When an organic compost pile is built correctly (sufficiently large, slightly moist, and containing a variety of organic material), it tends to get hot. which of the following best explains why a compost pile gets hot? a. solar energy hitting the pile causes photosynthetic microorganisms in the pile to begin working and releasing the stored energy as heat. b. water molecules within the compost pile spontaneously break down and release their energy as heat. c. the decomposers are breaking down energy-containing organic molecules for their own use and some of the energy escapes as heat. d. the decomposers are constantly moving around within the compost pile and the friction of their motion heats up the pile.

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?

It is believed that europa, one of jupiter’s moons has an ocean beneath its surface. based on how earth’s oceans and atmosphere are believed to have formed, what can be said about europa’s supposed ocean? the arrival of in the early days of europa’s existence could have formed its ocean. it is likely that the water experienced , similar to earth. it is also possible that this water is retained beneath europa’s surface and in its atmosphere due to europa’s .
