A scientists follows this procedure to test wether plants have been performing photosynthesis.
1.place plant X in a dark closet and plant Y on a sunny windowsill
2.wait several days, then remove a leaf from each plant
3.boil leaves in alcohol to remove the chlorophyll
4.add chemical indicator that detects sugars(dark purple=sugars are present ;dark orange=sugars are not present

What results will the scientist most likely obtain when placing drops of the indicator on the leaves?
A- plant X dark purple. Plant Y dark purple
B- plant X dark purple. Plant Y dark orange
C- plant X dark orange. Plant Y dark orange
D- plant X dark purple. Plant Y dark orange

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.
