Answer;

-A surface area/volume ratio of 6:1 means the cell's ability to get materials it needs that move across its surface is very efficient.

-Increased surface area to volume ratio makes diffusion and osmosis much more effective. Cellular concentrations of ions, nutrients, salts, etc can occur much more quickly and efficiently.

Explanation;

-The surface area to volume ratio of a cell is the relationship between two measurements.That is; the ratio of Surface area to volume. It shows the comparison between the size of the outside of a cell and the amount inside. Small or thin cells have a large surface area compared to the volume.

It depends on the unit of the ratio 6:1. If it is in <span>c<span>m<span>−1</span></span></span><span>, then it means that it is similar to a cell of size 1 cm^3,
 which is normally too big to get materials from the surface

juin [17]

Complete question:

In man, two abnormal conditions, cataracts (C) in the eyes and excessive fragility (F) in the bones, seem to depend on separate dominant genes located on different chromosomes.  Normal vision and normal bones are recessive traits.  A man with cataracts and normal bones, whose father had normal eyes, married a woman free from cataracts but with fragile bones.  Her father had normal bones.  

1. What is the genotype of the man with cataracts and normal bones?

2. What is the genotype of the woman with normal vision and fragile bones?

3. What type of offspring might this couple expect?

Answer:

  1. Cc ff
  2. cc Ff  
  3. F1)  4/16 = 1/2 = 25% CcFf, cataracts and fragile bones

              4/16 = 1/2 = 25% Ccff, cataracts and normal bones

              4/16 = 1/2 = 25% ccFf, normal eyes and fragile bones

              4/16 = 1/2 = 25% ccff normal eyes, normal bones
