as high as someone who trains in order to vertically
jump.
In conclusion, athletes jump higher than nonathletes;
and no correlation was shown between the
calf length and the vertical jump height of the
participants, athletes, and non-athletes, with muscle
mass in the legs and training having a great influence.
In future studies, a more in depth look comparing
different types of athletes with the same and different
training regimens will be looked into.

Comparison of Chlorophyll Content of Leaves in a Green House and their normal
environment of a Cyclamen Plant (Cyclamen Persicum)

Chlorophyll is fundamental for photosynthesis, which obtains its energy
from the sunlight. The chlorophyll content varies between plants and the light
exposure with sun. Given that photosynthesis occurs more efficient in a green house,
it was predicted that the leaves inside a green house would contain higher
chlorophyll content than plants that are in their normal environment. A
spectrophotometer was used to determine the amount of chlorophyll content from
the leaves from greenhouse and normal environment. Five mL of 80% concentrated
acetone were mixed with leaf, two 6mm leaf chads in scintillation vials. Three mL
solution was inserted in a cuvette into the spectrophotometer for further analysis. It
was discovered that there wasn’t a significant difference (p = 0.41) in chlorophyll
content between cyclamen leaves inside the greenhouse and normal environment.
Therefore, the results rejected the hypothesis, which stated that the cyclamen leaves
