Explanation:
When plants with red flowers are crossed with plants with blue flowers, sometimes only red flowers are produced; other times either red or blue flowers are produced. Which gene is dominant?
Answer:
The colors you see in flowers come from the DNA of a plant. Genes in a plant's DNA direct cells to produce pigments of various colors. When a flower is red, for instance, it means that the cells in the petals have produced a pigment that absorbs all colors of light but red.
Explanation:
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
Using homologous structures and any other information (from notes, activities, etc),

Suppose that millions of years from now Australia moves to South America. Would Australia still have the same kinds of mammals? Explain your answer.
Answer:
Which best explains why Australia has life forms that do not exist anywhere else on Earth? Australia was separated from the other landmasses by geological forces. Scientists think that dolphins and whales may have evolved from a common ancestor.
Assuming that millions of years from now Australia moves to South America. Australia would not have the same types of mammals, because with the junction of the continents new conditions would suggest for animals to evolve.
What was the evolution of continents?Continental Drift is a theory that claims that, at one time, all the present-day continents formed just a single landmass, called Pangea. This supercontinent, thanks to the movement of the Tectonic Plates, fragmented several times until it provided the current shape of the land masses.
With this information, we can conclude that millions of years from now Australia will move to South America. Australia would not have the same types of mammals, as with the joining of the continents new conditions would suggest the evolution of animals.

Hence, if a marine biologist writes an article about saving whales and labels them as endangered species, all efforts should be geared towards saving the animals lest they go extinct and leave a vacuum in the functioning of the ecosystem. Every species have the critical roles they play in the functioning of the ecosystem and the extinction of any particular species represents a loss that might not be replaceable.
