Explanation:
The cyclic universe theory is a model of cosmic evolution according to which the universe undergoes endless waves of expansion and cooling. It's any of several cosmotoligal models in which the universe follows infinate, indenfinate, self-sustaining practices.
I hope my answer helped you! Have a great day!
A rating and a Thanks would also be great!
Answer:
B
Explanation:
so you started out with 80
you have to cool it till 60
so it is decreasing which means you have to subtract
Note=if something is increasing or wanting to go up its addition but for this problem 60 is less then 80 so we are doing subtraction
80-60=20
A
Explanation:
The coiling up of DNA with the help of histone proteins - to what is called heterochromatic regions- is part of gene regulation. This makes genes inaccessible to RNA polymerase that makes mRNA from the genes. When the genes are exposed by DNA unwinding, these genes are transcribed and the resulting mRNAs are translated by ribosomes into proteins.
The DNA never unwinds completely, but rather does so region by region, because if it does so it would become so long that it wouldn't fit in the nucleus or cell.
Answer:
n C2H5OH = 0.2496 mol
Explanation:
- moles (n) = mass / molecular weight
∴ m C2H5OH = 11.5 g
∴ Mw C2H5OH = (2)(12.011) + (6)(1.00794) + 15.9994 = 46.069 g/mol
⇒ n C2H5OH = (11.5 g)/(46.069 g/mol) = 0.2496 mol C2H5OH
