Answer:
They release chemical messengers to communicate with cells they may or may not be in direct contact with.
Explanation:
Unicellular organisms such as bacteria or yeast, 'talk' to each other through the release of chemicals. In bacteria, this is known as quorum sensing which allows them to determine the surrounding bacterial population density. In yeast, one of the more popular pathways is known as the mating factor pathway, which allow the organisms to find mates. Whereas, in multicellular organisms (such as humans), this chemical release allows for cell-cell co-ordination which keeps the system functioning correctly.
The color of beef is determined by myoglobin because these cells are actually responsible for transporting oxygen-rich molecules to the the tissues of the animal. This characteristic gives it the color that it has and is very abundant in large organisms like cattles.
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>
