Hydrogen bonds<span> are much weaker than covalent bond because of its bond is formed through fundamentally electrostatic interactions.
Hydrogen bonds happen due to dipole-dipole attraction while covalent bonds happen when valence electrons are shared.
Reasons why complementary nucleotides across the double-stranded dna bond together using hydrogen bonds rather than covalent bonds are (1) the distance between two strands, (2) size of the bases, (3) geometry of each base.</span>
Answer:
All are methods to separate mixtures
Explanation:
<em>A mixture consists of 2 or more substances that are mixed physically but not chemically. Hence, mixtures can be separated by any physical separation means which include but not limited to filtration, distillation, sieving, magnetization, and evaporation.</em>
Filtration is usually used to separate suspended particles in a liquid using a membrane of a filter paper. Distillation is used to separate miscible liquids with varying boiling points by evaporating and condensing them back at their respective boiling points. Sieving is used to separate mixtures with varying particle sizes of individual components.
Magnetization is usually used to separate mixtures with, at least, one component with magnetic property. Evaporation is used to separate dissolved solids from liquids.
<u>Hence, all the methods listed are used to separate mixtures.</u>
Ok so I'm gonna name and letter everything

Sorry if this is confusing or wrong.....
I know this might sound like a dumb answer but it could be your answer <span>They are both very hot</span>
