A person riding a bicycle wants to move the bicycle forward. She moves her legs up and down on the bicycle's pedals. Then the rider wants to stop the bicycle. She stops pedaling and the bicycle slows. She takes one of her feet off a pedal and puts her foot on the ground to stop the bicycle and stay upright. Which of these best identifies a pathway of systems in the rider's body, as described in this scenario?
*Hint- the answers are combining the muscular system and skeletal system into the "musculoskeletal system".

A. nervous system → musculoskeletal system – circulatory system - nervous system

B. nervous system - musculoskeletal system — nervous system musculoskeletal system

C. musculoskeletal system - nervous system - circulatory system – musculoskeletal system

D. musculoskeletal system – circulatory system – musculoskeletal system - nervous system C​

Nasa scientists must work together to make sure that everything is correct and accounted for when launching a shuttle. besides a physicist, what other type of scientist would be in making sure that the shuttle has the appropriate type and amount of fuel to reach its destination?

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?
