labwork [276]

<em>Answer:</em>

  • The increasing order of energy emission is as follow
  •                               Li < Na < K < Rb < Cs

<em>Explanation:</em>

  • The Characteristic colors of alkali metals are
  •                   Li-crimson<em> red</em>
  •                   Na- golden<em> yellow</em>
  •                    K- pale <em>violet</em>
  •                    Rb and Cs- <em>violet</em>
  1. These flame color show that when we moved from down the group, the wavelength decreases (frequency increases).
  2. As the color of Li is red that shows ,it has less emission energy as compare to Rb and Cs that have color violet (more emission energy).

What type of bond is made between amino acids in the ribosome?
sleet_krkn [62]

Answer:

<em><u>Peptide bonds form between the amino group of the amino acid attached to the A-site tRNA and the carboxyl group of the amino acid attached to the P-site tRNA. The formation of each peptide bond is catalyzed by peptidyl transferase, an RNA-based enzyme that is integrated into the 50S ribosomal subunit.</u></em>
