Acouple meets with a genetic counselor. the woman's father had sickle-cell anemia, and she and her mother were unaffected. neither the man nor his parents or siblings had sickle-cell anemia. this couple is concerned that their unborn child may be affected with this disease. would amniocentesis be necessary to determine whether the fetus is affected

c. movement because i took the test and it lets me review my answers

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.
