Answer:
For the sympathetic nervous system:
i. the preganglionic neurotransmitter is acetylcholine, while
ii. the postganglionic neurotransmitter is norepinephrine
For the parasympathetic nervous system both pre- and postganglionic neurones use acetylcholine as their neurotransmitter.
Explanation:
Sympathetic and parasympathetic nervous system are the two components of the autonomic nervous system.
The sympathetic system arises from the the thoracolumbar (T1-L2) region of the spinal cord.
The parasympathetic nervous system originate from
i. the cranial nuclei in the brainstem (brainstem nuclei cranial nerve III, VII, IX, and X), and
ii. sacral nerves (S2-S4).
Preganglionic and postganglionic neurones link both sympathetic and parasympathetic systems to their effector organs.
At synaptic junctions in the autonomic ganglia ththe preganglionic neuron of both sympathetic and parasympathetic nervous system use cholinergic neurotransmitter (acetylcholine). The postganglionic neurotransmitters are not the same for both sympathetic and parasympathetic systems. The sympathetic uses norepinephrine (adrenergic) while the parasympathetic maintains the acetylcholine.
Answer:
The cuts are that are made by endonucleases have two outcome. Either they will be of sticky ends or blunt ends. Both of these ends come as a result of type of endonuclease that we are going to use.
There are also some extra sequence fragments that came additionally after cutting procedure. For example, the endonuclease EcoR1 cut the DNA fragments from 5' end that are sticky in nature and extra fragments of AATT hang up after cutting.
Plants are producers. The give energy to the herbivores. The gain energy from the sun.
The right answer for the question that is being asked and shown above is that: "1.increase in the biodiversity of there fields" In the fall some farmers plow the remains of corn plants into the ground. this activity contributes most directly to the 1.increase in the biodiversity of there fields
<span>the bones of fibrous joints are joined by fibrous tissue, such as the sutures in the skull or the pelvis. Fibrous joints allow no movement at all. he bones of synovial joints meet in a joint capsule, such as the knee joint where the femur and tibia meet. These joints are the most common and most moveable joints in the human body</span>
