muddiest point

Hi! (i was absent so i didn't know the muddiest point was due, sorry!) Anyway, i am having trouble with the difference between Phylum and Class. thanks

Muddiest Point

Hi guys I'm still confused on the differences between reptiles and amphibians. I just can't identify the differences. If someone could help that would be great.

Muddiest Point!

Hey, sorry but this is going to be a long one so I understand if you don't answer all of my questions.
Questions:
  1. Explain how the taxonomic system shows evolutionary relationships and discuss the importance of biochemistry in taxonomy.
  2. Discuss the ecological, economic, and humanistic importance of invertebrates.
  3. Describe the roles arthropods play in social behavior, predator/prey relationships, and symbiotic relationships.
I hope you can help!

Hey guys, I am having trouble telling the difference between amphibians and reptiles and platyhelminthes and nematoda. If someone could help me that would be great!

Muddiest Point

Hey guys! I am having trouble with the difference between Platyhelminthes and nematoda. If someone can help that would be great!

Muddiest Points!

Hey guys!

I need help memorizing the classifications (family, class, etc.)!
Please tell me a good way to memorize them.
Also, I'm a little confused about the domain.
Can someone explain to me what it is and the examples of it?

Thanks guys!

Muddiest Point

Hey guys! I'm a little confused on the difference between the two Phylum's Nematoda and Playthelminthes. If someone could explain to me how to find the difference between them, it'd be great. thanks!

muddiest points

I'm a little confused on how you can figure out we classify the different kinds of worms..
thats a little hard to understand.

please help! thanks!

Muddiest Point

The confusion i have is with the fancy names, and knowing where they belong like chordata i know is under Phylum but other ones not so sure. Also when you look at an organism and tell which kingdom, phylum it goes to. Help is needed. Thanks you.

Muddiest Point

I was looking at the objectives and i didn't really understand what the ecological, economic, and humanistic importance of invertebrates and vertebrates means. Also, in class today, I didn't understand what the body cavity was.
Thanks.

Hey everyone!
So my muddiest point is probably what it means to have radial and bilateral symmetry. I just don't understand the true meanings of them.

Thanks!!

Muddiest Point

Hi guys,
I am having trouble understanding the ecological, economical, and humanistic importance of invertebrates. If someone could please explain this to me that would be awesome.
Thanks!

Muddiest Point!

Hello everyone,
What I am so confused is how I can tell the difference between Platyhelminthes and Nematoda. I cant seem to find a significant difference that will help me tell the two apart (besides their physical appearance).  Thanks!

Muddiest Point

What is aceolomate, and coelomate? What does it have to do with invertebrates and vertebrates?
Also, is the studying of classification taxonomy? That word confuses me..
Thanks!

Muddiest Point

Hi guys,
I am confused on the radial symmetry. Why does a starfish have radial symmetry and not bilateral?

Hello Everyone,

I am having trouble understanding the ecological, economic, and humanistic importance of
invertebrates and vertebrates.

Thanks,

Muddiest Point!

Hey guys. Can someone please explain to me what exactly is the difference between Platyhelminthes, Nematoda, and Annelidas? Thanks!

Muddiest Point!!!

Hey everyone the one thing I'm confused about is the phylum. I'm really just wondering what it is.
If someone could help that'd be great!

Thank you!

Scribe 2/17

Hi ya'll

So all we really did on Friday was continue working on the General Classification of Invertebrates Lab and the Investigating Invertebrates Lab that we started on Thursday. We had to classify different invertebrates as well as answer questions in our packets about the different stations we visited.

Homework:
Finish UP 13-14, and 19-27
Invertebrate Profile (UP 3-4)

STACIE will be the next scribe

Scribe 2/16

Hey y'all!!

Today we started class of with our Animal of the Day!
Today the animal was the Dumbo Squid. It's called that because it has huge ears just like Dumbo the elephant from the Disney movies. The huge ears help it swim around in the sea.

After we finished talking about the Dumbo Squid, we started doing the General Classification of Invertebrates Lab and t
he Investigating Invertebrates Lab. We had to go from station to station and learn about different animals and do the packet pages along with them. We are going to be continuing this lab tomorrow because we didn't have enough time to finish today. Some of the different groups contain leeches, millipedes, coral, sponges, or jellyfish.
Homework:
Invertebrate chart with open chart quiz due tomorrow
Finish UP 13-14, and 19-27 for Monday
Invertebrate Profile (UP 3-4) due Monday


The Next Scribe Will Be: Rachel

Muddiest Point

I'm unsure of the theory and process of relative dating. How can people figure out how old a fossil is?

