1. A genetic mutation causes a disease when the the DNA encodes is altered such that
it no longer functions properly.
2. Errors during can cause genetic problems with the resulting germ cells.
3. Down syndrome is caused by three copies of chromosome 21, also known as 21.
4. A silent mutation is a change in the DNA that does not change the encoded
and has
no phenotypic effect.

(a) scientists could collect and combine data on fish populations all around the world to show that their populations are declining. (b) scientists collect and combine data on fish populations all around the world to show that their populations are increasing. (c) scientists work together and use past data to show that fish populations are becoming locally extinct in some areas.

Astudent sees several ants walking up a wall following the exact same trail that an ant took earlier. she wants to apply the scientific method to determine how the ants detected the trail. which of these steps would come first in her application of the scientific method? perform an experiment by cleaning the scent away from part of the trail. draw a conclusion that the ants follow a scent trail. make a prediction about what the ants will do after she cleans away part of the trail. hypothesize that the ants are following a scent trail that the first ant left.
