the powers that the president shares with the senate include?

Question

a) recieving ambassadors
b) making treaties
c) granting pardons for federal offensees
d) ensuring that the laws are faithfully executed

Answer 1

That's not exactly right. No powers are "shared" as you say. There are checks & balances on most ALL powers. The President recieves ambassadors w/o senate approval. He APPOINTS ambassadors, along with most everything else, with senate approval, which goes too far by the way. Treaties are ratified by the senate, but they have no say in the language. Pardons are an executive power w/o senate approval. The "ensuring" you mention is called oversight, which covers most everything unless congress grants the executive branch the power to do those things w/o reporting back (which is common on war powers/intelligence). The Senate as a whole is more powerful than the Pesident individually, but the executive branch is overall more powerful than either the legislative & judicial branches.

Answer 2

None of these poweres are shared. There is a series of checks and balances, for example a president can sign a treaty, but it must be ratified by the Senate.
