Iteru [2.4K]3 years ago

Answer:

a.They evade the normal controls that trigger programmed cell death.

Explanation:

Cancer cells are cells in the body that grow abnormal and uncontrollably. Continuous growth cancer cells results in the development of tumor as well as the ability to invade neighboring tissues.

Unlike normal cells that are controlled (reproduce only when needed) and are more specialized with specific functions, cancer cells are less specialized compared to normal cells and grow abnormally and rapidly. Cancers cells grow out of control, as they evade the normal control and ignore signals that activate apoptosis or programmed cell death which is used by the body system to destroy unwanted cells.

) is every minimum bottleneck tree of g a minimum spanning tree of g? prove or give a counter example
mote1985 [20]

The answer is false. To explain further, let G have vertices {v1, v2, v3, v4}, with ends between each pair of vertices, and with the mass on the edge from vi to vj equal to I + j. Then each tree has a bottle neck edge mass of as a minimum of 5, so the tree containing of a track through vertices v3, v2, v1,v4 is a least bottleneck tree. It is not a least spanning tree, though, subsequently its total mass is greater than that of the tree with edges from v1 to every single vertex.
