Please look at the 5 scenarios below, 1st you need to determine if they are positive or negative feed back loops. then, you need to defend your answer! Please use complete sentence when explaining your answer! An increase in concentration of glucose in the blood stimulates the pancreas to secrete insulin. This is an example of (negative/positive) feedback.
The onset of contractions during childbirth causes the release of oxytocin which stimulates further contractions of the uterus. This is an example of (negative/positive) feedback.
Thyroxine levels are low causing the pituitary gland to release thyroid stimulating hormone, which stimulates the thyroid to release more thyroxine. This is an example of (negative/positive) feedback.
Water concentration in the blood stream is low causing the release of antidiuretic hormone which causes the body to hold water and not release it as urine. This is an example of (negative/positive) feedback.
Suckling stimulates the release of oxytocin which causes milk letdown from mammary glands, which stimulates more suckling, causing the release of more oxytocin resulting in increased milk letdown. This is an example of (negative/positive) feedback.

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.
