1 Red algae and green algae include unicellular species, colonial species, and multicellular species. 2  These protists have a special photosynthetic species that are the base of the food web in some habitats. Stramenopiles main characteristic is the flagellum that each protist has. 2  In most protists in this phylum, the hairy flagellum is paired with a short smooth flagellum. o Diatoms: Diatoms are unicellular and are producers of the food chain. 3  These organisms have a cell wall that is made of silica.
Parkinson's disease is a chronic, degenerative neurological disorder that affects one in 100 people over age 60. While the average age at onset is 60, some people are diagnosed at 40 or younger.
Other symptoms include sensory, sleep and emotional problems. Parkinson's disease is more common in older people, with most cases occurring after the age of 50; when it is seen in young adults, it is called young onset PD (YOPD). The main motor symptoms are collectively called parkinsonism, or a parkinsonian syndrome.
