Answer: The correct answer is D. Ingestion, digestion, absorption, elimination.

Explanation-

Digestive system is an example of organ system, which acts upon the food (taken in by the organism) with the help of physical and chemical means so as to provide absorbable nutrients to meet the demands of the body.

In mammals, the digestive system includes the alimentary canal, which begins from mouth and ends with anus.

Food is first ingested by the mouth, then it is digested by different organs like mouth, stomach, and finally small intestine. The digested food is absorbed in the small intestine and the undigested food is eliminated from the body via anus in the form of fecal matter.

Thus, option D) is the best sequence of the function that digestive system performs.

Ceruminous glands are ________. Ceruminous glands are ________. saliva glands found at the base of the tongue modified taste bud
kogti [31]

Answer:

Modified apocrine sweat glands

Explanation:

The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.

As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.

This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.

Ceratium fusus is a protist that is found primarily in coastal waters, especially around the coast of the United Kingdom. These
kotykmax [81]

A chemical defense mechanism is called bioluminescence.

As mentioned in the reaction, Ceratium fusus undergoes a special chemical reaction at night which helps them defend themselves from predators. During this reaction, light is produced inside a living organism. However, this type of reaction does not produce heat although it does produce light.

<h3>What is bioluminescence used for?</h3>

The most well-known purpose of bioluminescence is to defend the organism against attacks by predators. This is because the light confuses or frightens predators.

Besides confusing the predator, the light can also alert large predators to approach the location of the organism, in this way this large predator will eat the predator that is threatening the organism which in our question, is Ceratium fusus.

Many marine organisms use the phenomenon of bioluminescence for their defense, in particular marine invertebrates, vertebrates, certain micro-organisms as well as certain fish and fungi.

Hence concluded that the bioluminescence characteristic of Ceratium fusus is being described.
