Can someone me with this ? > > analyze the structure in the diagram and explain how living systems use this structure. be sure to include the following points in your 1) a description of the important properties of the structure in the diagram. 2) an explanation of how the structure functions in the cell. 3) an explanation of how the structure regulate materials in living systems. 4) a prediction of how water will move from one side of the structure to the other side.

The structure is of lipid bilayer or phospholipid bilayer found in cell or plasma membrane.

Explanation:

a) The most important property of lipid bilayer is that it is highly impermeable and does not allow molecules except gases and water through it unless integral proteins or ion channel comes in the action.

b) There are receptors and ion channels on the cell membrane that allow only specific exchange of ions, gases, nutrients, metabolites between cellular and extracellular environment.

c) The phospholipid bilayer has specific integral and peripheral proteins, ion channels which regulate the materials in cells.

d) The bilayer of lipid is arranged such that it has hydrophilic heads of phosphate group and hydrophobic tail of fatty acid. The water is a small molecule diffuses through protein channels also the osmotic pressure difference leads to movement of water in the cell.

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.
