Answer: The digestive tract starts by chewing and swallowing food. From there the food travels down the esophagus easily because it goes with a liquid Siliva enzyme. After, the food goes into the stomach where it is processed into a thick liquid called chyme. It then travels to the lower part of the stomach known as the atrium where it is ready to be released into the small intestine. The small intestine, or small bowel, is a hollow tube about 20 feet long that runs from the stomach to the beginning of the large intestine. The small intestine breaks down food from the stomach and absorbs much of the nutrients from the food. The food then travels to the large intestine where salts and sugars that could not be digested are absorbed. The rectum stores the stool, then the anus pushes it out in a bowl movement.

Before you preform CPR, if the person is unconscious and is not responding to questions (such as: "Are you okay?) call 911 or the local emergency number, and get an AED, if one is available. As soon as the AED is ready, deliver one shock if instructed by the device, then begin CPR
Answer: Homeostasis refers to stability, balance, or equilibrium within a cell or the body. It is an organism’s ability to keep a constant internal environment. Homeostasis is an important characteristic of living things. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is called homeostatic regulation. Because the internal and external environments of a cell are constantly changing, adjustments must be made continuously to stay at or near the set point (the normal level or range). Homeostasis can be thought of as a dynamic equilibrium rather than a constant, unchanging state.
Feedback Regulation Loops
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted. Then, the response to a stimulus changes the internal conditions and may itself become a new stimulus. This self-adjusting mechanism is called feedback regulation.
Feedback regulation occurs when the response to a stimulus has an effect of some kind on the original stimulus. The type of response determines what the feedback is called. Negative feedback occurs when the response to a stimulus reduces the original stimulus. Positive feedback occurs when the response to a stimulus increases the original stimulus.

<h2>Answer:</h2>
Paramecium is the single celled organism (unicellular).
<h3>Explanation:</h3>
- An organism which contain only one cell is known as unicellular organism.
- Paramecium is the unicellular parasite. It can move and digest food.
- In its structure there are food vacuoles for the digestion of food.
- Paramecium is the eukaryotic organism because it has a well organised cell with distinct nuclear membrane.
