In a study conducted at virginia tech on the development of ectomycorrhizal, a symbiotic relationship between the roots of trees and a fungus, in which minerals are transferred from the fungus to the trees and sugars from the trees to the fungus, 20 northern red oak seedlings exposed to the fungus pisolithus tinctorus were grown in a greenhouse. all seedlings were planted in the same type of soil and received the same amount of sunshine and water. half received no nitrogen at planting time, to serve as a control, and the other half received 368 ppm of nitrogen in the form nano3. the stem weights, in grams, at the end of 140 days were recorded as follows:

Chapter 11.1 & 11.2 notes section 11.1 1. every living thing has a set of ? inherited from its parents. 2. after becoming a ? , mendel spent several years studying ? and mathematics at the university of vienna. 3. during sexual reproduction, male and female reproductive cells join, a process known as ? . 4. pea flowers are normally ? , which means that sperm cells in pollen fertilize the egg cells in the ? flowers. 5. when mendel crossed plants with ? characters for the same trait, the resulting offspring had only one of the characters. 6. a ? is a specific characteristic, such as seed color or plant height, that varies from one individual to another. 7. filius and filia are the latin words for ? and ? . 8. the offspring of crosses between parents with different traits are called ? . 9.to mendel's surprise, all of the offspring had the character of only ? of the parents. 10. mendel's first conclusion was that biological inheritance is determined by ? that are ? from one generation to the next. 11. scientist calls the chemical factors that determine traits ? . 12. mendel's second conclusion is the ? . 13. the principle of dominance states that some alleles are ? and others are ? . 14. when mendel allowed the f1 plants to reproduce by self-pollination the traits controlled by ? alleles reappeared in about ? of the f2 plants in each cross.
