Because decomposers release nutrients, if they were eliminated, wastes and and remains of dead organisms would pile up, and the left over organisms would never make it back to the ecosystem. Hope this helped, let me know if you need a little more assistance! :)
Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart.
Isotopes are atoms of the same element with the same number of protons and different number of neutrons.
<h3>What are isotopes?</h3>
Isotopes are any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei.
As a result of this, atoms of isotopes will have the same atomic number but a different mass number.
Examples of isotopes are
- Carbon-12 and Carbon-14
- Nitrogen-14 and Nitrogen-15
Therefore, isotopes are atoms of the same element with the same number of protons and different number of neutrons.

Psoriasis is a skin disease that manifests itself in symptoms of varying severity. It is a chronic disease that can not be cured but can be alleviated by many treatments (like chemotherapy).
Photochemotherapy: also called P-UVA. It consists of the combination of UVA (a type of UV light) radiation after the local or oral administration of a psoralen that acts as a sensitizing photo. It is used alternately in patients for whom UVB (another type of UV) has no effect, as P-UVA is more effective and longer-lasting, but is associated with basiloma (basal cell carcinoma) and melanoma.
