The Tate quadrangle occupies an area in northwestern Georgia. The principal industry of the area is the quarrying and finishing of marble. Georgia is the second-largest producer of marble in the U. S. Most of Georgia's marble comes from the small area in the neighborhood of Tate and Marble Hill. The original layers that resulted in the formation of this marble were sedimentary limestone. Marble is a metamorphic rock, not sedimentary. How was the marble eventually formed?

A) Igneous intrusion resulted in contact metamorphism and the production of marble.
B) Run-off and groundwater caused chemical changes to occur in the limestone, resulting in the formation of the metamorphic marble.
C) The limestone underwent folding and faulting during the formation of the Appalachian Mountains, converting it to metamorphic marble.
Eliminate
D) Fossil evidence indicates that layers of sedimentary rock were weighted down and the intense pressure resulted in the metaphoric marble.

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#4

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system—working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
