I think it is the cell membrane, but there is a possibility it is the cell wall. I think the cell membrane is correct because the skin does allow certain things into your skin cells, such as water. Similarly, cell membranes allow certain things in the cell. The cell membrane basically acts as the security guard of the cell.
Answer:
The rock is 3.75 billion years ago.
Explanation:
Given that:
Half life = 1.25 billion years
1 billion years = 10⁹ years
So,
Half life = 1.25 × 10⁹ years
Where, k is rate constant
So,
The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹
Initial amount [A₀] = 80 micrograms
Final amount ![[A_t]](https://tex.z-dn.net/?f=%5BA_t%5D)
= 10 micrograms
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
So,
So,
<u>The rock is 3.75 billion years ago.</u>
Kevin is more likely to, because he is learning slowly about what he just learned thus making the studying easier and he will learn more throughout the year.
The answer is B: Since most southern states would rather agree with the DOE instead of the Constitution, they are going to stand by to honor the details written in the DOE.
