Answer:
A. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell

Some of the skateboarder’s stored chemical energy is being used to fuel muscle movement. This movement would also involve a release of thermal energy by the skateboarder.
False.
Injuries or destruction on the spinal cord below the C5 region do not affect the well-functioning of the diaphragm. When they occur close, like in C6 region, may cause some weakening in breathing but won't ever paralyse the diaphragm completely.
Answer:
water is essential for life as we know
Explanation:
Water (H2O) is essential for life (i.e. carbon-based life) because this molecule has unique chemical properties. First, water is a universal solvent that helps cells to transport and use essential molecules (e.g., oxygen and nutrients). Second, water molecules help cells to maintain their shape/structure by generating pressure within the cells. Third, the polarity of water helps the formation of phospholipidic membranes because phospholipids have polar heads that interact with water and nonpolar tails that interact with each other. Fourth, water has a high heat capacity, thereby helping to regulate the temperature in the (intracellular) environment. Finally, water molecules also have unique adhesion and cohesion properties that enable the movement of substances against gravity (adhesion) and create a surface tension (cohesion) that helps to the formation of bubbles with water.
