Answer:
Osmosis is the movement of molecules from a region of lower concentration to a region of higher concentration through a semi-permeable membrane
WHILST
Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration until the molecules are evenly distributed
Joint hypermobility syndrome (JHS) and Ehlers-Danlos syndrome, hypermobility type (EDS-HT) are the tissue disorders which can be characterized by chronic pain, joint instability complications, and minor skin changes. During these, Fatigue and headache are the very common symptoms; though they can be diagnosed using specific criteria.
JHS/EDS-HT is a rare common condition that could not be diagnosed by most clinicians and pain specialists, resulting in interventions like symptomatic and non-satisfactory treatments, because there is a lack of reasonable pathophysiologic rationale.
Pain, fatigue, and headache in JHS/EDS are usually treated with the help of certain symptoms or on the basis of doctors’ experience.
<span>Therefore, in order to the cure of such symptoms, doctors suggest pathogenic mechanisms. The major aim of the re-writing of the natural history of JHS/EDS-HT is to raise awareness among clinical geneticists and specialists treating chronic pain conditions about pain and other complications of JHS/EDS-HT.</span>
Answer:
A few of the positive particles aimed at a gold foil seemed to bounce back.
Explanation:
Some of the positive particles aimed at a gold foil seemed to bounce back which gives information to the scientists that some heavy particles present in the center of the atom which bounce back the positive particles. so from this evidence the scientists says that atom is divisible and having subatomic particles such as proton, electron and neutron. Proton and neutron is present in the center whereas electron is revolving around the nucleus of an atom.
Answer:
Neurotransmitters are released from axon terminals via exocytosis
Explanation:
Dendrite is the receiving part of the presynaptic neuron, while axon is the transmitting part of the neuron. So, after initiation, action potentials travel down axons to the terminals. Action potential travels through the membrane of the presynaptic cell causing the voltage-gated channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells (exocytosis of the vesicle's content). Neurotransmitter ACh (from the vesicles) binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.
