Curly hair (C) is dominant where straight hair (c) is recessive. If a person who is CC were to have children with a person who is cc, could it be possible for them to have a child with straight hair? a-yes
b-no

b. no

Explanation: It is not possible because if you draw a punnett square you see that the only phenotype you get is Cc. C (curly hair) is dominant over c (straight hair) so curly hair will always be expressed.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
