Olegator [25]

Answer:

a) Teeth arose from the rough scales of ancestral sharks.

b) Skeletal developments leading to the amphibian movement onto land probably evolved from lobe-finned fishes.

d) The anterior gill arch formed the basis for the evolution of the vertebrate jaw.

Explanation:

The animals we know today have physical characteristics that are evolutionary adaptations of characteristics of their ancestors, which have undergone a series of evolutions and modifications over the years giving rise to new species that have resulted in the species we know today. This process of evolutions and adaptations also happened with the ancestral species of fish, which allowed that today, they had characteristics such as teeth and jaws. Many of these evolutions occurred even in different species, such as the evolution that allowed the amphibians to have a skeleton, which evolved from the spine fins of fish.

In corn, smooth kernels (K) are dominant to wrinkled kernels (k).
Roman55 [17]

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
