O'Levels Biology Terminology Flashcards

?
Absorption
Movement of digested food molecules through the wall of the intestine into the blood (amino acids and sugars) or lymph (fatty acids and glycerol)
1 of 7
Active Transport
Movement of ions in or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration against a concentration gradient, using energy released during respiration.
2 of 7
Adaptation
Any characteristics of an organism that improves its chances of surviving in its environment.
3 of 7
Aerobic Respiration
Respiration with oxygen. Its the oxidation of food substances in the presence of O2 with the release of a large amount of energy. CO2 and H2O are released as waste products.
4 of 7
AIDS
An abbreviation for Acquired Immune Deficiency S
5 of 7
Alleles
Different forms of a gene which occupy the same relative positions on a pair of homologous chromosomes.
