Answer:
Explanation:
The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two major parts: The digestive tract (alimentary canal) is a continuous tube with two openings: the mouth and the anus.
Answer:
sour, corrosive
Explanation:
An acid is a substance that donates hydrogen ions. Because of this, in an acidic solution there are more hydrogen ions than hydroxide ions. This means the more acidic a food is, the more hydrogen ions are available to trigger the sour taste receptors. A base is a substance that accepts hydrogen ions.
Symbiosis can vary between mutualism, parasitism, and commensalism, tho these grade into each other, it is often difficult to tell which is involved in a given relationship.

Answer: The infrared radiations can detect the coolest and dimmest space objects.
In general, the coolest and darkest regions of space emit radiations of longer wavelengths. The Infrared telescope is used to find the cool, dim stars by slicing the interstellar dust bands and also measure the temperature of the planet of the solar system. The coldest stars do not emit light so they can be seen with the infrared telescopes only. In the visible region, blue stars are hottest and red are the coolest. The wavelength is inversely proportional to the energy emitted so the hottest stars are in the region of low wavelength in visible region.
