Answer:

Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm

<em>Note: The question is incomplete. The attachment below gives the complete question</em>

Explanation:

The outermost surface of a cell is bounded by the plasma membrane which functions to maintain the integrity of the cell as well as control the movement of particles in and out of the cell.

The ratio of the surface area of a cell to the volume of the cell indicates how big the cell is. When the surface area to volume ratio is small, the cell is very big, but if the surface area to volume ratio is big, the cell is small.

From the attachment below, the surface area (plasma membrane) per volume of plasma of the rectangular solids are as follows:

Solid 1: 10/2 = 5 cm⁻¹

Solid 2: 12.18/2 = 6.09 cm⁻¹

Solid 3: 19.0/2 = 9.5 cm⁻¹

Solid 4: 34.24/2 = 17.12 cm⁻¹

Solid 5: 65.79/2 = 32.895 cm⁻¹

Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm

Two autosomal genes, J and K, are 60 map units apart. You perform the following testcross: J K / j k x j k / j k. At what freque
Dmitry [639]

Answer:

  • J K / j k = 20%
  • j k / j k = 20%
  • J k / j k = 30%
  • j K / j k = 30%                

Explanation:

To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.

The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.

So, en the exposed example:

  • J and K are autosomal genes
  • J and K are separated by 60 M.U.
  • 60 M.U. means that there is 60% of recombination.

Cross)             J K / j k                    x                  j k / j k

Gametes) JK  Parental                                     jk, jk, jk, jk

                jk   Parental                                  

                Jk   Recombinant                          

                 jK   Recombinant

One map unit equals 1% of recombination frequency. This means that every 100 meiotic products, one of them is a recombinant one.

1 M.U. -------------- 1% recombination

60 M.U. ------------ 60% recombination

                              30% Jk  +  30% jK

100 M.U. - 60 M.U. = 40 M.U.

40M.U.--------------40 % Parental (Not recombinant)

                            20% JK   +   20% jk

Punnet Square)           JK       jk      Jk      jK

                          jk     JK/jk   jk/jk   Jk/jk   jK/jk

J K / j k = 20%

j k / j k = 20%

J k / j k = 30%

j K / j k = 30%
