The answer is “dinoflagellates”.
Dinoflagellates are a group single celled eukaryotes from the kingdom Protista. Dinoflagellates are often photosynthetic and can produce their own food by photosynthesis. Some dinoflagellates are parasitic. When there is a large number of dinoflagellates during the warmer seasons (also known as an “algal bloom”), the body of water will change into a rusty red color called red tide. Red tide occurs because dinoflagellates produce a neurotoxin called saxitoxin which manifests as paralysis. When humans eat affected fish, they will experience a non-specific syndrome with nausea and vomiting called ciguatera. On the other hand, when humans eat affected shellfish; then there will be paralysis, confusion, poor mental status, etc. and this is called paralytic shellfish poisoning.
Answer:
The co-ordinate efficiently and effective...
Explanation:
Well...it is a type of antagonistic mechanism based of Dalton's Law for PArtial Pressures. We take in O2 and Exhale CO2 very effectively because the partial pressure of oxygen is higher outside and lower inside lungs and vice versa for CO2. when the Air with 21% O2 content enter the lungs, the Alveoli that are special sacs filled with air absorb some of it through their membranes and by a process called membrane diffusion of gases. The Air with 16% O2 content is exhaled out by the antagonistic action of lungs and Diaphram muscles combined.
Composed of Veins
Or you can also use both Veins and arteries

Law of Magnetism. The most basic law of magnetism is that like poles repel one another and unlike poles attract each other; this can easily be seen by attempting to place like poles of two magnets together.
