Answer:
Jet streams are very important during the weather prediction and other related aspects.
Explanation:
- Jet streams are important because they have the greatest aid in determining weather patterns all around the world.
- Meteorologists get help from jet streams to forecast weather by their position examination.
- They also carry great importance in air travel because flying in or out of them can greatly decrease the time of travel in air and fuel usage too.
- Separation of colder air from warmer air is done by the jet streams.
Answer:
A. Neurotransmitters can act as ligands.
B. Acetylcholine is a neurotransmitter. It can bind to an acetylcholine receptor on the surface of a cell. If this receptor is also a sodium channel, we would call acteylcholine a ligand and its receptor a ligand gated receptor.

Explanation:
Neurotransmitter are chemicals that transfer signals between neurons and nerve cells. They control some physical and physiologocal activity such as appetite, food.
Acetycoline is an example of neurotransmitter and it is located in the parasympathetic nervous system. Ligand are substance that form complexes with biomolecule. They serve biological purpose with this biomolecule.
This ligand binds to target site. Neurotransmitter act as ligand by binding to receptor in the postsynaptic neuron and acetycoline a type of neurotransmitter can also serve as ligand they bind to acetycoline receptor on cell surface.
