The false statement is: All deuterostomes exhibit radial symmetry in their bodies.
For example, phylum Chordata contains animals that don’t have radial symmetry.
Deuterostomes share characteristics such as coelom that forms from folds of archenteron, radial, indeterminate cleavage, anus formed from blastopore.
The major distinctions between these two groups of animals (Bilateria) deuterostomes and protostomes are in their embryonic development. Another difference is that most Protostomes have schizocoelous development (cells fill in the interior of the gastrula and that is the way the mesoderm is formed) On the other side, in Deuterostomes, the mesoderm forms through invagination of the endoderm (enterocoelic pouching).
No, light dependent reaction does not depend on Calvin cycle.
Calvin cycle occurs in the second phase of photosynthesis i. e. light independent reaction. In this process, carbondioxide fixation takes place in the leaves of the plant. Light dependent reaction occurs first in which ATP and NADPH are produced which are used in Calvin cycle of light independent reaction for the production of sugar molecule such as glucose. So light dependent reaction does not depend on Calvin cycle.
If the initial hypothesis is not supported, you can go back to the drawing board and hypothesize a new answer to the question and a new way to test it. If your hypothesis is supported, you might think of ways to refine your hypothesis and test those.
Failure to support hypotheses is common in science, and often serves as a starting point for new experiments. Go back to the statement of hypothesis in the Introduction. Then review your findings, the data from the experiment. Make a judgment about whether or not the hypothesis has been supported.
It is verified by testing it. If the data supports the hypothesis, then we consider the hypothesis to be verified and true. If however, the data does not support the hypothesis or refutes it, then the hypothesis is in trouble, and we have to come up with a different hypothesis to explain the observations.
Explanation: ... If the data consistently do not support the hypothesis, then CLEARLY, the hypothesis is NOT a reasonable explanation of what you are investigating. The hypothesis is rejected, and we search for a new interpretation, an new hypothesis that supports the experimental data
