The effector of a feedback mechanism is usually which part of the body?
a) skin
b) brain
c) gland
d) stomach

B) brain

Explanation:

Feedback mechanisms are actions capable of controlling the body's homeostasis (balance).

The brain has the main role in these processes, promoting antagonistic actions, dividing into positive and negative feedbacks, such as the increase or decrease in body temperature or blood glucose level, for example.

Positive feedbacks act to amplify actions that promote changes in the body, while negative feedback acts to reverse changes that have occurred. These are more common than the positive ones.

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.
