Beta-blockers decrease heart rate and blood pressure. Answer:D
It is a drug that might be used specifically to reduce heart rate in cardiac patients. The drug is also referred to as beta-adrenoceptor blocking agents and are prescription-only medicines (POMS).
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.
I believe the answer would be D) kitchen scraps and grass clippings
