question 6

Multiple Choice

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 (type A) ,and a high concentration of ATP molecules were added to the other set of liposomes (type B) .The drug is inactive when bound to DNA molecules.Researchers inject both types of liposomes (A and B) into cancer cells,and upon doing so their contents are released.The ATP molecules (from liposome type A) bind to the DNA molecules (from liposome type B) 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 statement regarding this data is TRUE?

• A)The weight of the tumors will not change if not treated with Dox or Dox + ATP.
• B)Tumor weight decreases when you add Dox only to cancer cells.
• C)Adding Dox only or Dox + ATP result in similar decreases in tumor weight.
• D)Dox is entering the cancer cells via endocytosis to induce cell death.

Definitions:

Superordinate Words

are general terms that encompass a broad category of items or concepts, opposite to more specific or subordinate terms.

Subordinate Words

Words that convey a lesser rank or importance and are typically used to combine with other words to form subordinate clauses.

Predisposed

Inclined or susceptible to a particular condition or outcome, often due to genetic or environmental factors.

Sensitive Period

An early period during the development of an organism when it is particularly responsive to environmental stimulation. Outside of this period, the same environmental events have less impact.
