When tissues are harmed by bacteria, trauma, heat, or any other cause, an inflammatory reaction occurs.

<h3>What happen when a honey bee stings?</h3>

When a honey bee stings or a disease infects damaged cells, chemicals are released. chemicals are a group of substances that include prostaglandins, histamine, and bradykinin. These substances promote swelling by forcing blood vessels to leak fluid into the tissues.

During the inflammatory reaction, the following processes occurred:

Redness, swelling, and loss of function are all symptoms of heat.

Inflammation is the body's natural defense system. Damaged cells, irritants, and infections are recognized by the immune system, white blood cell kills the antigen and stimulates the other defense cell to act. this process is called a macrophage.

Answer:

Protozoans → would not have survived because they have no way to produce their own food → Heterotrophs
Algae → would have survived without this food source → Heterotrophs

Explanation:

The protist kingdom is composed of two main groups. The principal difference between them is that algae can produce their own food, while protozoans need to ingest other organisms or organic molecules to survive.

Algaes are autotroph
Protozoans are heterotroph

<u>Protozoans</u>:

Microscopic unicellular organisms, eukaryotic and heterotrophs -predators or detritivores-. Most of them are aquatic free-living organisms, but some species are parasites. They feed on<u> bacteria</u>, other organic wastes, and other microscopic organisms. The phagocytosis process is normally used to ingest the food, invaginating their cell membrane.

<u>Algae</u>:

Eukaryotic micro- or macroscopic organisms. Autotroph and photosynthetic. They might be either unicellular or pluricellular. They use sunlight to synthesize organic matter from water, CO₂, and mineral salts. Unicellular ones can be free-living or associate with others to form colonies. They are part of the phytoplankton and are ingested by heterotrophic organisms. Pluricellular algae do not create real tissues but they compose a tale. The depth at which they inhabit depends on the pigments they produce. All of them inhabit fresh or sea waters.

The correct answer is option C, that is, both vitamin C and zinc are involved in immune system functions.

Vitamin C is an important vitamin, which does an essential function in wound healing, immunity, and eye health. On the other hand, zinc refers to a dietary mineral, which also helps in immunity, protects the eyes from vision-robbing ailments, and also helps to heal wounds.
