The effect nervous system has on the heart rate is
Stimulation by parasympathetic nerves causes the heart rate to slow down.
The two branches of the autonomic (involuntary) nervous system regulate heart rate. The parasympathetic nervous system and the sympathetic nervous system (SNS and PNS) (PNS). To increase heart rate, the sympathetic nervous system (SNS) produces the catecholamines epinephrine and norepinephrine. The hormone acetylcholine is released by the parasympathetic nervous system (PNS) to reduce the heart rate. Your heart rate may briefly increase due to stress, coffee, and excitement, whereas it may temporarily decrease due to meditation or deep, steady breathing. Any amount of exercise will raise your heart rate, which will stay up as long as you keep exercising.

Your answer is A) Recombinant DNA. I just took this quiz. Thanks
Hi! I'm assuming you know the four states of matter- solid, liquid, gas, and plasma.
Putting them into a crime scene, however, is tricky.
Depending on which type of crime scene it is, there will be different types of states of matter in each, or possibly multiple.
Liquid can be seen as blood if it was a murder. Solid can be seen in that same crime scene if the murderer by chance left his knife, gun, or solid device they used to commit the murder. In other cases, gas can be seen used to kill someone because of it's toxicity. Plasma is a hard one, though, but can be seen in blood as well, because our blood is made up of plasma and other materials.
Hoping I helped, and I'd love to receive brainliest answer! :)
