Critical period because they had fully developed their vision
Answer:
As ice melts into water kinetic energy is being added to the particles.This causes them to be "excited" and they break the bonds that hold them together as a solid resulting in a change of state:solid -> liquid.
That's because both H2O molecules and 'glass molecules', more precisely an enormous lattice of silica oxide, are polar. The surface of the glass consists of unsaturated oxygen atoms which can form H- bonding with the water molecules, giving that U shape you are seeing when you put water in a narrow cylinder.
Answer:
a codon can be found on mRNA
Explanation: codons are created when groups of nucleotides are conected to form a animo acid. the formation is all in the mRNA then the animo acids combine to form proteins. proteins are formed when animo acids are "dehydrated" and form a water molecule then the rest combine into a protein and that protein can be in any form for various tasks.
