Helicases are enzymes. During DNA replication, helicases are important because they SEPARATE double stranded DNA into single strands... allowing each strand to be copied.
Answer:
Dehydration reaction includes removal of water molecule from compounds to facilitate formation of bonds between them while hydrolysis reactions break the compounds by breaking the bonds.
Dehydration reactions form the complex macromolecules while hydrolysis reactions break them down into the simpler elements.
Explanation:
During dehydration reactions, removal of a water molecule from two compounds leads to the formation of a covalent bond between them. These reactions are mainly part of anabolic pathways. Two amino acids are joined together by peptide bond and a water molecule is released during the reaction.
Hydrolysis reactions are the opposite of dehydration reactions and are involved in catabolic pathways of macromolecules. The peptide bonds between amino acids are broken down by hydrolysis.
According to the theory of plate tectonics, _____.
A. the lithosphere is divided into plates
Answer: a molecule made of many small molecules
Explanation: Macromolecules are large molecules that are composed of smaller molecules called monomers. These macromolecules are polymers of the monomers units. Examples of macromolecules are proteins which have amino acids as their monomers and carbohydrates which have monosaccharide sugars such as glucose, and fructose as the monomers.
Plants grow towards the sun due to the chemicals produced inside of their stems.
