The muscular organ that digests food, called the stomach. It is a component of your digestive system (GI). When you eat, your stomach contracts and releases the acids and enzymes needed to break down the meal. Thus, option C is correct.
What is function of Stomach?In the anterior part of the abdominal cavity in most vertebrates, the stomach is a sac-like enlargement of the digestive system situated between the esophagus and the small intestine.
Before food is delivered into the intestine, it is mechanically distributed and stored in the stomach as a temporary container.
Carbohydrates are chemically digested in the stomach. Since the stomach only makes protease and lipase (pepsin breaks down proteins into peptides),
it is unable to chemically digest carbohydrate (gastric lipase that digests lipids into glycerides).
Therefore, Stomach is digestive organ in human

Chloe reads that given the correct conditions, cuttings from certain plants will form roots along the stem, enabling a new plant— identical to the parent plant—to grow. Chloe wants to investigate whether rooting hormone is beneficial or detrimental in this process. She takes cuttings from a shrub. For Group 1, she places some shrub cuttings in potting soil in partial shade. For Group 2, she dips some shrub cuttings in rooting hormone, places them in potting soil, covers them with a clear dome, and places them in direct sunlight. She waters the groups equally. She pulls up some cuttings after 3 days and again after 6 and 9 days to observe and measure root growth. Write a hypothesis for Chloe's experiment.
Answer:
The correct answer is - If you use the rooting hormone when cloning plants from cuttings, then it will be beneficial for the cuttings.
Explanation:
A hypothesis is a possible explanation or solution behind the particular natural world process or phenomenon. It is formed on the basis of the observation of the phenomenon or process, how it works or what characteristics it shows.
In this study, it is found that the root hormones promote the growth in the clonings from the cuttings of plants thus, the provided hypothesis is the correct hypothesis for the experiment given.
