Baby chicks are pecking at grains of cracked corn of different colors. A researcher is attempting to determine if they prefer one color over
another. He counts the number of grains chosen in an arena that has
equal numbers of red, blue, green and yellow corn chunks. The
expected number here is 235. Here are his results:
red: 250 blue: 220
green: 230
yellow: 240
Perform a Chi Square analysis on these results. Don't forget to find the
degrees of freedom. Make sure to show your work to get full credit.

Suppose you have monohybrid pea plants in your garden and find that they produce round seed to wrinkled seeds in the ratio of 3: 1. if the allele are designated (r & r) receptively. what is the probable genotypes of the round seeds which produced f 1 ? rr & rr rr only rr & rr rr only rr only

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.

What are two ways that harvesting algae from the ocean may benefit human society? how might the harvest of algae negatively impact the ocean communities where that algae grows? how could this be prevented?
