Homeostasis
• Keeping the body in balance• If you exercise , your oxygen goes
down,• So your respiratory system
increases (you breathe faster) to bring in O2 and your heart pumps faster to deliver the oxygen
![Page 16: Cells. 1 nucleus- control center using DNA 2 cytoplasm- holds cell water and parts 3 cell membrane- diffusion (oozing) 4 cell wall- protects.](https://reader038.fdocuments.us/reader038/viewer/2022110208/56649dda5503460f94ad1314/html5/thumbnails/16.jpg)
Genetics
• Dominant gene: always shows,• Written with capital letter• Recessive gene: only shows if it is
alone• Written with lower case letter• Co-dominant gene: two genes
there, both show
