Important tapeworm parasites of humans Cestoda is a class of phylum platyhyelminthes. The best-known species of this class are called tapeworms. This is a class of parasitic flatworms, their life histories are vary but they mostly live in the digestive tracts or gut of humans and other vertebrates as adult, and sometimes they are present in the bodies of animals as juveniles. All cestodes contain atleast one and often more than one host. They lack digestive tract, mouth and senory organs, they have unique body extension called microtiches which help in absorption of host nutrients.
If a sloth wants to get somewhere fast they just drop from a branch into the water and speed their way down to where ever they were headed. Did you know that the sloth has a whole other ecosystem living in it’s fur. The sloth creates algae in it’s fur do to being unhygienic. Then bugs of all sorts live in the fur. These pests feed off of the algae and are protected by their shaggy
The teeth of a frog are also suited to what the frog eats. The teeth help the frog hold on to the prey to stop the prey from escaping. The respiratory system of an earthworm matches it habitat because the worm breathes through its skin. This is important because the air dissolves on the mucus of their skin so the whole worm needs to dry out for the worm to suffocate instead of just the mouth. The frog breathes through its skin and also has small lungs so the frog can breathe in water and on land.
Common goldfish can grow up to approximately 12 inches in length which is larger than some of the containers the juveniles are kept in. They also produce a good deal of waste as they grow. Fancy varieties usually stay smaller than common goldfish, but their fancy fins are inclined to develop finrot in dirty water. This makes the lack of a filter problematic.
Arthropods have mouthparts adapted for piercing vegetation and sucking out plant juices, whereas Molluscs possess a radula that consists of rows of teeth that enables the animal to scrape algae from surfaces of rocks. Lastly, Arthropods and Molluscs both engage in filter-feeding, although not entirely similar. The bivalve molluscs filter-feed fine particles from the water, and similarly, barnacles from Arthropods also filter-feed with their legs. However, according to Bryant (n.d.), Molluscs such as clams and mussels are internal filter feeders because “they bring in water through one opening (the incurrent siphon), pump it through the filter to remove microscopic food particles, and discharge it through another opening (the excurrent siphon)”. In contrast, Arthropods like Barnacles are external filter feeders, in which no water is pumped through the filter.
This virus is known to be the number one cause of infant diarrhea this virus has been in effect since 1973, and although treatable, Rotavirus attacks mainly young infants and children, due their somewhat weak immune system, therefore many consider the virus deadly and dangerous. Rotavirus is a very contagious virus that causes the stomach and intestines to swell up; adults can also be affected by Rotavirus however the symptoms are not as severe as they are in young children. The symptoms of the virus can take up to two days to show up, they include, watery diarrhea, stomach pain, fever, vomiting, dehydration, and loss of appetite. Due to two of the symptoms being dehydration and diarrhea, many people with Rotavirus must be hospitalized, assuring that the patient receive proper care and fluids their body needs. Since there is no antiviral drug, the patient must drink plenty of liquids and occasionally receive IV fluids as well.
FLA that lived in aquatic ecosystems equipped with flagellates (Ekelund and Ronn, 1994). There are several species of amoeba that lives in the marine ecosystem as consumers and producers but some are known to harbour with symbiotic algae (Gast et al., 2009). FLA is a single living cell with the organelles and cytoplasm are enclosed by a cell membrane with
Nitrobacter when associated with the Nitrosomonas provides it with the nitrite that helps it to obtain energy. Commensalism occurs when one organism alters the environment to make it suitable for the other. Example: Non-pathogenic E.Coli lives in the gut of human colon can grow well outside the colon also. When oxygen is present, the facultative anaerobic E.Coli can use it and even the obligatory anaerobic organisms such as Bacteroids can grow. Thus, anaerobes are benefitted but no such benefits to the
Muskrat Informative Essay Introduction There are a lot of animals in the world, some of them live on land, some live in the sky, some of them live in the water. The animal I will be talking about is the muskrat. The muskrat lives in aquatic areas like wetlands or ponds. They are important to the wetland environment because they eat vegetation and undergrowth in the water. Even though many farmers do not like the muskrat it is still important to our environment.
Pond Ecosystem Investigation Lab report By: Harshal Buradkar 9 grade Introduction A pond ecosystem consists of abiotic: light intensity of the water, depth of the water, and biotic: fish, plants, bacteria, algae, insects and etc. It also contains water and plants which is the most important part of the pond. Ponds are mostly shallow with the depth of 12-15 feet in which the sun rays can touch the bottom of the pond so that plants can grow. My aim is to find out how the plant cover affect the biodiversity of animal life in the pond. Experimental question How does the plant cover affect the biodiversity of animal life in the pond?
Sloths usually only go the forest floor to defecate, this makes them very vulnerable but when in the trees their color, slow movement and the algae on them acts as camouflages. A sloth’s fur is specialized to grow in the away from the sloth’ body to protect it from the weather when the the sloth is upside down and some of the sloth’s fur have tiny cracks that can collect water .Sloths are folivores, they mainly eat leaves and plant material , some two toed sloth sometimes will eat insects and other small animals. Since sloths mainly eat leaves, it does not give them enough nutrients they need so they have specialized chambered stomachs to slowly digest their food. Sloths also have very low metabolic rates and they have low body temperatures. Researchers have found out that sloths in the wild actually sleep about 10 hours a day and don’t sleep for fifteen or more hours like captive
The Bilby, before European settlement where widely spread over around 70% of the Australian mainland than reduced to extinction in some states of Australia due to habitat loss and competition and predation from many introduced species. Through many reintroduction programs across Australia there population has now raised. The Greater Bilby is a nocturnal bandicoot, the largest of the family of marsupials. They have an excellent sense of smell and sharp hearing which they rely on as they have poor vision. Bilbies are omnivores, they eat things such as seeds, spiders, insects and their larvae, bulbs, fruit, fungi and small animals.
In WORMS, we also find a little bit of ourselves, particularly the worm, Amphioxus. Although Amphioxus is an invertebrate, it surprisingly has a nerve cord that runs along its back, and in addition to the cord, the worm also has a rod that runs parallel to it called the notochord. Crazily, human embryos also have a notochord. “Your Inner Fish” is like an animalistic Ancestory.com, and the further we dive into its contents, the crazier the connections get. As Neil says, “the essences of our heads goes back to worms, organisms that do not even have a head” (Shubin 96).
Although the worms extract the nutrients from the whale bones, scientists did not know how, due to their lack of “body parts for physically drilling into the hard material” and absence of a mouth and gut (Ennis). Instead, it turns out, the worms have special root-like structures that attaches to the bones and dispenses an acid that dissolves the whale bones and extracts the nutrients. Although, the zombie worm is not the only interesting deep sea creacher. The deep sea jellyfish for example, are just as fascinating as the zombie worms. They live about 820 meters below the surface of the ocean (Jonssen).
