Read the following scenario and answer the question(s) below.
the formation of sinkholes has become a fairly common phenomenon in the state of florida. most sinkholes are small, but some sinkholes have led to catastrophic property damage and loss of life. one september day in 1999, folks began to notice that lake jackson in the panhandle region was shrinking. within a few days, it was almost gone. a sinkhole had opened beneath the lake and drained it, along with all of the fish and alligators. another sinkhole formed just 10 miles from walt disney world in august 2013, swallowing a 48-unit villa at summer bay resort.
as aquifers lose water, their substrates can become weaker and less capable of supporting overlying strata and any human structures built upon them. in such cases, the land surface above may subside. sometimes subsidence can occur locally and suddenly, in the form of sinkholes, areas where the ground gives way with little warning. once the ground subsides, soil becomes compacted, losing the porosity that enabled it to hold water. recharging a depleted aquifer may therefore become more difficult.
one reasonable way to prevent sinkholes might be to

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

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.
