The purport of mitosis is cell regeneration, magnification, and asexual reproduction,while the purport of meiosis is the engenderment of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are conventionally partitioned into two incipient daughter cells.
Answer: This is true because kinetic energy depends on speed. If there's no speed, then there is no kinetic energy.
The simplest level at which life may exist is a cell
From the equation q=mCΔT, set the q of copper = to q of water,
So --- mCΔT(copper)=mCΔT(water).
mass (Cu - copper) = 38g
mass (H2O - water) = 15g
C (H2O) = 4.184 J/g*C
ΔΤ (H2O) = 33-22 = 11*C
ΔΤ (Cu) = 33-80 = -47*C (the final temp is the same for both materials - thermal equilibrium)
C (Cu) = ?
So --- 38(-47)C[Cu]=15(4.184)(11)
--- C[Cu]=690.36/(-1786) = 0.3865 J/g*C, or 0.39 in 2 sig figs. (The negative goes away, because specific heats are usually positive)
Explanation:
2. 
First, we need to find the number of moles of 
at 300K and 1.5 atm using the ideal gas law:
Now use the molar ratios to find the number of moles of ethane to produce this much .
Finally, convert this amount to grams using its molar mass:
3. 
Convert 75 g Zn into moles:
Then use the molar ratios to find the amount of H2 produced.
Now use the ideal gas law 
to find the volume of H2 produced at 23°C and 4 atm:
