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.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
