According to the information provided in the question above, Esther's physician will need to KNOW WHETHER ESTHER IS SUFFERING FROM ANY CHRONIC DISEASE OR NOT.
<span>People who are infected with
AIDS has more tendency to acquire multiple infections because the pathogen that
causes acquired immunodeficiency
syndrome (AIDS) damages the immune system of a patient by destroying the white
blood cells that fight infection. If the CD4</span>+ T cell count below 200 cells per µL and presence of
specific diseases in association with an HIV infection are observe in an
individual, then this could be an indication of having an AIDS.
Moreover, opportunistic
infections or cancer may take advantage of a very weak immune system, an
individual can develop an influenza-like illness with signs and symptoms that
includes swollen lymph nodes, fever, rash, weight loss, diarrhea and cough.
It illustrates the cycling of matter, just like in a natural ecosystem.
Option D.
<h3><u>Explanation:</u></h3>
The natural stable ecosystem is defined as the ecosystem which has the members doing their part of job and each and every member contribute to the stability of the ecosystem by completing food chains.
Here in this bottle ecosystem the boy put the stones, rocks, water which gives proper nutrition to the growing plants and animals which are also introduced by the boy. The plants produce oxygen and consume carbon dioxide whereas the animals consume oxygen and produce carbon dioxide. Thus the cycle is maintained and stability is achieved.
Answer:
The valuable organic molecules produced by autotrophs serve as sources of food for the heterotroph and supply the necessary nutrients living organisms need to grow and survive.
Without these valuable organic molecules living organisms can not survive , grow and develop.
The organic molecules serve as sources of energy needed to fuel biological processes in the organisms.
Explanation:
Autotrophs are group of organisms that can produce their own food through the process of photosynthesis where inorganic molecules are converted to organic molecules i.e they use light energy from the sun with water and carbondioxide to produce carbohydrates and oxygen.
Heterotrophs or other living organisms depend on autotrophs for the supply of organic matter as food nutrients and sources of energy needed for cellular or biologic processes.
