I think the correct answer from the choices listed above is the third option. The DNA is used as a molecular clock in the sense that the <span>percent of carbon in DNA is compared between parent and offspring. Hope this answers the question. Have a nice day.</span>
Answer:
Cells from the cheek are a type of epithelial cell, similar to skin. ... They can be seen faintly even at 40x (scanning power), but the most dramatic images are at 400x where the nucleus is clearly visible as a dark spot in the center of the cell.
Explanation:
I believe the answer is predator but I could be wrong
The 50 pound object will reach the ground first.
Explanation:
Using the second equation of motion, we can derive the time taken for each of the object to reach the ground. As the object is thrown from the top of the bridge or cliff, acceleration due to gravity will be acting on them.
So, 
The value of s for the object thrown from 50 foot bridge is given as 50 ft. The initial velocity of the object will be zero. The acceleration can be written as the ratio of mass to gravitational force.
Then, 


Then, consider the time taken for the 50 pound object to reach the bottom of 100 ft cliff as t₁ and the displacement in this case is 100 ft.
Then, 

Since, the gravitational force acting on both the objects will be same, the ratio of time taken is

So, the time taken for the 20 pound object to reach the ground of 50 ft bridge is √5 s =2.236 s and the time taken for the 50 pound object to reach the ground of 100 ft cliff is 2 s.
Thus, the 50 pound object will reach the ground first.
These countries, together with the United States of America measure output through the calculation of complex indexes and metrices which, when taken together, are known as the Gross Domestic Product (GDP).
Both the economic peaks and cycles refer to other things, which are mildly related to the gross domestic product.
