Organize the parts of this body system in the CORRECT order according to the levels of organization in a multicellular organism, simplest to most complex..
A) human being - central nervous system - brain - nerve tissue - neurons
B) brain - neurons - nerve tissue - central nervous system - human being
C) neurons - nerve tissue - brain - central nervous system - human being
D) nerve tissue - neurons - brain - central nervous system - human being
Neurons-nerve tissue-brain-central nervous system-human being (C) is the CORRECT order according to the levels of organization in a multicellular organism (simplest to most complex).
Further Explanation:
The levels of organization are the hierarchy that is used to classify the organism according to the complexity in the organization. The cellular level is the lowest level of organization followed by tissue, organ, organ system, and organism.
The cellular level is the most simple level of organization with increasing complexity to the most complex level being the organization level. The neurons are the highly specialized cells that are responsible for the production and communication of neural signals from a part of the body to another. The axon is the tube like structure that is responsible for the passing of the impulse from one neuron to the other. A group of neurons together performing a specific function can be termed as a nerve tissue. A nerve tissue is typically found in the central as well as peripheral nervous system. The central nervous system comprises of the brain and the spinal cord. The nerves that arise from the brain are known as the cranial nerves and the ones that arise from the spinal cord are known as the spinal nerves. These systems insures the proper functioning of the body. All the information is gathered and the reflex action is initiated and processed simultaneously.
Thus, neurons-nerve tissue-brain-central nervous system-human being is the order according to the levels of organization in a multicellular organism.

a. Supply oxygen to cells for cellular respiration
b. Circulate blood through the blood vessels
c. Rid the blood of water and metabolic wastes
d. Decrease moisture stored in the blood and lungs
The respiratory system's primary job is to provide cells with oxygen so they may respire. This procedure entails absorbing oxygen from the atmosphere, delivering it to the body's cells, and exhaling carbon dioxide as waste.
The cells utilise the oxygen to produce ATP (adenosine triphosphate), which is a kind of energy. The cells then use this energy to perform a variety of tasks. The body's blood circulation is aided by the respiratory system.
It achieves this by assisting in the pumping of oxygen-rich blood to the rest of the body through the diaphragm. By doing this, it is possible to guarantee that the body's cells get enough oxygen. Finally, the respiratory system helps rid the metabolic wastes and a body of water.
Carbon dioxide, a waste product of cellular respiration, is exhaled to accomplish this. This enables the body to operate effectively by preserving thae right balance of water and metabolic wastes. In conclusion, the respiratory system's primary job is to provide cells with oxygen so they may respire.
Additionally, it aids in blood circulation throughout the body and removes water and metabolic wastes.

Answer:
Ozone is the layer (blanket) on the atmosphere that protects lives on earth, from the harmful incoming ultraviolet solar radiation. This are UV rays can damage the skins of humans. It is denoted by O₃ and is located at the stratosphere.
This ozone layer has been significantly affected due to the emission of green house gases. The use of chlorofluorocarbon (CFC), methane gas (CH₄) as well as emission of carbon and sulfur has depleted the ozone layer.
Scientists have studied and examined why this depletion is going on and have suggested many steps to avoid ozone depletion and are still trying to find out the best solution to stop this ozone depletion. The use of products that contains CFC and releases methane gas must be avoided.
The ozone depletion is observed to be maximum in Antarctica because the environment there is suitable for the events that leads top the depletion of the ozone layer.
Ozone is simply a molecule consisting of 3 oxygen atoms, which reacts strongly with other molecules. Ozone is created in the stratosphere when high energy uv radiation causes on O2 molecule to split. The free oxygen atoms collide and react with other O2 molecules to form O3.
Production is highest where the solar uv is the greatest eg near the tropics, but once created, the ozone is then circulated towards the poles by the atmosphere. The amount of ozone in the stratosphere can vary with location, season and even day to day climatic conditions.
The process of ozone creation is what makes the O3 in the atmosphere very effective at shielding the Earth from harmful uv radiation, which can cause many biological problems, such as skin cancer. However, due to its high reactivity, the uv found in the tropospher at ground level can aslo be dangerous as a toxic pollutant which is harmful to plants and lung tissue, and is a major cause of smog.
(B) It is caused by the addition of nutrients to a water system.
(C) It is most harmful when there is little flow through in the system.
(D) Phosphorus is the main causal agent.
(E) Humans are responsible for most eutrophication.
