A shark pup has a pointed fin. Its mother also had a pointed fin, but its father had a rounded fin. Which of these statements explains why the shark pup has a pointed fin?
a
The shark pup inherited one copy of the gene for fin shape from its mother and one copy
from its father. That gene combination instructs for proteins that connect in ways that
make its fin pointed.
b
The shark pup inherited one copy of the gene for fin shape from its mother and one copy
from its father. Those genes connect together to make its fin pointed.
с
The shark pup inherited its copies of the gene for fin shape from its mother and not from its
father. Those genes connect together to make its fin pointed.
d
The shark pup inherited its copies of the gene for fin shape from its mother and not from its
father. Just like its mother's genes, those genes instruct for proteins that connect in ways
that make its fin pointed.

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
