the autonomic (involuntary) nervous system controls the rate at which the heartbeats. sympathetic (fight or flight) signals speed up the heart’s rate while parasympathetic (rest and digest) signals slow it down. 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.
The sympathetic nerves are responsible for activating flight or fight mode while parasympathetic nerves are responsible for restoring the normal body state.

Answer:
the type of molecule-destroying enzyme he used
Explanation:
Frederick Griffith and Oswald Avery were scientific researchers who discovered DNA. Frederick Griffith began the research and Oswald Avery continued his research in 1944 when they made the discovery of DNA. When Avery repeated Griffith's research the experimental variable in Avery's experiment was the type of molecule-destroying enzyme he used.
Answer:
<h2>1. toward</h2><h2>2. DNA ligase</h2>
Explanation:
- DNA replication is a process in which the synthesis of the new strand takes place from parental DNA or strand.
- DNA polymerase is an important enzyme that is responsible for the adding of the nucleotide and thus forms a new strand.
- During the process of synthesis one strand is synthesized in continuous forms that goes toward the replication fork and called as a leading strand that moves in 3' to 5' direction.
- The other strand that is synthesized in pieces form that is known as lagging strand and the pieces of the DNA is joined by an important enzyme known as DNA ligase.
