Classification systems are mental models that we create to make sorting things simpler and more efficient. We make compromises to emphasize certain details and hide others based on their perceived relevance to achieving the outcomes we seek. Even if the original model was nearly perfect, you should expect the inputs provided and outcomes desired to change as time goes by.
In time, we usually find that we have over-simplified by ignoring important details. Mental models such as classification systems should evolve over time. This enables them to more accurately reflect reality and lead to the outcomes we seek.
You can only find the details you seek by observing the right layer of abstraction.
It is true that human impact on one system leads to changes in more of Earth’s systems.
Answer: Option A
<u>Explanation:</u>
Human impact had created large impacts on Earth’s systems. The pollution in air, deforestation, dumping of lakes lead to several changes in environment. Also emission of carbon, methane and other hazardous gases from several manufacturing unit effect the environment.
Along with this, increase in usage of non-renewable fuels and release of CFC's emitted from AC’s, fridge lead to elimination of ozone layer making the environment open to direct UV radiation. So yes, it is true that human impact on one system leads to changes in more of Earth’s systems.
Answer:
1) The problem is that you get a salty taste in our mouth when you drink orange juice after brushing our teeth.
Explanation:
<h3><u>Answer;</u></h3>
2, Blank, 2 ;
<h3><u>Explanation;</u></h3>
The balanced chemical equation would be;
2 CO + O2 → 2 CO2
Balancing a chemical equation ensures that the number of atoms of each element are equal on both the reactants side and the products side. This ensures that the law of conservation of mass is obeyed in chemical reactions.
Answer:
The mass of
4.6
×
10
24
atoms of silver is approximately 820 g.
Explanation:
In order to determine the mass of a given number of atoms of an element, identify the equalities between moles of the element and atoms of the element, and between moles of the element and its molar mass.
1
mole atoms Ag=6.022xx10
23
atoms Ag
Molar mass of Ag =#"107.87 g/mol"#
Multiply the given atoms of silver by
