Pls answer Use the canopy figures 4, 5 and 6 to answer the following questions:
a. Which tree species disappeared between 20 and 50 years after the field was abandoned?
b. What tree species appeared between 20 and 50 years after the field was abandoned?

**Think about the types of trees growing after 20 years in the understory. Are they tall or short species? Now think about the types of trees growing after 50 years. Are they tall or short species?

**Based on your answers to questions 3 and 4, what caused the change in the air and soil temperature between 20 and 50 years after the field was abandoned?

*Did certain species of trees decrease or disappear during succession? Discuss what factors and conditions may be related to these changes.

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses.cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown.cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan.cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan.select the correct statements regarding the mode of inheritance of the coat color genes.a) both genes are x-linked.b) both genes are autosomal.c) one of the genes modifies the expression of the other gene.d) each gene has an additive effect on the intensity of coat color.e) each gene independently specifies three colors.f) one of the genes is autosomal, and the other is x-linked.
