Chemists research the interactions of many types of electromagnetic radiation with atoms and molecules. The term "spectroscopy" refers to this interaction.

  • Because various elements have varying quantities of protons and varied numbers and configurations of electrons, they also have different spectra. The variations in spectra are a result of the energy that atoms absorb or emit as their electrons shift between different energy levels.
  • A transition from ground state or lower-energy excited state to a greater excited state can occur as a result of an atom's ability to absorb light of a certain energy. As a result, an element's emission spectrum is converted into an absorption spectrum, which contains dark lines aligned with brilliant lines.
  • Chemists research the interactions of many types of electromagnetic radiation with atoms and molecules. The term "spectroscopy" refers to this interaction.
  • Ordinary stars like the Sun have absorption lines in their spectra because some of the continuous light emanating from the hot, dense interior is absorbed by the fragile outer layers of the stellar atmosphere, known as the photosphere.

valina [46]

Answer: c. Air pollution

Explanation:

There was a heatwave in Europe during the early years of the 21st century that killed tens of thousands across the continent and thousands in France.

Air pollution was blamed for having made the situation worse because the pollutants in the air acted to prevent heat from escaping back into the atmosphere which led to increased heat on ground and therefore a heat wave.

Water's ability to dissolve a wide variety of molecules is important, but more important is the hydrophobic effect, which drives
NeX [460]

Answer and explanation;

The hydrophobic effect is the observed tendency of non-polar substances to aggregate in an aqueous solution and exclude water molecules. Hydrophobic interaction is mostly an entropic effect originating from the disruption of highly dynamic hydrogen bonds between molecules of liquid water by the non-polar solute.

Introduction of such a non-hydrogen bonding surface into water causes disruption of the hydrogen bonding network between water molecules.

Water dissolves molecules (proteins and nucleic acids) that display on their solvent-accessible surfaces groups that can h-bond [hydroxyl, carbonyl, ester groups; they're polar uncharged...also charged groups; protonated amines, carboxylates and phosphate ethers.

Molecules with internal h-bonds dissolve in water, some/all internal h-bonds may be in dynamic exchange with h-bonds in water .

Polar nature of water contributes to ability to dissolve non-ionic polar organic molecules, such as phenols, esters, amides; have large dipole moments and interaction with water dipole promotes solubility in water.

Which of the following represents an important outcome of looping?
frutty [35]

Answer:

a. establishment of left-right asymmetry

Explanation:

  • Cardiac looping is the process in which the heart transforms itself from a straight embryonic heart into a loop that is wounded helically.
  • The looping of the heart takes place on the 23rd day of development.
  • As a result of this looping, there is bending of the cranial portion of the heart to the towards the right end and the caudal portion of the heart towards the left end.
  • At the end of this looping the atrium takes up a dorsal and cranial position and the ventricle is displaced towards left.
  • Thus, the outcome of looping is the establishment of left-right asymmetry.
