You get home from school and grab a bag of potato chips before settling onto the couch to binge watch your newest Netflix series
. A few hours later, you notice that all of the chips are gone and you feel very thirsty. You get up to go to the bathroom before grabbing a drink and notice your urine is exceptionally dark in color. Apply what you know about osmosis to explain what has happen to the cells in your body. Include the name for the type of solution the cells were in after eating and how the cells attempted to maintain homeostasis despite these salty conditions.
Eating the potato chips created an hypertonic exracellular solution surrounding for the cells within your body.
Explanation:
Potato chips have a lot of salt in them, and the salts from eating a bag of potato chips causes the extracellular fluid in the body to become concentrated with salt (a hypertonic Solution). In response to this, intercellular fluids are ejected to the sorrounding by osmotic movement, to balance out the salt concentration of the fluid outside. This action can lead to some cell shrinking and dying from excess water loss, and that is seen in the dark color of your urine.
Antibiotic resistance is a consequence of evolution via natural selection.
Explanation:
The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this traits to their offspring which will be fully resistant generation
