The part or parts of the heart that forms sympathetic and parasympathetic neurons form synapses is called cardiac plexus.
Cardiac plexus is a plexus of the nerves that are present at the base of the heart and is divided into superficial and deep part. The sympathetic and the parasympathetic nerves form synapses with heart in the form of cardiac plexus.

Answer:
The correct answer is peas have characteristics that have two forms.
Gregor Mendel used pea plant <em>Pisum sativum </em>as a model plant for his experiments. There are many applications behind his choice, one of which is observable characteristics with contrasting traits.
Pea plant has many observable characteristics which exist in two forms for example:
- Plant size (tall or dwarf)
- Pea color (green or yellow)
- Pod shape (yellow or green)
- Flower color (purple or white)
- Pea shape (round or wrinkled)
Other benefits were like: short life cycle, it produces a good number of offspring in a cross, easy to breed or cross-pollinate, hybrids were liable, bisexual flowers which makes it easy to produce true-breeding etc.
