In corn, smooth kernels (k) are dominant to wrinkled kernels (k).a farmer crosses two corn plants that are heterozygous for kernel texture. what are the odds that the offspring will have smooth kernels?

Heterozygous means 2 different zygotes. Since Smooth kernels are dominant, Zygotes KK and Kk will be smooth and kk will be wrinkled.

If you were to set up a Punnett Square chart like:

           K     k

   K   (KK)    (Kk)

   k   (Kk)     (kk)

the ratio for smooth to winkle would be  3 : 1

Which Will be 75% Smooth  and 25% Wrinkle

multiply it by 5 in order for you to understand i cant give an exact answer.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
