Explanation:
This is a DIHYBRID cross because it involves two different genes coding for distinct traits. One of the traits will be dominant while the other recessive. Hence, parents that are purebred for opposite forms of the trait means that one parent is homozygous dominant while the other is homozygous recessive. When these two parents cross, they produce F1 offsprings that all possess the dominant trait but heterozygous/hybrids.
When these hybrids are self-crossed, they produce four different combinations of gametes which when crossed using a punnet square will result in F2 offsprings with a 9:3:3:1 phenotypic ratio according to Mendel's observation.
9 represents offsprings that are dominant for both traits
The two 3's represents offsprings that are recessive for one trait and dominant for the other respectively.
1 represents offsprings that are homozygous recessive for both traits.
Hence, 1 out of 16 offsprings will be homozygous recessive for both traits.

Explanation:
At divergent plate boundaries, earthquakes tend to be weak and shallow. Transform plate boundaries, have shallow, but very powerful earthquakes. At convergent plate boundaries, where two continental plates collide, earthquakes are deep and also very powerful.
Endocrine and circulatory (C) Endocrine system consists of glands and the hormones they secrete whist the circulatory system is the blood or as I like to call the “transport system” of the body.
Since bees and butterflies both pollen are flowers, the growth (population) of flowering plants would become less common without the pollen being spread.
Angiosperms are a plant classification in which the plant beard seeds and flowers, has five flower petals, and has seeds enclosed by fruits.
