a cell is placed in a solution of 3% starch and 3% glucose. After several hours, glucose is detected outside of the cell, but st
Alex17521 [72]

Answer and Explanation:

The cell was placed in a hypertonic solution. Glucose is a monosaccharide while starch is a polysaccharide. The concentration on the outside is higher compared to that on the inside. The cells have cell membrane that is semi-permeable.

Movement of molecules is dependent on the concentation gradient. However, the size of molecules determine the diffusion rate. Small and light molecules diffuse faster than large and heavy molecules thus glucose diffused faster than starch.

The cell membrane being permeable suggested that it allows molecules of small sizes to pass but not large ones.

A species of fly has two alleles for the length of their legs. The allele for long
stira [4]

Answer:

According to Hardy Weinberg law (p+q)2=1 where p is fequency of one allele and q is the frequency of another allele.

According the question

 q represent the short legs and 33 of 100 organism have short legs.

   As a result the frequency of q with respect to the 100 organism is 33/100

                                                                                                                  =0.33

Therefore q=0.33

 we all know that

            (p+q)2=1

             ∴  p+q= 1

             ∴  p=1-q

               p= 1-0.33

                   p=0.67

The frequency of p is 0.67
