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.
Explanation:
Melanin is the pigment which absorbs UV light and it is present in skin and gives black colour to it.As we can see africans usually have black skin as they have to face direct uv light.
If the lizard was a less desirable female/male in a time where their gender outnumbered the other and therefore not all of them get a mate.
<u>Answer</u>: Hybridization.
Hybridization is the process through which two species can mate with each other and produce fertile offspring thus creating a new species.
This is not happening with the two palm species on the island. This may be due to prezygotic barriers that prevent these two species from mating and producing a zygote (fertilized egg cell). In essence these barriers prevent any gene flow between the two species.
