Answer:
Awareness was selected because it was beneficial to organisms in particular environments.
Explanation:
Based on the article, natural selection is a phenomenon that recognizes and allows traits that are useful to an organism and that would be favorable for it to be passed from one generation to another.
Natural selection marked awareness as a useful trait that would be beneficial for organisms because it helped them adapt well to the particular environments that they found themselves. For example, this ability helped an organism to be able to recognize where it could get food and light in its environment.
The heat transferred is -30J
When the gas undergoes compression, work is done on the gas and its internal energy increases.
According to the first law of thermodynamics, the increase in internal energyΔU is the sum of the heat given to the gas ΔQ and the amount of work done on the gas ΔW
The work done on the gas is 150 J due to compression and the internal energy of the gas increases by 120 J.
Therefore, the heat given to the gas is given by,
Thus, an amount of heat equal to 30 J flows out of the system.
The horizontal is s or displacement
The vertical is t or time
If a = 23 and b = 45
a + b = ?
23 + 45 = 68
