My Answer: <span>demographic transition
Hope I helped! :D</span>
A.moves from higher concentration to lower concentration
B. Vitamin B12 and C only. If you just add them up through each column and compare what he is supposed to have to what he gets in the meal then you will see he only meets his recommend B12 for the day and at least 75% of Vitamin C.
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.
<span>1: global warming can harm animals and plants in the ecosystem (even ourselves). global warming is when you litter and throw trash on the ground, and also the more trash that is sent to the dump can cause global warming to get worse. Trash in the ocean can harm animals, they can eat it and get sick, or get it caught on them. It makes our earth become warmer and energy levels change. It can also hurt our atmosphere.
