Alexis just completed the osmosis egg lab. on day one, egg 1 and egg 2 were soaked in vinegar for twenty-four hours to remove the shell. on day two, egg 1 was soaked in corn syrup for 24 hours and egg 2 was soaked in water for 24 hours. on day three, alexis recorded her observations in the observation data table shown below. 1. based on alexis' observations, the corn syrup is what type of solution? a hypertonic b hypotonic c isotonic d solution 2. based on alexis' observations, the water is what type of solution? a hypertonic b hypotonic c isotonic d solution

1.a

2.b

explanation for answer 1: The egg became smaller due to the fact water traveled out off the egg since the egg is hypotonic to the corn syrup. you can remember this by how people are hyper to go to recess like how water is "hyper" to leave a densely packed solution of water.

explanation for answer 2: The egg became bigger since the water went into the cell since the egg was hypertonic to the solution. You can remember this by when your hyper you explode with energy just like how a cell will explode when there is to much water in a solution.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
