Mycorrhizae, specialized symbiotic associations between the roots of plants and fungi, are characteristic of about 90% of all plants.
Mycorrhizal fungi are a symbiotic combination of fungi and plants. The term mycorrhiza refers to the role of fungi in a plant's rhizome, its root system. Mycorrhizae play an important role in plant nutrition, soil biology, and soil chemistry.
In mycorrhizal organization, the fungus resides in the root tissues of the host plant, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in extrinsic fungi.
The association is sometimes reciprocal. In some species or in specific cases, mycorrhizal fungi may have a parasitic association with the host plant.
Mycorrhizae are generally divided into ectomycorrhizae and endomycorrhizae. These two types are distinguished by the fact that mycelium of mycorrhizal fungi does not penetrate individual root cells while mycelium of endophytic fungi penetrates the cell wall and penetrates the cell membrane.

Answer:
cancer results not from a single flawed gene, but rather the interplay of multiple genes and any accumulated damage to DNA caused by environmental factors such as exposure to chemicals, or aspects of lifestyle, such as smoking
Yes an organ can belong to more than one system because the organ system is the digestive system.
Answer:
The dihybrid proportion for Mendelian example of legacy regularly gives a few deviations attributable to epistasis. One of these proportion incorporate the example of 9:6:1 proportion as opposed to ordinary 9:3:3:1. This proportion can be credited to nearness of copy qualities with total impacts. As per the above model, it very well may be seen that guardians are unadulterated rearing red and sandy in shading. Be that as it may, their offspring show up as red, sandy and curious white pigs in the proportion of 9:6:1 individually.
Explanation:
The information and perception recommend that the qualities liable for red shading and sandy shading are copy in nature and in total, they give sandy shading to the pigs. Be that as it may, nonappearance of any of these alleles in either homozygous or heterozygous condition neglects to produce a coat shading and a vapid white pig is raised. This likewise proposes deviation of Mendelian example of legacy occurs right now to explicit intuitive conduct of these two qualities for red and sandy coat hues. Disappointment of cooperation of these two alleles brings about white pig while nearness of both the alleles results in between allelic association and surprisingly, an extremely enormous number of sandy pigs are watched. Aggregately, it very well may be deciphered that both the qualities are predominant over one another. These alleles produce an alternate phenotype when present alone however produce an impossible to miss phenotype when present together due to between allelic associations. Significantly, it's anything but an instance of essentially added substance conduct of alleles in such a case that it had been, another phenotypic coat shading would have been acquired. Be that as it may, since the F1 offspring resumes the shading like their folks, it speaks to an instance of epistatic copy qualities.
