During the life cycle of a beef tapeworm, a human becomes the primary host.
Variation within the human population refers to the differences in traits such as height, skin color, and blood type that exist among individuals. This variation is influenced by genetic factors, environmental factors, and interactions between the two. It is what allows humans to adapt to different environments and thrive in diverse conditions.
Taenia solium, a tapeworm, reproduces by self-fertilization within the intestines of its definitive host, typically a human. The adult tapeworm releases eggs, which are then passed in the host's feces. These eggs can infect intermediate hosts, such as pigs, completing the life cycle when the infected meat is consumed by a human.
No. ----------------------------------------parasitism the worm takes all the nutrients The dog does not benefit but the tapeworm does. The tapeworm steals nutrition from the dog and provides no benefit in return. In this case the dog can die from no nutrition
A biome can change due to factors such as climate change, natural disasters, human activities like deforestation or urbanization, and shifts in species populations. These changes can alter the environmental conditions within a biome, leading to shifts in the types of plants and animals that can thrive there.
Tapeworm infections can lead to diarrhea, but the duration varies among individuals. Symptoms can last from a few days to several weeks, depending on factors like the person's immune response and the severity of the infection. Treatment with antiparasitic medications typically resolves the infection and alleviates symptoms within a few days. However, if left untreated, diarrhea can persist as long as the tapeworm remains in the host.
According to the researchers, the ancestors of the human species first got infected by tapeworms when they began consuming more of the worm-infested meat as hyenas and big cats did. They go on further to say that these studies are the first to connect human tapeworm infestations with increased scavenging of meat and hunting by human beings. Both humans and animals ingest newborn tapeworms regularly. The embryos of the tapeworm are ingested either by direct contact with infected feces, or by drinking contaminated water, or by eating the flesh of animals infected with tapeworm. For humans who have tapeworm infection, the parasite is the most dangerous when it is at the embryo stage, because an insidious infection called cysticercosis can develop. http://www.buzzle.com/articles/human-tapeworm-intestinal-parasite-infection.html
An example of a parasitic symbiotic relationship is a human and a tapeworm. The tapeworm gets nutrients and fat and all that from the food and the human is deprived of the food's nutrients.
