GIVING BRAINLIEST! In the 1940s, American farmers lost 7% of their crops to pests. By the 1990s crop losses due to pests had risen to 13%. Select a reason for this increase.

A. Between the 1940s and 1990s more land was being developed for houses and city space. Less land was used to grow crops. The increased number of crops in smaller spaces led to increased numbers of pests.

B. The farmers were using reasonably effective pesticides in the 1940s. However, over time, more pests have evolved to become more resistant to the pesticides.

C. The pesticides decreased in quality due to America's expanding economy, allowing more pests to successfully feed on the crops.

D. Pests became used to the taste of pesticides and were able to detect when crops had been sprayed.

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.

Based on the data in your tables, did the light-colored moths have a higher or lower survival rate after the industrial revolution?

Cattle with brown fur and cattle with white fur will produce a reddish roan calf . when examined closely, the calf show about an even number of brown hairs and white hairs that give a reddish appearance when viewed from far away. the fact that both the brown fur allele and the white fur allele are expressed equally in the offspring is an example of
