The big bang theory states that the universe was formed as the result of a huge explosion.   How did the universe begin, accordi
frez [133]
In simpler terms, the Big Bang theory says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today. In the first second after the universe began, the surrounding temperature was about 10 billion degrees Fahrenheit (5.5 billion Celsius). The cosmos contained a vast array of fundamental particles such as neutrons, electrons and protons. These decayed or combined as the universe got cooler. Over time, however, the free electrons met up with nuclei and created neutral atoms. This allowed light to shine through about 380,000 years after the Big Bang.

How does cancer relate to the cell cycle??
AlekseyPX
Cancer is a mutation that occurs during the cell cycle, usually when it develops and grows it means the mutation was able to go through the cycle undetected at checkpoints so the cell was not destroyed by the lysosomes.

Would we have the Same countries If Pangea existed? And would we look the same?explain please
Natalija [7]
I don’t think we would have the same countries. i feel like everything would be connected, like maybe a few really big countries instead of hundreds of different countries. i feel we would look different that how we already look because there would be more of different type of people around each other, resulting in mixed race reproducing.

Answer:

Option B: Molecule 2

Explanation:

'Equilibrium of a molecule inside and outside a cell' means that there are similar numbers of that molecule on the inside and the outside. (hence 'equilibrium')

The number of each molecule is as follows:

Molecule 1 - Inside: 3, Outside: 5

Molecule 2 - Inside: 2, Outside: 3

Molecule 3 - Inside: 1, Outside: 5

Molecule 4 - Inside: 7, Outside: 4

Therefore the correct option is option b. 2

This is because the number of molecules inside the cell and outside the cell are the closest together, most similar out of all the molecules.

Hope this helped!
