Answer is: yes, it is <span>possible to be </span>reinfected<span> with the norovirus.
</span>Noroviruses ( food poisoning) are cause of acute gastroenteritis - diarrhea and vomiting. People are infected with noroviruses when they eat or drink contaminated foods and liquors. <span>Once someone </span><span>caught </span>norovirus<span>, </span>they<span> are immune to the illness for around 14 weeks.</span>
Isotonic solution nothing happens to the cell it exists as it is.....in a hypotonic solution the cell will shrivel up and in hypertonic solution it will swell to the point of rupturing (aka cytolyse)
Answer: it's 3CO2+4H2O+Energy
Propane is a linear alkane of formula C3H8. It is mainly used as fuel (this is the main component of liquefied petroleum gas) in cooking and chemical industry reactions.
The reaction of its complete combustion by the presence of oxygen is:
C3H8 (gas) + 5O2 ==> 3 CO2 + 4H2O + energy (2220⋅kJ)
As we can see, propane can release carbon dioxide and water as every combustion reaction, and a lot of energy in the form of heat.
Answer:
2.Less than 73% of the populations would have only one allele present.
Explanation:
The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.
Using a larger breeding population would not be expected to alter the outcome of the experiment.
Answer:
Phenotype genotype Number of individuals
Red RR 245
Pink Rr 210
White rr 45
Number of alleles in total
R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency
r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency
Predict (Hardy Weinberg) genotype frequencies=
p^2 + 2pq + q^2 = 1
p= 0.7
q=0.3
0.49 + 0.42 + 0.9 =1
According Punnett Squares in F1 we have=
Rr* rr = Rr 50% and rr 50%
