Term | Definition |
lipids | store energy and include fats, oils, and waxes made from fatty acids and glycerol |
carbohydrates | are sugars and starches made from simple sugars and supply energy |
differentiate | start to form different types of cells. at this stage the embryo is very vulnerable to alcohol, drugs, etc... because the important organs and systems are just starting to develop |
specialization/differentation | this occurs when only some genes in the nucleas of a cell are "turned on" |
controlled experiment | compares the results of an experiment between 2 or more groups |
chromosome pairs | carry alleles for the same trait. We all have 2 alleles for each gene-1 from each parent-1 on each member of the homologous pair |
the cell membrane | is made of lipids proteins. it shows selective permeability- that is only some molecules can pass through it (typically small molecules like water and oxygen) large molecules (like starch or protein) need to be moved by active transport |
plasma | the fluid of the blood. transports everything except oxygen. |
proteins | are made from amino acids, also make hormomnes and many body and cell structures |
respiration | organisms get energy by breaking the bonds of sugar molecules. The released energy is used to make a molecule of ATP, which gives all organisms their energy |
pancreas | makes insulin and glucogen which control blood sugar |
aerobic restoration | requires oxygen and yeilds more ATP (energy) for a molecule of sugar than anaerobic (no oxygen) respiration. |
regulation | coordination and control of other life functions |
alveoli | very important because it is here that the oxygen enters the blood and CO2 leaves |
stimulus | a change in the environment that you respond to. |
respiratory system | physical respiration provides oxygen needed for chemical respiration. |
