Read the following scenario to answer the following question(s).Biomedical scientists have recently developed an anticancer drug delivery system that sneaks the anticancer drug into cancer cells before releasing it. They were able to do this by using two sets of liposomes. An anticancer drug (Doxorubicin (Dox)) bound to DNA molecules was added into one set of liposomes, and a high concentration of ATP molecules were added to the other set of liposomes. The drug is inactive when bound to DNA molecules. Researchers inject both types of liposomes into cancer cells, and upon doing so their contents are released. The ATP molecules from one set of liposomes bind to the DNA molecules from the other set of liposomes) and activate the drug, thus inducing cell death and decreasing tumor size.Mice with breast cancer tumors were treated with this liposome system to test the effectiveness of the drug. The scientists performed three trials–one with both types of liposomes (Dox + ATP), one with just the drug (Dox only), and one with a salt solution (control). Examine the figure below and answer the following questions.What is the best explanation for the intermediate tumor size that results from treatment with just the drug (Dox only) compared to the control and treatment with both liposomes (Dox + ATP)?

Read the following scenario to answer the following questions.An abundant and continual supply of ATP is necessary for all living cells. Toxins, reduced blood flow, and a compromised respiratory system can interfere with the transport of oxygen to active cells. A runner in a marathon faces multiple obstacles to continue to produce sufficient ATP to remain competitive.When the circulatory system cannot deliver oxygen fast enough to support a runner’s aerobic metabolism, cells switch to an emergency mode in which ________.
