Answer:
through natural selection
Explanation:
Natural selection is the driving mechanism of the evolution of species. Organisms can survive more in an environment if they are capable to adapt the changing environmental conditions. After surviving they are also able to pass their modified trait into their future generations (evolution).
Helpful variations accumulate through natural selection, as the organisms that are better adapted to their environment reproduce offspring with the same variations.
It's quite simple...
You have to show a plant and draw and arrow coming towards the leaf to represent the intake of carbon dioxide and an arrow drawn from the leaf into the surroundings to represent the oxygen being released after the photosynthesis. You can also draw a sun at one corner and show the sun rays reaching the plant as well as the water being taken in by the plant through the roots from the soil.
Hope it helps!!!
For conversion of kPa and atm, the relationship is 1 atm = 101.325 kPa. So for 20000 kPa, the atm number is 20000/101.325=197.4 atm.
Answer:
Final pressure of gas = 2 atm
Explanation:
Given data:
Initial pressure of gas = 1.50 atm
Initial temperature = 27°C
Final temperature = 127°C
Final pressure of gas = ?
Solution:
Initial temperature = 27°C (27+273 = 300 K)
Final temperature = 127°C ( 127+273 = 400 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1.50 atm / 300 K = P₂/400 K
P₂ = 1.50 atm × 400 K / 300 K
P₂ = 600 atm. K /300 K
P₂ = 2 atm
