Answer:
The correct answer is -
A. 2.6 × 10^9 years.
B. two half-lives.
Explanation:
According to the question, the half-life of potassium-40 is, 1.3 × 10^9 years, which means it takes 1.3 billion years to decay or disintegrate half of the initial amount of the potassium.
The half-life of K-40 = 1.3 × 10^9
The number of half-life, => (1/2)^2 = 1/4 (25% =1/4)
n = 2
number of half life = two
the time it takes = n*half lifetime
= 2 *1.3 × 10^9
=2.6 × 10^9 years.
Answer:
exponential
Explanation:
According to my research on different types of growth factors, I can say that based on the information provided within the question they initially demonstrated exponential growth. The refers to something that is growing at an alarming rate because all factors around it are in it's favor, which in this situation since there were no predators and an abundance of food the Moose had perfect conditions to thrive.

The choices for the above question are:

A. The ribosomes lining the cell membrane will make it so it can be sent out of the cell more quickly.
B.The ribosomes surrounding the Golgi apparatus will make it so it can be more easily captured and wrapped in membrane.
C.The ribosomes on the endoplasmic reticulum will make it so it can be wrapped in membrane and sent to the Golgi apparatus.
D.The ribosomes floating in the cytoplasm will make it so it can be bent into the correct shape.
</span>
The right answer is C. Ribosomes are more or less located in two general areas - freely in the cytosol or attached to the rough endoplasmic reticulum. Now, you know that these proteins will be secreted. Keep in mind then, that ribosomes associated with the ER create their proteins in the lumen or interior of the ER. The ER then packages these proteins into vesicles and secretes them to the Golgi, which secretes them to the membrane. So, ER-associated ribosomes are bound by vesicles, and free ribosomes in the cytosol create proteins are not. I hope that this is the answer that you were looking for and it has helped you.
