Answer:
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
Explanation:
B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.
The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.
The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.

Green decade theory helps explain why coverage of ecology issues after the first earth day in 1970 sparked an increase in public concern about the environment.
The concept of green growth is concentrated to assume with economic growth and development can continue while combined with the negative impacts on the environment which include climate change are getting reduced while the natural environment continues to provide services concerned with ecosystem means to decouple.
The critical theory tradition contains the Green theory which makes sense that environmental issues arising out of questions about concerns among ourselves and others in the perspective of community and collective type of decision-making.
Green Growth results in the fostering of economic growth and development conditions while ensuring that the natural assets continue to provide the aspects of productive resources and environmental services where our well-being was settled up.
