The carbon cycle is usually a stable process. Which of the following is a way that humans have disrupted this process and how has that impacted the carbon cycle? Question 6 options:

Humans slash and burn tropical rainforests: This reduces the number of producers taking in carbon from the atmosphere and it also releases carbon back into the atmosphere as the trees burn. The result is more carbon left in the atmosphere

Humans drive cars: They rely on gas which comes from fossil fuels which pulls the carbon from the sedimentary rock. The result is we release the carbon from the rock into the atmosphere that was once trapped deep in the earth.

Poorly managed agriculture: Using more fertilizers, improperly managing the land (poor crop choices, disturbing the soil etc.). The result is more carbon is released from the farmland and put into the atmosphere and there are less plants/trees absorbing the carbon from the atmosphere

Both B and C

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.

Scientists discover two populations of mice on either side of a major river. the two populations have almost identical genes but the mice from one side cannot breed with mice from the other. this is most likely because
