b. convert the chemical energy in sugars into ATP
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:
Antibiotics are chemicals that kills the growth of bacteria and can be used in the treatment of bacterial infections. They work by breaking the cell wall of bacteria.
In turn antibiotics are produced in nature by soil bacteria and fungi.
Answer:
A & C
Explanation:
During creation of the solar system, the materials with higher melting and boiling point within the nebulae were able to coalesce close to the sun because they are less volatile. These materials also happen to be denser. Denser materials have more mass and therefore pulled on more by the gravitational forces of the sun. The more volatile material such as gases was able to coalesce further from the sun –where the gases can cool below boiling and melting points- to form the gas giants such as Jupiter.
