TITLE
PHYTOCHEMICAL AND NEUROPHYSIOLOGICAL INVESTIGATION OF
PASSIFLORA FOETIDA L. (STINKING PASSION FLOWER) FLOWER
EXTRACT USING IN VIVO ASSAY.
STATEMENT OF THE PROBLEM
How many secondary metabolites will be produce after the application of
the P. foetida flower extracts?

TITLE
PHYTOREMEDIATION POTENTIAL OF Solanum melongena L.
(EGGPLANT) ON MAGNESIUM AND ZINC CONTAMINATED SOIL
STATEMENT OF THE PROBLEM

CONCLUSION
The concentration of zinc and magnesium in the soil is not correlated to
the height of the eggplant. The test of correlation shows that the value of R is -
0.1944 which shows that there is no correlation or negative correlation among the
two variables.

TITLE
ANTIBACTERIAL PROPERTY OF SEAWEED EXTRACT (Caulerpa,
Eucheuma and Sargassum) AGAINST THE FOUR IMPORTANT
FOODBORNEPATHOGENS (Pathogenic Escherichia coli, Campylobater jejuni,
Salmonella enteritiditis & Staphylococcus aureus.
STATEMENT OF THE PROBLEM
To what extent did the seaweed extracts help reduce the inhibitory zone of
food-borne pathogens?
HYPOTHESIS
This study seeks for a positive result in which the seaweed extract from
the Caulerpa, Eucheuma and Sargassum species may have the adequate power to
more or less have an antibacterial property against the said pathogens.

CONCLUSION
According to the test of correlation between the effects of the Glutathione
level in the concentration of the lead toxicity in the liver of the albino rats show a
high correlation of 0.9956. This value of R shows that there is a positive
correlation between the two variables. Thus, changing the level of Glutathione in
inducing in the liver of the albino rats will lower the lead toxicity of it.
