What is the definition of DNA in meiosis

Chemistry
1 answer:
Eddi Din [679]3 years ago
5 0

In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells, each with half the number of chromosomes as the original parent cell. The two meiotic divisions are known as meiosis I and meiosis II.

Pavel [41]
Kc=24.4=[HX]∧2/[H2]×[X2] =(0.6)∧2/(0.2)×[H2]
[H2] = 0.36/(24.4×0.2) = 0.07377 mole

In the example, the final kinetic energy is determined to be ___________ because at the peak height, the ball instantaneously st
alina1380 [7]

TLDR: The kinetic energy is determined to be zero.

Kinetic energy is energy of motion; when an object is moving (i.e. it has speed or velocity), it has some amount of kinetic energy. The equation itself looks like so:

KE=1/2(m)(v)^2,

where "m" represents the mass of the object and "v" represents the objects speed or velocity. In this example, the ball has stopped, meaning it has no speed/velocity. This means that the final kinetic energy is determined to be zero or none, due to the lack of motion. Mathematically, you can see this by substituting "0" in for "v" (the ball is stopped):

KE=1/2(m)(v)^2

KE=1/2(m)(0)^2

KE=1/2(m)*0

KE=1/2*0

KE=0 J,

or zero kinetic energy.

Hope this helps! :)

After mixing the solutions in a separatory funnel, the stopper should be ______ and the liquid should be _______ and the layers
maw [93]

Answer:

Hence,  

1) removed  

2) drained through the stopcock  

3) get eye level with  

4) slow the draining  

5) switch to a new flask

Explanation:

After mixing the solutions in a separatory funnel, the stopper should be removed and the liquid should be drained through the stopcock, and the layers allowed to separate. When you get close to the interface between the layers, get eye level with the funnel and turn over to slow the draining heat up until the first layer is collected. Switch to a new flask get eye level with it to collect the second layer.

What is the mole fraction of HCl in a solution that contains 0.99 mole HCl and 3.6 mole H2O
marysya [2.9K]

Answer:

  0.216

Explanation:

The mole fraction of HCl is the number of moles of HCl (0.99) divided by the total number of moles in the solution.

  mole fraction = (0.99)/(0.99 +3.6) = 0.2157

The mole fraction of HCl is about 0.216.
