Remember that the glomerulus is the initial filtering sieve of the nephron.
know that the glomerular filtration rate (gfr) for all of the nephrons in both kidneys is approximately 125ml per minute. that means that about 125ml of fluid and dissolved substances are filtered out of the blood per minute. the fluid moves into the bowman’s capsule, the first collecting tube of the nephron. use this information to complete the calculations and answer the questions below.
o calculate the gfr per day. show your work. express your answer in liters (l) per day.
o about how many 2l soda bottles would you fill per day?

o what do you think about this value? do you produce this much urine in one day? what must be happening to some of the fluid that is being filtered by the glomerulus?

o if the first part of nephron action is called filtration, what name do you think is given to the second part of the process, where precious water is returned back into the blood?

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.
