A statistic used in the fields of breeding and genetics that estimates the degree of variation in a phenotypic trait in a population that is due to genetic variation between individuals in that population.
Answer: C. The orchids receive water and oxygen from the fungi, while the fungi receive food and minerals from the orchids.
Mycorrhizal association refers to the mutualistic symbiotic relationship between a fungi and roots of vascular plants. In this type association both partners are benefited.
The plant roots are unable to take nutrients which are chemically or physically immobilized in the soil. The mycelium of the mycorrhizal fungus helps to avail those nutrients to the plants. Thus plants are able to obtain phosphates and iron through these fungi. These fungi also, increase the water absorption capacity of plants. In return the fungi receives the direct access of carbohydrates like glucose and sucrose. These carbohydrates translocate from leaves to roots, from there fungi receives these carbohydrates as food source.
The plant orchid and fungi of phyllum basidiomycota form mycorrhizal association, which is a mutalistic association. Thus, the orchids receive water and oxygen from the fungi, while the fungi receive food and minerals from the orchids.

Answer:
Each organism lives in different environments to enable it to survive. All animals from different species have different traits that helps them survive in their environment. And because some animals have many variations of traits in their gene pool it can help them adapt to the changes in their environment.
The correct answer should be B. You can rule out C because, to be honest, does not make sense. You can also rule out D because rocks can go through the rock cycle many different ways. Lastly, you can rule out A because rocks move around alot during the rock cycle, making it so that they do not stay in the same place.
