It's April 14, 1912 and your journey on the unsinkable ship the Titanic is coming to an end. Luckily, you were one of the few souls to gain a seat in a life boat and as you watch the great ship tip up, then break in half and sink you are hit with a feeling of being thirsty. In the rush to get to safety no one thought to pack provisions into the lifeboat. Day after day your little party floats along in the frigid arctic air and your thirst begins to feel unquenchable. People are starting to panic and experimenting with drinking seawater to quench their thirst. You are not sure this is a good idea so you decide to solve a couple of water potential problems while waiting for rescue to determine if drinking sea water is a good idea or not. 1) The majority of dissolved ions in seawater is NaCl, roughly a 0.5 M NaCl concentration. Calculate the solute potential for seawater if you know that the water is -5°C.​

Mention true or false : a) cholera is marked by acute diarrhea and no urination. b)mosquitoes are the source of dysentery germs.

Explain two reasons you think it is important for scientists to search for new ways to treat cancer

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
