Answer:
Diagram, in attachments
Explanation:
From the left side of the screen to the right,that is from a structure with a sugar structure with two other molecules attached to it.
The first molecular structure is Nucleotides. Reasons it contains the middle ribose sugar(5-carbon)connected to the phosphate group and Nitrogenous bases.This is the structure of nucleotides and when this is joined by phosphodiester bond between one a nucleotide, to the phosphate group of another nucleotide molecule it forms a nucleic acid molecule.
The second structure from left to right with long carbon chains, it is a lipid.That js an Ester formed from the reaction of fatty acids with alcohol glycerol.
However, the presence of Phophate group in structure makes it different from a normal tryglycerides.The phosphate group has replaced one of the the three fatty acid molecules.Therefore it is called Phospholipid.With one hydropholic ends(phosphate ends) and the hyrophobic end the carbon chain,with one unsaturated. The lipids molecules are held together my ester bonds.
The next structure is the protein structure(dipeptide).Genrally amino acid is made up of the central Alpha carbon connected on the right by the Carbonyl group(coo-) on the left by the Amine(NH2) group.The R-group which determines the type of amino acids and hyrdogen atom.In the above structure condensation reaction has occurred between the hydrogen atom of the amine group and carbonyl group of the other amino unit to form a dipeptide.The bond formed from the condensation is the peptide bond.
The last structure on the far right are the carbohydrate -ring structure and the straight chains.The functional groups of the CHO -Carbonyl group and hydroxyl group are glues to this.
C: rainforest are biologically more diverse than ecosystems.
Explanation: the reason why this is correct is because of the vast ratio of American and Europeans animal/plant species compared to Brazil alone. They have much more diversity hence having more biodiversity. The vast amount of plants and animals are superior to other countries.
<span>the base sequence of DNA is conserved during replication
through complementary base pairing. The first step of this process is to unwind the DNA's double helix. To do that is necessary the enzyme helicase break the hydrogen bonds between the nucleotides. These results in two strands that can become a template to use for replication. After that the enzyme DNA polymerase will form </span>hydrogen bonds with the nucleotides of the template DNA and new nucleotides, adenine will bond with thymine and
guanine will bond with cytosine.
The replication process has produced a new DNA molecule by using the original strand as a template and the new strand formed which is identical
