In humans, hemophilia is caused by a recessive allele on the x chromosome. therefore, if a female with hemophilia has children with a normal male, the probability that their first child will be a girl with hemophilia is zero. this assumes normal dosage compensation where the x that is inactivated in females varies randomly from cell to cell. but suppose the normal mechanism of dosage compensation is altered so that the x that is inactivated in any given female is random but the same x is inactivated in every cell of her body. in this case, what is the probability that their first child would be a girl with hemophilia? ( express the probability as a percent. enter the number only without the percent sign. for example, enter 100% as 100 and enter 12.5% as 12.5 )

air, water, heat and noise pollution can all be caused by producing and using technology. consuming resources - non-renewable resources, including precious metals like gold, are used to make technology

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).

explanation:

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
