>.
From the description above, it can be said that the plant of a maple tree has a higher rate of photosynthesis and hence produced more food (for itself) than the leaf of a tomato plant.
Chloroplast also contain a green pigment called chlorophyll which is responsible for the green colour in green plants. Hence, an increase in the number of chloroplasts in a plant could indirectly imply greener plant. Hence, the plant of a maple tree could have greener leaf than the leaf of the tomato plant.
The amount of carbon dioxide will be higher on the city road because there are less plants to convert carbon dioxide to oxygen through the process of photosynthesis.
