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.

How is the range of a data set determined?
Makovka662 [10]

Answer:

D

Largest value minus the smallest value

Explanation:

The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

Messenger RNA: is found only in the cytoplasm. is the most abundant form of RNA. in all cells is initially formed as a large pre
eimsori [14]
<h2>Messenger RNA</h2>

Explanation:

  • Messenger RNA (mRNA) is a solitary stranded RNA atom that relates to the hereditary arrangement of a quality and is read  by the ribosome during the time spent creating a protein
  • The three most significant strides of pre-mRNA processing are the expansion of settling and <em>signaling factors at the 5′ and 3′  ends of the molecule,</em> and the expulsion of mediating arrangements that don't indicate the <em>proper amino acids. </em>the mRNA <em>transcript can be “edited”</em>  after it is transcribed.
  • During transcription the RNA polymerase read the layout DNA strand the <em>3′→5′ way, however the mRNA is shaped in the 5′ to 3′  direction. </em>
  • The essential capacity of mRNA is to go about as a intermediary between the <em>hereditary data in DNA</em> and the amino acid sequence of proteins.
