why would having both polar and nonpolar properties in a protective boundary be advantageous for the cell?
Reika [66]

Explanation:

The polar nature of the membrane’s surface can attract polar molecules, where they can later be transported through various mechanisms. Also, the non-polar  region of the membrane allows for the movement of small non-polar molecules across the membrane’s interior, while preventing the movement of polar molecules, thus maintaining the cell’s composition of solutes and other substances by limiting their movement.

Further explanation:

Lipids are composed of fatty acids which form the hydrophobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backbone) with up to 36 carbons. Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties i.e. they are amphiphilic. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane.

Answer:

Explanation:

Wave generators harness the power of breaking waves which are disturbances that transmits energy to produce electric power for homes and industries.

This energy source is choice by many because it is environmentally friendly.

Here are some of the disadvantages;

  •  Threats to marine ecosystem especially those organisms that resides on the continental shelf where most these generators are installed.
  • It can pose serious damage to the beach natural outlook as energy waves can be periodically discharged.
  • Disruption of ships and vessels that might dock near the beach.
  • Noise pollution generated by the plant is undesirable.
  • The seasonality of waves might cause fluctuations in power generation.
