The sympathetic nervous system is a part of the autonomic nervous system that carries stress responses or "flight or flight" responses that involves feelings of rush. The activation of sympathetic nervous system therefore increases the heart rate. The parasympathetic nervous system is another part of the autonomic nervous system which is responsible for "rest and digest" responses that involves feelings of relaxation. The activation of the parasympathetic nervous system decreases the heart rate.
Answer:
4) Replacement of GDP by GTP on the Ga after interaction with an activated GPCR.
5) Conformational change in the Ga subunit causing a decreased affinity for the Gb g subunit.
2) Dissociation of Ga from the G protein complex.
6) Ga-subunit with its attached GTP activates an effector like adenylyl cyclase.
3) Production of a second messenger, like cAMP.
1) Activation of one or more cellular signaling proteins.
Explanation:
It is a signaling cascade initiated by G proteins. These G proteins function as molecular switches capable of activating signaling pathways in the presence of guanosine triphosphate (GTP), which is hydrolyzed in order to produce energy

Answer:</h2>
Genetic engineering
<h2>
Explanation:</h2>
Genetic engineering or recombinant DNA innovation includes the gathering of procedures used to cut up and consolidate hereditary material, particularly DNA from various natural species, and to bring the subsequent half breed DNA into a creature so as to frame new mixes of heritable hereditary material.
It is the base involved in production of hybrid species which has characteristics of different superior breeds. It has wide range of application in the field of agriculture and medicines. In agriculture, it is used to come up with crops that are resistance to pest and insect.
