  1. Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with its nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.
  2. When one cell divides into two, both must have a copy of the genetic information. Therefore, before cell division occurs, the genes must also make duplicates of themselves so that all the important genetic information ends up in each of the new cells.
  3. Centromeres.… that hold together the two chromatids (the daughter strands of a replicated chromosome). The centromere is the point of attachment of the kinetochore, a structure to which the microtubules of the mitotic spindle become anchored.

Answer:

[Ba^2+] = 0.160 M

Explanation:

First, let's calculate the moles of each reactant with the following expression:

n = M * V

moles of K2CO3 = 0.02 x 0.200 = 0.004 moles

moles of Ba(NO3)2 = 0.03 x 0.400 = 0.012 moles

Now, let's write the equation that it's taking place. If it's neccesary, we will balance that.

Ba(NO3)2 + K2CO3 --> BaCO3 + 2KNO3

As you can see, 0.04 moles of  K2CO3 will react with only 0.004 moles of Ba(NO3) because is the limiting reactant. Therefore, you'll have a remanent of

0.012 - 0.004 = 0.008 moles of Ba(NO3)2

These moles are in total volume of 50 mL (30 + 20 = 50)

So finally, the concentration of Ba in solution will be:

[Ba] = 0.008 / 0.050 = 0.160 M

Identify the arrows that represent the process of cooling.<br> liquid<br> gas<br> solid
krok68 [10]

The arrows B, C, and E represent the process of cooling.

Solid state: In the solid state, the molecules are arranged in a regular and fixed pattern. The molecules in a solid are closely packed that is the solid particles can not move.

Liquid state: In the liquid state, the molecules are present in an irregular pattern. The molecules are closely packed but particles can move.

Gaseous state: In the gaseous state, the molecules are present in an irregular manner. The molecules of gases are not closely packed and can move freely.

Therefore, the solid changes to liquid on heating, and the liquid changes to solid after cooling.

Liquid changes to a gaseous state on heating while gases changes to liquid on cooling.

Solid changes to gas on heating and gases change to solid after cooling.

How do you identify an electrolyte
Alex787 [66]
" if a compound is an acid or a base, but NOT one of the strong acids or bases, then it MUST be a weak electrolyte. Strong electrolytes – ionic or molecular compounds that ionize completely in solution. Weak electrolytes– molecular compounds that are partially ionized in solution."
