Answer:
subluxation.
Explanation:
Subluxation is the partial displacement of a bone from its joint.
Dislocation is complete displacement of a bone from its joint.
Luxation is complete separation of joints.
Sublocation generally return to its normal position without the help from orthopedic doctor.
Example; Nursemaid's elbow caused by subluxation of head of radius from annular ligament.
The independent variable is a variable that can be stood alone. So therefore, the independent variable would be how long it takes to parachute.
Electron shell is the outer orbital, while the inner orbital are just called orbitals.
Answer:
b) opening calcium pores in the membrane
Explanation:
The opening of calcium ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons to the tip of the post-synaptic membrane. at the <u>neuromuscular junction </u>These neurotransmitters can either be <u>cholinergic or non-chorlinergic.</u> <u>At the tip of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.</u>
The neurotransmitters, diffuse through the neuromuscular junction to bind with the receptors on the <u>post-synaptic membrane on the post-synaptic neuron.</u> This stimulates opening of<u> ligand gated sodium ions,</u> and sodium ions diffuse into the post-synaptic neuronal membrane, to cause <u>depolarization</u>. if the stimulus is up to the threshold levels it generate action potential.
Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP generation.
The earliest forms would be plants and other life like that, and current day would be mostly humans and animals and a lot of plants are disappearing
