Ascientist hypothesized that oxygen atoms from both carbon dioxide and water are used to make glucose during photosynthesis. however, experimental results using oxygen isotopes showed that all of the oxygen from the water ended up in the oxygen molecules that were produced. none of the oxygen from water was found in glucose.

what should the scientist do to best gain scientific understanding of this topic?

a) analyze what could have happened, and change the experimental methods to retest the hypotheses in a different way.

b) discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods.

c) analyze the procedural errors that took place in the experiment, and summarize these in a conclusion statement.

d) repeat the experiment and adjust new data to support the original hypothesis.

Turtle hatchling survivorship rate is low in many turtle species due to predation. amanda researched the predatory rate on a species of turtle eggs in the red river. the eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. research suggests that predators use the female's cloaca scent to locate the eggs. the eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. the nests were monitored by cameras and manually on foot and data on nest predation were recorded. a. based on the experimental design, what is the dependent variable? b. based on the experimental design, what is the independent variable? c. based on the experimental design, what is the control?

Complete the sentences by matching the names of trees to the appropriate blanks. to do this, drag the names on the left into the appropriate blanks in the sentences on the right. match the words in the left column to the appropriate blanks in the sentences on the right. terms may be used more than once. make certain you have filled every blank with a term before clicking submit. 1. deciduous trees lose their leaves seasonally and include trees such as maple and elm. 2. conifer leaves are generally thin and needle-like, while seeds are contained in cones. conifers include cedar and pine. 3. evergreens are plants that maintain their leaves in all seasons and include trees such as cedar, elm, and pine. 4. hardwoods reproduce using flowers and have broad leaves; hardwoods include trees such as maple, , and cedar. elm returned you filled in 2 of 10 blanks incorrectly. mango trees are tropical broad leaf plants that maintain their leaves all year long. no credit lost. try again.
