What are auroras made of?

Biology
1 answer:
bagirrra123 [75]2 years ago
8 0

Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere) due to Earth's magnetic field, where their energy is lost.

The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes.

In a membrane, the________of the phospholipids in one monolayer face the________of the phospholipids in the other monolayer.
matrenka [14]

In a membrane, the tail of the phospholipids in one monolayer face the tail of the phospholipids in the other monolayer.

<h3>What is cell membrane?</h3>
  • The cell membrane is a biological membrane that separates and protects the inside of all cells from the outside environment.
  • It is also known as the plasma membrane (PM), cytoplasmic membrane or plasmalemma (extracellular space).
  • The cell membrane consists of a lipid bilayer, which is made up of two layers of phospholipids interwoven with cholesterol (a lipid component) to maintain  proper membrane fluidity  at different temperatures.
  • Furthermore, membranes are composed of membrane proteins, such as those that cannot be separated across the membrane and function as membrane transporters, and peripheral proteins that simply attach to the  outer membrane of the cell and function as membrane transporters. enzymes to help the cell interact with its environment.
  • The integrated glycolipids of the outer lipid layer perform a similar function.

Natalija [7]
C. Genetic variation

Bacteria are very numerous,  and random mutation of bacterial DNA generates a wide variety of change, including resistance. It happens through mutation and selection. Not only are they capable of sharing genetic bits of DNA to related and unrealted species they can develop ways to remove the antibiotic before it reaches its intended area via biochemical pumps or enzymes to inactiavte the antibiotic.
