Which of the following will most likely happen when this
anticancer drug is applied to a tumor that has a high level
of EGFR?
When epidermal growth factor (EGF)—the ligand for the
epidermal growth factor receptor (EGFR)—binds EGFR
on the cell surface, the intracellular domain of the
receptor changes shape into an "active state." The
receptor then induces a cascade of kinases in the
cytoplasm, resulting in the activation of mitogen-
activated protein kinase (MAPK). One effect of EGFR
signaling is the stimulation of cell proliferation.
Overactive EGFR is frequently found in cancer cells.
O Tumor cells with active EGFR will increase and
MAPK activity in the tumor will increase.
Tumor cells with active EGFR will decrease and
MAPK activity in the tumor will increase.
O Tumor cells with active EGFR will increase and
MAPK activity in the tumor will decrease.
O Tumor cells with active EGFR will decrease and
MAPK activity in the tumor will decrease.
One strategy for developing anticancer drugs is to target
the overactive signaling proteins found in cancer cells.
Antibodies are proteins made by immune cells that only
recognize specific biomolecules, called antigens. The
major component of an anticancer drug is an antibody
that specifically recognizes and binds EGFR.

Which statement best describes a typical difference that could be found between the "analysis" and "conclusion" sections of a lab report? a) only the "conclusion" describes errors that occurred during the experiment, and only the "analysis" section suggests further research.b) only the "analysis" section includes specific data comparisons, and only the "conclusion" section suggests further research.c) only the "analysis" section discusses whether the original hypothesis was supported, and both sections include graphs of data.d) only the "conclusion section discusses whether the original hypothesis was supported, and both sections suggest further research.(the answer is b i just took the test)
