The best and most correct answer among the choices provided by your question is the third choice or letter C.
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection plays a role in the water cycle when "<span> gases cycle up and down based on air pressure."

Answer:
The options are
a. occur inside organelles. b. start over continually. c. are part of the carbon cycle. d. allow energy to flow in ecosystems.
The answer is b. Start over continually
Explanation:
The two cycles involves a continuous process as long as the reactants are present under suitable conditions. The cycle happens all the time due to it being necessary to produce important products all the time for the body system.
A good example involves the existing Carbon dioxide and water reacting together to get converted into substance that could provide energy (ATP and NADH) such as Glucose.
Answer:
I don't know if this will help but. The Great Sphinx has suffered from erosion and vandalism. Hatshepsut's stepson was too young to rule at the time of her husband's death, so she just took the job.
Answer:
is the density of solid calcium.
Explanation:
Formula used :

where,
= density
Z = number of atom in unit cell
M = atomic mass
= Avogadro's number
a = edge length of unit cell
We have:
r = 197 pm = 



M = 40 g/mol
Z = 4
On substituting all the given values , we will get the value of 'a'.


is the density of solid calcium.
<span>Technically, this question is badly worded. If all 4 containers were at STP, then all 4 containers would have the same pressure. So I'll assume instead that all 4 containers are at the same temperature, and then use the ideal gas law to determine the relative internal pressures of each container.
The idea gas law is
PV = nRT
where
P = Pressure
V = Volume
n = number of moles
R = Ideal gas constant
T = Absolute temperature
Since all the containers are at the same temperature, we can ignore the R and T parts of the formula and substitute some value K for constant. So we get
PV = nK
Now solve for P
PV = nK
P = nK/V
From the above, you can see that the pressure is proportional to the number of moles divided by the volume. So let's calculate that value for each container.
Container A: 0.5 / 11.2 = 0.044642857
Container B: 2 / 22.4 = 0.089285714
Container C: 1 / 22.4 = 0.044642857
Container D: 2 / 11.2 = 0.178571429
So as you can see, the pressures in containers A and C are the same, which is the first available option, so you are correct.</span>
