The correct answer is E. All of the above
Explanation:
Variation in offspring can be contributed by many different events that change the DNA sequence in gametic cells. These events are crossing over, mutation, independent assortment, and random fertilization.
During the gamete formation, the different genes are assorted independently from the other gametes which results in forming various possible combinations of genes in a gamete increasing the genetic variation.
Crossing over occurs during meiosis between the homologous chromosome that results in exchange of genetic material that brings genetic variation in gametes. During random fertilization, the two gametes fuse and genetic material of two different individual comes to make an offspring which forms a genetical different offspring.
Mutation in the gametic cell is transferred to the offspring during fertilization. Therefore all contributes to variation in offspring produced by sexual reproduction.
Vascular plants, also known as tracheophytes, form a large group of plants that are defined as those land plants that have lignified tissues for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue to conduct products of photosynthesis.

Answer:
would be smaller
Explanation:
During his work, Darwin observed that the size and shape of finches' beaks varied between islands as a consequence of the food type and food availability in each island. Darwin proposed that this phenotypic variation was a response to natural selection, i.e., those organisms with more suitable beaks in their corresponding environments (i.e., islands) would be better adapted to survive and reproduce, thereby passing their genes to the next generations. In consequence, in this case, it is expected that the average size of finch beaks will be smaller because environmental factors prevent the growth of large seeds.
