The theory of evolution is that organisms evolve over time.
Hi Kayla
Examples are ;
1) Gymnosperms
2) Angiosperms
Hint; Gymnosperms create cones to house their seeds
Angiosperms; Create their seeds inside fruits
I hope that's help:0

D)
a molecule.
Answer:
0.8684 atm
Explanation:
Using combined gas equation,
PV / T = k
P1*V1 / T1 = P2*V2 / T2
P1 = 1.10 atm
P2 = ?
V1 = 2.5L
V2 = 3.9L
T1 = 298k
T2 = 367k
P1*V1 / T1 = P2*V2 / T2
Making P2 the subject of formula;
P2 = P1*V1*T2 / V2*T1
P2 = 1.1*2.5*367 / 3.9*298
P2 = 1009.25 / 1162.2
P2 = 0.8684 atm
Here you go
This problem can be solved using one of the different gas laws, which is shown below:
PV/T
Given:
P1 = 1.1 atm
V1 = 2.5 L
T1 = 298 K
P2 = ?
V2 = 3.9 L
T2 = 367 K
Substituting the given:
P1V1/T1 = P2V2/T2
(1.1 * 2.5)/298 = (P2 * 3.9)/367
P2 = 0.868 atm
