The backbone of DNA and RNA is composed of sugar and phosphate.
DNA is double stranded due to interactions between adenine, cytosine, guanine, and thymine, which are nitrogenous bases.
Uracil is a nitrogenous base that is only used with RNA.
Is this a multiple choice question?
The correct option is this: THE MASS OF THE PROBE REMAINS THE SAME, BUT THE WEIGHT OF THE PROBE DECREASES.
The mass of an object is a measure of the amount of substance it contains and this amount always remain the same unless there is a change in quantity of matter. This is the reason why the mass of a substance will remain constant, no matter where it is placed, whether on planet earth or on another planet. The weight of a substance on the other hand is a force, whose value depends on the force of gravity. Thus, the force of gravity that exist in the place, where the object is placed will determine its weight.
Hi, the answer to this question would be an Molecular Clock. A molecular clock is a technique used by researchers that uses mutation rates in DNA to estimate the length of time that two species have been evolving independtly. Hope this helped :)
Answer:
41 cycles
If cell division went 2 cell division cycle beyond the precursor; we have 43 cycles
The volume would be = 17.59 Litres
Explanation:
From the given information:
The number of cells in the liver that developed from an embryonic precursor is roughly 
The number of cell cycles needed to produce 
cells is:
= 
= 40.86
41
Thus, nearly 41 cycles of cell division are required to form the mature liver.
Now;
Suppose 2 extra cell division cycles took place;
The total number of cells would be 2⁴³ = 1.759 × 10¹³; &
The volume would be = 1.759 × 10¹³ × 10⁻¹²
The volume would be = 17.59 Litres
