Answer:
The simple answer is bioaccumulation resulting from biomagnification. Carnivores consume organisms at higher trophic levels, and thus "poisons," such as heavy metals accumulate in these organisms at levels greater than those found in plants. Moreover, such chemicals typically accumulate in the fatty tissues of carnivores, such as the nervous, lymphatic, endocrine, and reproductive systems.
Entropy is the term defined as a measure of the disorder of a system. This occurs mainly when the thermal energy is not available for the mechanical things.
Answer:
Work = Path function.
Energy = State function.
Distance traveled = Path function.
Enthalpy = State function.
Heat = Path function.
Explanation:
Hello,
At first, a state function is a property whose value does not depend on the path taken to reach that specific function or value, as in this case, energy and enthalpy.
On the other hand, path functions are functions that depend on the path taken to reach that specific value, as in this case, work, distance traveled and heat since different paths will provide different values for each one of them.
Best regards.
Here we have to choose the challenge which is faced by the scientist to make a hydrogen fuel cell by using water.
The challenge that the scientists are facing a. decomposition of water requires a high energy.
For the generation of fuel cells by hydrogen the use of water (H₂O) is a challenging task as the H-O bond in water is so strong and need high activation energy.
As per the mechanism of hydrogen fuel cell generation of H₂ is compulsory. Water remains in its solution as H₂O⇔H⁺ + OH⁻. The breaking of hydroxide ion (OH⁻) to form free hydrogen need a high energy, which cannot meet easily by any energy source.
The sun is always a renewable energy source as the energy of sun is infinitive.
The decomposition of water will only produce oxygen (O₂) and hydrogen (H₂) among which H₂ will be used in the fuel cell and O₂ is not at all harmful.
The excess O₂ is always good for the environment as it is the breathing source in the living system.