Muddiest Point

Im a bit confused on the results of the Miller and Urey experiment. I know they didnt create life, but what EXACTLY did they create?

muddiest point

Can someone help me with coevolution, convergent evolution, adaptive radiation, puncated equilabrim, and gradualism? sorry about the spelling errors. Thanks!

muddiest points

I'm still confused about the miller&uray experiment? please HELP(:

Muddiest Point!

My muddiest points would probably be about genetic drift and gradualism. I don't really understand them completely... If you could help that'd be great!!!
Thanks!!

Muddiest Point

Hey guys! I am having trouble with understanding punctuated equilibrium and convergent evolution. If anyone can help me understand them better that would be great.

Thanks!

Muddiest Point

I'm having trouble understanding what relative and absolute dating is. Also what is a genetic drift?
-Thanks!

Muddiest Point

Hi Guys,

I'm having a little trouble understanding what adaptive radiation is. If someone could explain it to me that would be great!

muddiest point!

hey, i was just wondering what the difference between relative and absolute dating is, and also what is the fossil record? Thanks!
-ChristinaP

Muddiest Point

Hey Guys. I'm having some trouble understanding what endosymbiotic theory is and how it works. I also don't really understand the Miller-Urey experiment and what it concluded. Thanks!

Muddiest Point!

Hello everyone! A couple of terms I do not know when I read over when I looked at our objectives sheet are Cenozoic, Mesozoic, Paleozoic, and Precambrian (All of those words are under #8 on the objectives sheet). I didn't quite recognize them and I need help understanding what they are.
Thanks!

Muddiest Point!!!

Hey guys! This unit has been going pretty well! The only thing I am confused on is the differences between Darwin and Lamark and what they each discovered about evolution. Thanks!

Muddiest Points!

Hi guys!
It would be great if you could tell me the main differences between Darwin and Lamark. It would also be helpful if you could tell me the differences between hominoids and hominines.
Thanks! :)

Muddiest Point!

Hello Everyone,

My muddiest point is defining convergent evolution and genetic drift.
It would be greatly appreciated if someone could explain this to me!

Thanks,

Sonya A.

Muddiest Point

Hi guys, i don't get what radioactive dating is, I am just really confused with the whole subject of it. Can someone explain it to me please? thanks(:

Muddiest Point

Hi, guys I am still confused about convergent evolution. I don't understand the difference between convergent and regular evolution. Please help, Thanks

Muddiest Point

Hey guys. I'm a little confused why Lucy, Australopithecus, is not our ancestor, but is our relative. I'm also kind of confused about how Darwin developed the theory of natural selection. If you can help me out that'll be great! Thanks!

Muddiest Point

My muddiest point is adaptation. What is it, and how does it relate to the principles of fitness and Darwin's observations? Also, what is survival of the fittest? I looked over the definition, but it just doesn't make sense.

Thanks!

Muddiest Point!!!

Hi everyone,

I'm confused on what convergent evolution is. If someone could help that'd be great!!

Thank you!

My Muddiest Point

I dont uderstand why Lamark believed that animals had a desire to change. What evidence did he collect to make him believe his hypothesis?

Scribe 2/1/12

Hey Guys! The first thing we did today was turn in our Lab 38.

Next, we took some notes on Genetic Variation. Here they are:
  • In terms of genetics, evolution is the change in frequency of alleles in a population's gene pool.
  • Natural selection leads to change in gene frequency.

Genetic Drift
  • Changes in the gene pool of a small population due to chance.
  • Occurs when a small group colonizes a new habitat- founder effect.

Speciation
  • Species- group of organisms that interbreed to produce fertile offspring under normal conditions.
  • For new species to form, reproductive isolation needs to occur, where organisms don't interbreed and gene pools separate. This can occur because of:
  • Behavioral Isolation: when populations have different courtship rituals or other behaviors.
  • Geographic Isolation: when populations are separated by geographic barriers.
  • Temporal Isolation: when two or more species reproduce at different times.

Next, we did Lab 40, from our biology lab books. We worked with our lab groups and we each got four grasshoppers and a ruler. We had to measure the femurs, or the top parts of the jumping legs. After we measure all of the femurs from the four grasshoppers, we compared all of the data from the whole class. We used this data to create a graph and see the variation in the grasshopper legs. Below is a picture of the grasshoppers we had to use to measure the femurs.



Homework:
  • Finish Lab 40
  • Read 19.2
