It represents the dominance.
<span>The dominance occurs when an allele (dominant) that is expressed in an organism’s phenotype, masks the effect of the recessive allele that is also present. In this case allele for brown coat color (F) is dominant to the allele for white coat color (f). When these two alleles are together (genotype is Ff) the brown color will be expressed as a phenotype.</span>
breaks down the cell wall of bacteria
Answer:
"The fossil plant Elkinsia polymorpha, a “seed fern” from the Devonian period (about 400 million years ago) is considered the earliest seed plant known to date."
The reason for this change is "Technological advances led to the discovery of single-celled organisms and increased our understanding of relationships between organisms"
<h3>Why bacteria and archaea should be classified into different kingdoms?</h3>
Archea and bacteria are both prokaryotic organisms ( organisms without defined organelles and nucleus) that share common features such as a similar morphology and similar ways to obtain food/energy. However, these organisms have important differences such as RNA type, they have a slightly different morphology and they live in different habitats.
<h3>Why did this change in classification occurred?</h3>
This change occurred due to technological advances. Indeed, the classification of organisms into 4 kingdoms occurred by the beginning of the 20th century when unicellular prokaryotic organisms had not been completely studied, and therefore it has not been determined this group included two sub-groups.
