To test acidity levels of water, scientists test its ph. as acid rain falls, the ph levels in lakes and streams decreases. candice is working on a project to determine whether acid rain is lowering the numbers of bass and mayflies in a lake. she finds the ph of a water sample to be 5.4. she concludes that the lake's ph level is causing a decrease in the numbers of bass and mayflies present there. how would you respond to candice's conclusion, based on the data in the table? a) there is no way to draw a conclusion from this data. b) the statement is debatable; the data does not support that conclusion. c) candice's conclusion is not valid; clam and snail populations would be decreasing. d) candice's conclusion is valid; bass and mayflies begin to die when the ph is below 5.5.

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.

Many farmers prefer cattle without horns because it is safer for their herds. the allele for no horns (n) is dominant to the allele for the presence of horns (n). a farmer mates a male with horns to a heterozygous female without horns. what is the chance that the offspring will have horns?
