The image below depicts a bowling ball traveling down the lane and striking pins, knocking them down. Describe the effects on the bowling ball's motion of the some of the forces acting on the ball. Choose all that apply.

1. Friction acts in the opposite direction of balls motion
(a push.)

2. Gravity pulls the bowling ball ‘down’ that is, towards the center of the earth.

3. Density makes the ball move.

4. Inertia makes the ball sit still until a force is applied.

5. The person who let the bowling ball go applied a force or a push to the ball.

Approximately 90% of all cases of polycystic kidney disease are inherited in an autosomal dominant fashion. the disease is typically related to mutations to genes (pkd1 and pkd2). pkd genes can be found on chromosome 16. the disease occurs in approximately 1: 800 to 1: 1000 people. here is a hypothetical example. the dominant allele d will cause the development of pkd. the recessive allele is known as d. what genotypes would correspond to suffering from pkd? dd, dd what genotypes would correspond to being normal (not suffering from pkd)? dd consider that 1: 1,000 people have pkd in your population of 325million. consider that pkd is inherited in an autosomal dominant fashion. show you math for all of the following questions: what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is p? what is q? how many people in your population would have pkd?

What environmental cues and landmarks do the geese use to determine the timing and direction of their migration over the mountains? how do they find their way?
