Common ancestry, hope this helps!
<span>Diffusion. Diffusion is when particles in a highly concentrated area spread out to an area of lower concentration. The membranes of cells are very thin, which allows diffusion of different materials to happen easily.
During respiration, oxygen and glucose concentration in the cell is lower than in the surrounding blood. This causes oxygen and glucose to move into the cell via diffusion. Carbon dioxide is produced inside the cell and this makes the concentration of CO2 higher in the cell than in the blood, so the excess diffuses out of the cell.</span>
Combination of sugar molecules with other elements
Explanation:
A molecule of sugar is basically constructed of carbon, oxygen, and hydrogen atoms linked together as hydrocarbons. This hydrocarbon with C-C bonding facilitates sugar molecules to combine with other atoms and form larger molecules like amino acids, nucleotides etc.
Carbon provides four free valence electrons to share and form covalent bonds with other elements like oxygen, nitrogen, hydrogen etc. Carbon also can link and form long chains of such C-C covalent bond and forms carbon-containing organic compounds.
The carbon, oxygen, hydrogen in sugar molecules combine with nitrogen to form alkaloids and then with sulfur to form amino acids.
Amino acids are the building blocks of proteins which perform various functions as hormones, antibodies, pigments, structural proteins etc and are highly necessary for a living thing to grow and survive.
The answer would be all of the above.
Answer:
True
Explanation:
Hydrophobicity is the aversion to the water of a molecule (or part of it). Amino acids with a hydrophobic R group (glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, and tryptophan) <em>will fold with the R groups in the interior to avoid water. This behavior is one of the most important forces in protein folding. </em>You can see it exemplified in the image I added.
I hope you fidn this information useful and interesting! Good luck!
