To maintain a line of pure-breeding peas, selective breeders would use a technique called artificial cross-pollination. This is a technique were breeders transfer pollen from the anthers of one pea plant (male parent) to a stigma of a flower (female parent).
This technique was developed by Gregor Mendel, the founder of the science of genetics. He was a monk who dedicated his time in research about how genes of plants are carried over through specific species. In his controlled experiment he used the pea plant because they are cheap and readily available from merchants who sold them in different classifications. He also used pea plants because they have the capacity to self-pollinate or cross-pollinate.
Answer:
Some of Carl Linnaeus classifications of organisms are incorrect because he classified them base on their appearances and actions

Carolus Linnaeus is the father of taxonomy, which is a system of naming and classifying organisms. He classifies organisms base on their appearances and actions instead of their relationships. He invented a system of classification called hierarchical system of classifications. This system include 8 taxa, dormain, kingdom, phylum, class, order, family,genus and species.
Answer:
The presence of ozone enabled organisms to develop and live on the land. Ozone played a significant role in the evolution of life on Earth, and allows life as we presently know it to exist. These atoms combined with remaining oxygen (O2) to form ozone (O3) molecules, which are very effective at absorbing UV rays which could be injurious to organism existence
