Answer:

This could mean that the pink ball had a little bit more air in it than the blue ball. They could also have been dropped at the same time, but they were dropped on a hill, and the pink one landed first at the top of the hill, and the blue one landed second at the bottom of the hill.

Sonbull [250]
<h2>Answer:</h2>

The same type of amino acid, means acidic amino acid substitution will leads to normal folding.

The amino acid will be glutamic acid.

<h3>Explanation:</h3>
  • Sometimes the amino acids of the same type substitution leads to normal proteins.
  • As the acidic group of aspartic acid is responsible for the folding of the protein .
  • So if the amino acid is substituted by glutamic acid, it will not leads to any abnormal protein folding.
  • Because glutamic acid also has a acidic group which is responsible for folding of protein.

Substances which will glow in the dark after being exposed to sunlight are called :
mezya [45]

Answer:

D. / 4 - Phosphorescents

Explanation:

Phosphorescence occurs when light is absorved by a material, and when the material is in the dark we can see how radiation is emitted from the object, in the form of light. Phosphorescent materials are called phosphorescents.

Facts/notes:

  • This does not occur immediately
  • It occurs from a longer time than fluorescence (because electrons take longer to slow down their movement)
  • It is a photoluminescence
  • Remember that bioluminescence is not strictly related to phosphorescence. It's a type chemiluminescence.
  • For a more detalied understaning you should read about excitation, types of excitation and how this causes/affects phosphorescence.

Hope it helped,
