1. I learned that a cladogram is a diagram that shows patterns of shared characteristics among species, 
2. How do molecular clocks contradict the event that occurs in the "Cambrian explosion"?
3. No question has been posted yet for Biology Honors.
4. It is important to learn about this topic to help us learn about our common ancestors and to give us an understanding of why some organisms atre better adapted to their environment than others over a certain period of time.
5. Scientists can determine how an organism is related to another by developing a cladogram.
6. I like this topic because I find it easier now to connect the dots between geologic events and biological evolution.

Thanks for starting it for me!

1. I learned how to create and understand a cladogram. As well as how
to create a dichotomous key.
2. Why wasn't the 5 kingdom system effective?
3. According to the article, "The Cambrian Explosion: How do we use
the evidence," molecular clocks contradict the event that occurs in
the "cambrian explosion" because "most dates for the divergence of
major phyla" occur 100 to 400 million years earlier than the
Cambrian.
4. It is important to learn about this information in order to have a
clearer understanding of how species evolve from other species.
5. This information can be used in real life to classify new species
that may have recently evolved, and their relation to other species.
6. This topic was fun and interesting to learn.

1.) I learned that yeast is the only uni-cellular fungi
2.) What is phylogenetcis?
3.) One reason is that many protists had animal, plants, or fungi characteristics.
4.) It is important to learn taxonomy to be able to learn about the classification of animals
5.) It can be used to classify new species.
6.) I enjoyed the videos.

I learned that it was linnaeus who invented the binomial nomenclature.
What is a phylum?
Phylogenetics is the study of evolutionary relation among groups of organisms.
This is applied to real life if were to want to become taxonomists, we would know the basics.
I did like this topic! I like learning about organisms.

1. I learned that in a binomial nomenclature, the genus name will be first, followed by the species name.
2. What is the difference between the tree of life and the ring of life?
3. Phylum is a taxon above a kingdom, it is broader than a kingdom.
4. It is important to understand how the binomial nomenclature is and how it is used because it is how animals are specifically labeled. It is good to know that the binomial nomenclature will be in latin. The genus, which will always have the first letter capitalized, and the species, which will be lowercased, will all be either italisized or underlined.
5. This is applied in real life. The fact that the binomial nomenclature is used to label animals without confusion!
6. I enjoyed the topic, the videos took me an incredibly long time to watch.

1) I learned that polyphyletic group leads to the suggestion of
reconstructing a tree of life or cladogram.
2) I am unsure about analogous structures. I don't understand them
although I do understand homologous structures.
3) @Natalie Toro- A ring of life includes more of the genetic
background than a tree of life by implying the creation of eukaryotes
and showing Bacteria and Archea.
4) It is important to learn about this topic because we learn how to
connect certain species and have an understanding of how everything is
related.
5) In real life molecular clocking can be used to try and distinguish
the origins of some diseases.
6) This topic was fairly straightforward and I found out easy to
understand, one of my favorite topics aside from nucleic acids.

1. I learned that despite the fact that certain animals are in
different in-groups they can create their own in-group.
2. Why is comparing morphology still used despite the fact that is
inaccurate.
3. Analogous structures are structures that do not look the same but
do the same jobs.
4. It is important to learn about this in order be able to make ties
with animals that you may not know anything about.
5. In the end its real life application was already stated, which was
to better the organization of the environment.
6. This topic was relatively easy but my lack of self-discipline
prolonged the amount of time I spent on the topic.

I. I learned that scientists use the word "Division" instead of "Phylum" when classifying plants, plant species are further divided into "varieties" and bacteria species are subdivided into "Strains".
II. why are all the Taxa capitalized except for species?
III: morphology is still used today though it is inaccurate because it is still an easy way to tell one species of organism from another, or to compare how alike two species are. There are new species discovered every day that would need to be classified and seeing how they are similar in comparison to other species is the easiest way.
IV: It is important to know this because it shows how alike species are when compared, it also shows how many animals species may have originally been related somewhere down their ancestral family tree.
V: Scientists  use cladograms to determine how to classify a newly discovered species.
VI: This might be my  favorite of the bio topics, aside from ecology. I find it fun and straightforward. :{B
