Cucurbits are monoecious; there are separate male and female blossoms on the same plant. The male flowers tend to open first, followed by the female flowers. It is only when both the male and female flowers are open that pollination can occur.
There is nowhere in the Constitution that says that the Congress can subpoena the President of the U.S. or his people. Congress does however have general subpoena powers, but they are not absolutely clear. There are Supreme Court cases that speak to this. They generally limit this to national security type of issues.
Presidents can ask Congress to declare war. The presidents who made such a request and had it granted were James Madison (against Great Britain â¦), James Polk (against Mexico), William McKinley(against Spain), Woodrow Wilson (against Germany and allies) and Franklin Roosevelt (against Japan and allies).
