Ayuda con la tarea de biología
La parte más complicada de aprender biología es cómo hacer que los estudiantes comprendan el mundo microscópico de la biología, cómo entrar en las células y explorar genes y moléculas. Sin embargo, con el desarrollo de la tecnología de la información, la ayuda con la tarea de biología puede desempeñar un papel importante cuando ni las palabras ni las imágenes pueden explicar completamente los puntos de biología.
QuestionAI es un software de aprendizaje de biología en línea que le ayuda a aprender y dominar el conocimiento de la biología, incluida una variedad de experimentos y ejercicios correspondientes, que es fundamentalmente diferente del ayudante común de preguntas de biología. Aquí, puede simular experimentos para reproducir los escenarios experimentales, de superficial a profundo, capa por capa, para aprender y comprender los puntos de conocimiento.
- Passages uresuyatuk uopes of hyphae) connect the foundation tree with other trees-like an express stop on a subway system where lots of local trains come through-and the bigger the tree, the larger the hub. That's because the largest trees have the greatest root system, and the more roots there are, the more real estate there is for the fungus to colonize -In one forest, we found 47 trees linked by two species of fungi composed of 12 individuals," said Simard. (B)individuals, shemeans two genetically distinct fungal entities.) "Talk about two degrees of separation!" Even nonphotosynthesizing plants take advantage of "the hub:"Parasites like the Indian pipe depend totally on mycorrhizal fungi for its nutritive needs. It taps into the nutrients and water provided by the mycorrhizae and connects via the mycorrhizae to a photosynthesizing plant for sugar. Despite the fact that fungi are microscopic organisms the functions they perform are often on an ecosystem or landscape scale. Ifyou could take an x-ray look at the soil, you'd see that underneath the forest duff there is a layer of mycorrhizal mycellum running between, on, and in the roots of plants.It's like a stratum of life between the duff and the soll that holds water and nutrients in the ground. And when that stratumis disrupted,or not present, plants suffer. In fact.ecosystems with inadequate mycomtizal fungican experience catastrophic losses of plant biomass. Which of the following statements, if true, would most WEAKEN the claim made by the author in the highlighted lines of the passage? F Overa three-year span.two forests with different tree types increase the amount of I'mycorrhizal mycellum at the same rate. G mycorthizal mycellum bothlost the majority of their plant Over a three-year span, two forests with the same amount of biomass. H Duringagivenyear, after the majority of mycorrhizal mycellum diesina forest the plants in the forests flourish.

Muscle's ability to respond to stimuli from motor neutrons or external sources. 15. Muscle's ability to return to its original shape. 16.Muscle's ability to be stretched without tearing.
- NATURAL SCIENCE: This passage is adapted from the book Mycophilla: Revelations from the Weird World of Mushrooms by Eugenia Bone (62011 by Eugenia Bone). There are a number of fungi that live in mutualist relationships in which a balance of interests occurs between two organisms.Lichen has a mutualistic relationship with photosynthesizing algae and bacteria. And there are also commensal relationships, where the fungus may not be doing the host any good or any harm.either-the raison d'étre of some yeasts in our body, for example, is unknown and may be commensal. But mycorrhizal fungi are the princes of mutualism. "Fung!can't make their own food," said Gary Lincoff "So they made a strategic choice to team up with plants." Ninety percent of natural land plants are thought to have mycorrhizal fungi partners. It's a masterpiece of evolution: Mycorrhizal fungi break down nutrients like phosphorus, carbon water, and nitrogen into a readily assimilative form and deliver them to the plant in return for sugar produced by the plant via photosynthesis. The fungus needs sugar for energy and to launch its spores, and the tree needs nutrients because (despite what Ilearned in school) tree roots don't do the job adequately. Tree roots primarily anchor the tree in the soil. While tree roots will absorb moisture if watered and nutrients if fertilized, it is the mycorrhizal fungus growing on and in the tree roots that provides the tree with the lion's share of it:nutrition and water. Mycorrhiza fungisignificantly expand the reach of The author most likely includes the quote from Lincoff (highlighted) to: F suggest that mycorrhizal fung have a commensal relationship F with plants. G contend that mycorrhizal fung serve the same function as some yeasts in the human body. H indicate why mycorrhizal fung have a mutualist relationship with plants. J explain why mycorrhizal fung cannot make their own food.
- Choose the type of muscle tissue that is being described below. Each type of muscle will be used several times. a. Cardiac Muscle c. Smooth Muscle b. Skeletal Muscle 17. Cells in this type of tissue appear branched and formed connections with one another. 18. Function is movement of bones and other body structures. 19. Tissue only found in the myocardium of the heart. 20. The only type of muscle tissue that is voluntary. 21.Found in the walls of hallow organs in the body (Ex. digestive tract, urinary tract, arteries). 22. The type of tissue that biceps brachii, triceps brachii, and deltoid muscles are made up of. 23. Type of muscle that does not appear with striations. 24. Most common type of muscle tissue in the body (over 600 of this type of muscle present in the body).
- Passages And multiple fungi can colonize the roots of all or most of the trees in a forest. The hyphae, those threadlike strings of cells that are the fungus, function as pathways for shuttling nutrients water, and organic compounds around the forest. The mycologist Paul Stamets believes that mycorrhizal fungi function as a giant communications network between multiple trees in a forest-he calls it "nature's Internet." Others have described this linkage as the "architecture of the wood wide web." Weaker plants areable to tap into this network, too, like hitchhikers on a nutritional superhighway . Young seedlings struggling to grow in the shadow of established trees tap into the larger, older tree's fungal network to improve their nutritional uptake. This network exists to benefit not only established trees and seedlings of the same species but also trees from different species and at different stages of development. So one multitasking fungus, its hyphae attached to the roots of multiple trees in the forest, can simultaneously provide a different nutritional load as needed to different trees. It's a couture service. The old trees in a forest function as hubs for these mycellal networks."like spokes of a wheel; said Suzanne Simard, a professor of forestry at the University of British Columbia who studies mycorrhizae. Rhizomorphs tropes of hyphae)connect the foundation tree withother trees-like an express stop on a subway system where lots of local trains come through-and the bigger the tree the larger the hub That's because the largest trees have the greatest root system, and the more roots there are the more realestate there is for the fungus to colonize. "In one The main idea of the fourth paragraph (highlighted)is that: A networks of fungi benefit different species of trees at various A levels of development. B young seedings typically tap into the roots of trees that are the same species as the seedlings. C established trees genetically alter fungal networks to benefit different species of trees. different species of trees can be identified based on their nutritinnalintake
