Answer:
If there is low genetic diversity, she needs to introduce something into the system to increase the variation. I would suggest breeding the orange trees with other new orange trees to change the allele frequencies, which is called gene flow.
Likely the fungi are attacking them somewhere that they have decreased resistance, and if more alleles were introduced, there would probably be evolution towards a genotype that promotes defense against these fungi.
Simple squamous epithelium
Answer:
XY/PQ=YZ/QR=XZ/PR
35/28=YZ/12=30/n
35/28=30/n
5/4=30/n
5n=120
n=120/5
n=24
The organism should be re-incubating to permit it to have additional opportunity to create finished results that might be acidic. It may be the case that there isn't sufficient finished result to change the shade of the Methyl Red yet.Some microbiologists prescribe re-brooding life forms delivering methyl red-negative outcomes for an extra 2 to 3 days to build test sensitivity.
