Protists

An example of a protist species that obtains nutrition by external digestion is the parasitic protist Plasmodium, which causes malaria in humans. Plasmodium infects red blood cells and digests hemoglobin to obtain nutrients.

To measure the length and width of a paramecium in microns using a 40x magnification microscope, you can use a calibrated eyepiece graticule or stage micrometer to determine the field of view in microns at that magnification. Then, you can measure the paramecium by counting the number of microns it spans across using the field of view as a reference. This will allow you to estimate the length and width of the paramecium in microns.

Algae provides essential nutrients like oxygen and food to various creatures in aquatic ecosystems. It forms the base of the food chain, being a source of energy for many marine organisms such as small fish, shrimp, and other aquatic animals. Algae also plays a crucial role in maintaining oxygen levels in water bodies, supporting the overall health of ecosystems.

The organism Paramecium moves with the help of hair-like structures called cilia and has a rigid outer covering known as a pellicle. The pellicle provides support and protection to the cell membrane of the Paramecium.

you could try twenga, they seem to have alot of great deals on at the minute and have a wide stock of produce so you should give it a go?

-- previous poster, perhaps an employee of twenga? Diatom Dust XR is merely a trade name. I just bought some from Tallman Scientific, is bulk freshwater diatomaceous earth repackaged in a ziploc bag and taped up with clear tape and a home-printed label. But I presume it is actual diatomaceous earth, which is also available, in similar repackaged form, in many places on the Internet, though not, apparently, anywhere in New York City retail stores. They make it sound so flashy, and if you get it from them the "bed bug barrier tape" is simply double-sided duck tape. I tried putting diatom dust xr on top of it, which they don't talk about, but we'll see how I fare. I think, touch wood, that I'm winning the battle so far.

Good luck

Blooms of certain dinoflagellates are associated with all of the following: red tides, harmful algal blooms (HABs), production of toxins, and increased water turbidity.

Plasmodium gets into mosquitoes when they feed on the blood of a human or animal infected with the parasite. The parasite enters the mosquito's digestive system and moves to its salivary glands, where it can be passed on to another host during a subsequent blood meal.

According to many labels on most algicides, you don't have to wait. Actually from the pool guy at the pool store, it will help to mix in the algicide. Just be sure to take a shower when you are done swimming, and make sure you are not allergic to any of the ingredients before you swim.

Yes, amoebas move by extending cytoplasmic projections called pseudopods. They engulf their prey through a process called phagocytosis, where they surround and internalize the food particles into their cell bodies.

Yes.

Paramecium are known to increase their speed of movement and arousal levels and agitation is increased.

Paramecium also will move within warmer temperatures comfortably and even more towards warmer temps.

It is the other way around. Consider that when any one cubic meter of Ocean bottom is obtained [to be sampled] - in any Ocean and at any depth - one cubic meter of Bacteria is obtained.

Photosynthetic organisms such as blue-green algae, diatoms and phytoplankton need primarily - aside from a few minerals - CO2 and (En) Sunlight; both mostly available at the Ocean's surface.

Dinoflagellates spin to move through the water and to orient themselves towards light for photosynthesis. The spinning motion helps them to navigate their environment efficiently and to capture light for energy production.

Yes protists are facinating and can live in almost every single biome in the world. All except for Antarctica

Hermit crabs fight by using their claws to pinch and grab each other. They may also use their shell as protection and shelter during fights. The goal of the fight is often to establish dominance or access to resources such as food or mates.

The sporozoan Plasmodium causes malaria, a potentially life-threatening disease transmitted through the bites of infected mosquitoes. It infects red blood cells and can lead to symptoms such as fever, chills, and flu-like symptoms. If left untreated, malaria can be fatal.

Plasmodium vivax is a protozoan parasite that infects red blood cells. It has a ring stage and mature stage with amoeboid morphology. It can be identified under a microscope by its characteristic appearance within red blood cells.

A prophage is made up of proteins that replicate a virus within a cellular structure. The virus does not disrupt the cellular structure of the bacteria, and waits for the lytic cycle to begin so it can replicate.

The organism responsible for the presence of amoebae in cerebrospinal fluid is likely Naegleria fowleri, a free-living amoeba that can cause a rare but severe infection of the brain called primary amebic meningoencephalitis (PAM). Infection typically occurs when contaminated water is inhaled through the nose, allowing the amoeba to enter the brain. Early identification and treatment are crucial as PAM can be fatal.

The red tide is caused by a type of protist called dinoflagellates, particularly species from the genera Karenia and Alexandrium. These protists produce toxins that can harm marine organisms and affect human health when accumulated in shellfish.

A paramecium will typically swim away or around the cotton fiber using its cilia to sense and navigate its surroundings. It may also secrete enzymes to try and break down the fiber if it perceives it as a potential food source.

The larger nucleus in Paramecium is called the macronucleus, which is responsible for general cell functions like metabolism, growth, and reproduction. The smaller nucleus is called the micronucleus, which is involved in genetic variation through processes like conjugation and genetic exchange.

Paramecium have a rigid outer covering called a pellicle that limits their ability to change shape. Amebas, on the other hand, have a more flexible cell membrane that allows them to change shape easily in order to move and feed.

The indentation in a paramecium where food is taken in is called the oral groove. It is lined with cilia that help sweep food particles into the cell. Once food is captured in the oral groove, it is enclosed in a food vacuole for digestion.

Amoebae is an eukaryote protist.
