Design an experiment by following the five principles of an experiment. As a researcher, you want
to test the effectiveness of a certain spray to lengthen the life of flowers.
Erin hypothesizes that a certain fertilizer will cause her sunflowers to grow better. She plants 12 plants chooses the first 6 that sprout to treat with the fertilizer. She measures all the plants daily, and notices that the treated plants were an average of 2 cm taller at 6 weeks. She concludes that the fertilizer causes the plants to grow faster. Which fact would lead you to question Erin’s conclusion?
The first plant to sprout was treated with the fertilizer.
Erin treated the first 6 plants that sprouted.
The treated plants were an average of 2 cm taller at 6 weeks.
Erin’s friends also conducted the same experiment.

In Florida, many plants live their lives without ever touching the ground These
plants grow on the tall trees of the mangrove forests. The seeds of the plants
never touch the soil on the ground far below. The seed breaks open and rodts
grow to support the plant as it grows. Stems begin to dimb upwards. Leaves
spread to gather the light at the top of the tree. The heavy rain and humid air
of Florida means that the plants can get all of the wwater they need right wihene
they grow. These plants are commonly called "air plants."
19 What important process within air plants is most likely different
compared to plants that live on the ground?
A. making food
B. growing leaves
C. reproducing
D. getting nutrients
20 "Spanish moss" is a common type of air plant that grows in Florida.
However, the common name is not correct. "Spanish moss" is not
actually moss. What structure would clearly show that "Spanish moss"
is NOT really a moss?…
