In order to calculate the distance between two alleles/genes that are found in the same chromosome, we need to know how often crossing-over happened (recombination frequency). We know from the text that white eyes were linked to miniature wings and that wild type eyes were linked to wild type wings, so any phenotype that's contrary to these parent combinations are a result of crossing-over. We know then that 230 flies + 240 flies were a result of such recombination. To calculate the recombination frequency we only need to divide these flies (total of recombinant flies) by the total of flies in the offspring and turn it into percentage.
=0.47
0.47*100%=47%
47 map units is the distance between the genes <span>for eye color and wing length.</span>
Answer:
The correct option is A. Matter is conserved during the burning of wood
Explanation:
One of the major theories of matter states that the amount of mass at the start of a reaction is equal to the amount of the mass at the end of the reaction.
As in Joan's study, he shows that the amount of carbon atoms remain 840 during each of the combustion reactions. The number of carbon atoms in wood at the start of the reaction was equal to the number of carbon atoms in carbon dioxide at the end of the reaction. Hence, Joan's model supports the theory that matter is conserved during the burning of the wood.
Answer:
Pneumonia may be defined as the medical condition in which the inflammation might occur in the lungs due to which the fluid might accumulate in the lungs. The infection might occur by the Streptococcus penumoniae bacteria.
The most likely diagnosis of this patient can be influenza. The symptoms shown by the patient like cough, fever, headache, lung pain is more common in influenza. The diagnosis can be based on the symptoms shown by the patient and no presence of the Streptococcal infection. This conditions can be worsened if the pneumonia follow the harsh influenza and this secondary infection must be monitored. The treatment that can be preferred in this patient bed rest, anti pyretic medicines and proper body fluids.
In order to interpret the results obtained from this kind of survey, we simply could not rely on the number alone.
So, the data analysis that he would likely to apply to interpret the results would be : Qualitative and inferential
hope this helps
