Protists
Protists are unicellular or multicellular microorganisms. The majority of protists are responsible for many diseases in humans.

What structures do all protists have?
The protists do not have much in common besides a relatively simple organization[3] - either they are unicellular, or they are multicellular without specialized tissues. This simple cellular organization distinguishes the protists from other eukaryotes, such as fungi, animals and plants.
Protists live in almost any environment that contains liquid water. Many protists, such as the algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton. Other protists, such as the Kinetoplastids and Apicomplexa are responsible for a range of serious human diseases, such as malaria and sleeping sickness.
Which if the three move the slowest a paramecium amoeba or euglena?
Amoebas move the slowest out of the three organisms (paramecium, amoeba, euglena). They use pseudopods to move and typically glide along surfaces at a slow pace.
What organelle allows some protists to detec light?
The eyespot is the organelle that allows some protists to detect light.
All protists have a nucleus because they are eukaryotic organisms. The presence of a nucleus is a defining characteristic of eukaryotes, which separate them from prokaryotic organisms like bacteria.
Could amoebas live in the water of a swimming pool that's over 26 degrees and cause meningitis?
No, most pools in Arizona are about 32 degrees celsius or 89 degrees Fahrenheit in the summer
Yes, they are because they do not meet the qualifications to be plants, animals,monerans or fungi.
Where can you find protist fuligo?
you can find slime mold (Fuligo) in damp areas, under bridges, forests, in your back yard, etc.
Did Stevens make a Favorite Ladies Model with the number 124 on the lower tang of the receiver?
The Favorite series is composed of many different variations, some only differing in the sights. The #21 Ladies Model is actually quite rare, but is often confused with the #21 Bicycle Rifle. They are marked similarly, but the Ladies Model has a vernier tang sight, high grade walnut stock and a Swiss buttplate. Digital pictures would help. sales@countrygunsmith.net
What is the best diatom filter for aquariums?
The Vortex Diatom Filter is well-regarded for its effectiveness in aquarium filtration. It uses diatomaceous earth to provide fine mechanical filtration, resulting in crystal-clear water and efficient removal of particles and debris. It can be a good choice for maintaining water quality in freshwater and saltwater aquariums.
Yeast can come in little granules or after they flatten it, it becomes a powder.
Some are brown. Like packaged ones are high brown or a little darker brown.
What is the domain of paramecium?
With good vision, you can just make out the speck of a paramecium, since they are about .02 inches (.5 mm) long. They're better viewed under a microscope. Here, you'll see a slipper or kidney shaped cell. Lining the outside of its membrane are tiny, beating hairs called cilia. Cilia move in conjunction, like a line of oars on a ship, to move the paramecium through liquid. The eukaryote is smart enough to navigate around obstacles and towards food.
When a paramecium encounters food, it swivels to move the food into its gullet. The gullet is a small opening, like a mouth. It's lined with other cilia to help "swallow" the bits of organic or decaying matter it eats, like other unicellular organisms or bacteria. The food will continue down the gullet to get stored in food vacuoles until the cell needs energy.
You might be able to make out other rounded structures, called organelles, that sort of function like an animal's organs. Look for contractile vacuoles. The paramecium must keep osmotic equilibrium, which means the water pressure outside its skin and inside its body needs to be equal at all times. Contractile vacuoles pass water from inside the cell to outside, and vice versa.
Following the paramecium as it moves slowly through a viscous liquid, remind yourself that in the wild, out in freshwater ponds, it speeds along at a much quicker pace. Under most circumstances, they reproduce by splitting themselves down the middle and giving each new paramecium half of the organelles. This is called binary fission, and is a simple form of asexual reproduction. If you're lucky enough to see two paramecium meet each other, watch how they behave.

Occasionally, a paramecium will meet another and exchange genetic material during a kind of primitive sexual reproduction. The membranous skins combine to make one giant paramecium. Then the tiny micronuclei that hold all of the genetic material switch around. When it divides into four smaller paramecium, they now have new combinations of DNA.
No... I learned about this in science class like last year...I had the same question
Amoebas are single-celled organisms that lack a fixed shape or structure. They often appear as irregularly shaped blobs that move by extending projections of their cell membrane called pseudopods. Amoebas can be microscopic or visible to the naked eye depending on the species.
Is bacteria a example of a protist?
No,bacteria are not protists.Examples for protists are Algae,Amoeba,Paramecium etc.
What are animalia plantae protista fungi and monera?
the kingdoms of living beings;
animals, plants, protozoa, fungi and ... dunno
How might the classification of protists change in the future?
New classifications of protists are attempting to present monophyletic groups based on structure, biochemistry and genetics.
What type of organisms were first placed in the kingdom Protista?
The kingdom Protista originally included unicellular eukaryotic organisms such as protozoans (e.g., amoebas, paramecia) and algae (e.g., diatoms, seaweeds). The classification has since been revised to reflect the diversity of these organisms more accurately.
