What is the function of a circulatory system? a) it brings a transport liquid into close contact with all cells in the body. b) it exchanges oxygen and carbon dioxide with the outside air. c) it is the site of blood cell production. d) it acts as a reservoir for the storage of blood.

The correct answer is a) It brings a transport liquid into close contact with all cells in the body.

Explanation:

The circulatory system helps in bringing the blood which is a transport liquid in close contact with the cells present in our body. This helps in gas exchange between cells and blood. The circulation of blood in the body occurs by the pumping of blood by the heart into arteries, veins, and capillaries.

This circulation of blood plays many other vital functions like transport of nutrients to the cells, transport of waste products from the cell to outside the body, transport of hormones, maintenance of body temperature, etc.  

So all these processes become possible when transport liquid comes in contact with the cells. Therefore the right answer is a.

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
