b. churning, or mixing, food
c. opening and closing the stomach
d. absorbing nutrients
The muscles in the stomach aid in digestion by churning, or mixing, food. Hence, option C is the correct answer.
Digestion is the complex process of turning the food you eat into nutrients, which the body uses for energy, growth and cell repair needed to survive.
The stomach is a muscular sac that lies between theesophagus and the small intestine in the upper abdomen.
The stomach is not the only part of your digestive system that absorbs food but rather is a part of the digestive system and important for churning food into a consistency that is easier to digest for the rest of your intestines.
Hence, option C is the correct answer.

Question
Answer:
The answer is D
b. the atmosphere and hydrosphere
c. the geosphere and hydrosphere
d. the geosphere, hydrosphere, and atmosphere
D) The geosphere, hydrosphere, and atmosphere
During the carbon cycle, various processes move carbon from the geosphere to the atmosphere such as volcanic eruptions release carbon dioxide from molten rock beneath the earth's surface to the atmosphere. Carbon can leave the soil through soil respiration which releases CO2, or by erosion which can carry it into rivers or the ocean, where it then enters the hydrosphere. Carbon is found in the hydrosphere dissolved in ocean water and lakes and hence the cycle continues.
The carbon cycle is the biogeochemical cycle which involves an exchange of carbon among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
Carbon is the most important component of the biological compounds such as limestone. Also, during soil respiration, Carbon can leave the soil through it which releases , which carries it into the rivers or the ocean, where it then enters the hydrosphere.
Thus, option D is correct.
