A scientist studies the DNA of three different species. The DNA from species A is more similar to DNA from species B than DNA from species C. Which species are probably the most closely related? Explain your answer.

Answers

DNA A and B are probably the most closely related because cells get DNA from the parent cells therefor similar DNA comes from relatives.

a book with a mass of 1 kg is dropped from a height of 3 m. what is the potential energy of the book when it reaches the floor?

Answers

Well, first of all, the formula for finding potential energy is;
PE=mgh
  Where; m is the mass
               g is the gravitational force or acceleration due to gravity
                h is the height. 
   Anyway, according to the question, the mass is 1kg, the acceleration due to gravity has a constant value of 10ms² . And the height is 3m. Now you just have to use all these in the formula. So;
mgh= 1 x 10 x 3. That will be 30. And the unit of potential energy is Joule. So the answer is 30 joules. Hope i helped. Have a nice day.     

Final answer:

A book dropped from a certain height has no potential energy when it reaches the floor, since the height (a factor in the potential energy equation 'PE = mgh') becomes zero.

Explanation:

The potential energy of an object of mass (m) at height (h) is given by the formula PE = mgh, where g is the acceleration due to gravity (approximated as 9.8 m/s² on Earth). In this case, however, when a book reaches the floor after being dropped, its height is 0 meters, hence its potential energy is also 0 joules because potential energy is dependent on height.

How many atoms and ions does lithium sulfite have?

Answers

Answer:

Hence the ions per mole are:

Li^(+)= 2 ions

SO_(3)^(2-)(aq)= 1 ions

In one mole of Li2SO3 , the number of the atoms are

N_(a)=6.022* 10^(23)

Explanation:

The formula of  lithium sulfite is Li2SO3.

Li_(2)SO_(3)

It contain Li+ and SO3(2-) ions.This can be represented by :

Li_(2)SO_(3)(s)\rightarrow 2Li^(+)(aq) +SO_(3)^(2-)(aq)

Hence one mole of Li2SO3 will give 2 Li+ ions and 1 SO3 (2-) ion.

Hence the ions per mole are:

Li^(+)= 2 ions

SO_(3)^(2-)(aq)= 1 ions

Number of atoms in  lithium sulfite depends upon the mass of the Li2SO3 present .

Li2SO3 = 93.94 g/mole

This mass is equal to 1 mole of Li2SO3

Now 1 mole of any substance contain Na atoms . This is known as Avogadro Number.

N_(a)=6.022* 10^(23)

Hence , if 1 mole of Li2SO3 is present then it contains Na atoms

If other then 1 mole present then number of atoms are calculated by:

Number\ of\ Atoms=Moles* (N_(a))

Here n = number of moles

if the mass of the compound is given then first calculate the number of moles.

Moles=(mass)/(Molar\ mass)

Why is it important for DNA to be duplicated before mitosis

Answers

If it didn't, one cell would end up with the original DNA, the other wouldn't be a functional cell, because it would lack DNA. If the DNA was split between the two cells.
