There is actually no membrane bounded or enclosed organelle that contain the genetic content and or information within a prokaryote. In bacteria, for instance the bacterial genome, which is that of a enclosed single double stranded circular DNA molecule is associated with histone like proteins and found within the cytoplasmic region of a cell in an irregular manner. It is termed the nucleoid.
If by Period you mean Column, they share the same amount of electrons in their outer shell.
D) 250l
Explanation :
250,000/1000
Answer:
5.56 × 10^23 molecules
Explanation:
The number of molecules in a molecule can be calculated by multiplying the number of moles in that molecule by Avagadro's number (6.02 × 10^23)
Using mole = mass/molar mass
Molar mass of N2O4 = 14(2) + 16(4)
= 28 + 64
= 92g/mol
mole = 85.0/92
= 0.9239
= 0.924mol
number of molecules of N2O4 (nA) = 0.924 × 6.02 × 10^23
= 5.56 × 10^23 molecules
When sunlight hits the moon's surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C).
