Researchers are studying the abnormal activity of kinases in relation to cancer. Theoretically, how might researchers use signal transduction pathways to influence the environment of cancer cells for treatment? a Disrupt the function of protein kinases involved in cell cycle regulation
b Inactivate epinephrine receptors on cancer cells
c Stimulate the production of cAMP in cancer cells
d Alter G protein-coupled receptors involved in cell cycle regulation to be active in the absence of their normal signaling molecules

1. the passing of is the basis of heredity. 2. our encode the instructions that define our traits. 3. each of us has thousands of genes, which are made of and reside in our chromosomes. 4. in addition to our genes, the we live in also define our traits. 5. humans have two complete sets of chromosomes. 6. when parents conceive a child, each parent contributes set of chromosomes. 7. every child receives of its chromosomes from the mother and half from the father. 8. this transfer takes place at when the father’s sperm joins the mother’s egg. 9. while most cells in our bodies have two sets of chromosomes, or a total of egg and sperm each have chromosomes. 10. when egg and sperm unite they create a single cell called a 11. each parent contributes complete set of chromosomes to their child. 12. since the parents contribute the chromosomes to each new child, every child inherits a unique set of chromosomes. 13. as a result, every baby will have a combination of traits.

19. scientists use meteorites that hit earth to provide evidence of the composition of earth's interior because they hypothesize that

Legumes, a type of plant, require rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen during photosynthesis. rhizobia use the legumes for food. what would most likely happen to the legume population if rhizobia suddenly became extinct?
