Muddiest Point for the second time...

Ok....so... I wrote my Muddiest point on Thursday... but obviously it didn't go through because i can't find it! :( Now that I think of it... this has happened to me before already... weird. So I'm just going to write it again.... better late than never! Well, my muddiest point is just the characteristics of the all the invertebrate phylums!

Muddiest point

My muddiest point is figuring out what specie goes to which phylum.

Muddiest POINT!

HELLO! so my muddiest point today is all of the different phylums and their classes!

Muddies Point

Hey guys! my muddiest point today is the difference between the the 3 different groups of fish, and which one is which?

Muddiest Point

Hey yall, my muddiest point is how to define all the classes and their differences.

Thanks,
Riaz

Muddiest point

Hey guys my muddiest point is remembering the different charecteristics of the different phylums. Like i have a hard time distingquising between one phylum and the other. Anyone have a good way to remember?

Muddiest Point

My muddiest point is what animals are made of no matter what backbone, like I'm kinda confused on cartillage and stuff.

muddiest point!

Hi, Heidi here, i was wondering what the difference between the three groups of fish were. If you guys can help that would be great! Thanks!

My Muddiest Point

My muddiest point is how to distinguish the three different types of fish. Is there some mnemonic device that helps you?

MUDDIEST POINTTTT

So are some fish not invertebrates and vertebrate? I'm confused with if some fish are and aren't and which are made of cartilage???

Muddiest Point!!

#Muddypoint

i have a hard time with the fish like the different kinds of fish such as the jaw-less ones i don't know how much i need to know for the test on the 3 types of fish

MUDDIEST POINT!

hi guys, i understand mostly everything this unit, but the only thing I'm having troubles with is remembering all of the phylums!

So if anyone has a method for memorizing them I would appreciate it if you told me!

Muddy Pointeroo

Hey Guys I having some issues distinguishing the main differences between the Phylums Nematoada and Annelida PLEASE HELP ME!!!!

mudddddiestttt .

Hey it's Tessa here. I need someone to help me think of a way to remember the types of invertebrates in a manageable way, so I can learn the information and not just remember it word by word.

Muddy point

Hey it's eleni and the thing I had the hardest time with is the invertabret phylums!! Can someone please break them down for me really simply?

Mooodiest Point.

ANIMAL DIVERSITY! I didn't know this unit was going to be soooo complicated! But we all survived. :) So my muddiest point is knowing the difference between class, order, family... can you guys come up with an idea to remember the order and what they represent? Ay! No me gusta nada!

Muddiest point

Its jarod. My muddiest point of the day is what are the three different types of fish are and what makes them different. Help would be great.

MUDDIEST POINT

What i need help on is understanding is, the kingdom,phylum and class. i know everytime we have the animal of the day, Mrs. Stein goes over this but i'm still very confused. if anyone can help or tell me where i can find it in our text book, that would be Great!

MUD POINT of Unit 8: Animal Diversity

My mud point from this unit is why chordates are not always vertebrates!?
Also, what are the economic and humanistic
importance of invertebrates??




-Eunice Chang <3 <3 <3

Muddy invertabrate

My Muddiest point is why we are so closely related to echinoderms and not other invertebrates

Muddie Point

hey guys!!!! its kelly and i dont get the difference between the 3 different groups of fish

uhhh, what was that?

Hey! It's Kara S. and I am confused on what evolution of jaw, lungs, feathers, ect is all about!

Scribin' it Up! Tuesday

Hey! It's Kara S. Today we briefly went over characteristics of invertebrates, because after today Mrs.Stein is sooooo done with them! We completed quite a pleasant lab, observing the comparisons between crayfish, spiders,and grasshoppers. We have our Unit exam on Thursday I believe! That's All!

A point that's muddy...

eyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy.

Hey peeps it's Trent. My muddiest point is, uh, how many eggs do mammals produce? Because it varys! Is there an average? Help would be appreciated. Yeah thanks.

Muddiest Point!

my muddiest point is about what a taxa is. thanks!

muddy point

Hey guys it's Shane, I was wondering what taxa and taxonomy have to do with invetebrates and what we are learning. I also was wondering what they mean too and if you could help that would be coo.

Scribe

Hey its Jon witht he scribe for today. As soon as we all sat down, we got our AOD!!! "Animal of the Day". Today it ended up being a Dumbo Octopus. Very little is known about this organism accapt for that it live in extreme depths, and may grow up to be about 20 cm long!! It is part of the domain Eukarya, kingdom Animalia, and phylom Mollusca. After that we quickly got working on our 2 labs, UP 13-14, andd UP 19-27. We got to observe many different Invertebrates which was a blast! We even got to touch some cool creatures. We alos get tomorrow to work on our labs which should be really fun...next scribe is.........MARK :)

Scribe

Hey its Jarod here with todays post. When we walked in today a weird butsome what funny video was playing and we had to grab the animal of the day slip. when everyone was settled we were told that the animal of the day was a weird looking animal called a Axolotl. This is also know as the mexican walking fish because it has little feet that it uses to help it swim. Its class is amphibia. It is native to mexico and a cool fact is that it is use in scientific experiments because it can regenerate most of its body parts, a characteristic that we don't have. Once we got past the animal of the day we learned about 6 different invertebrate animal phylums. We talked about Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda and last but not least Echinodermata. I am not going to go in to detail with every thing that we talked about today. Our homework was to read 26.1 and to finish the green chart. During class today you could have actually got a lot of stuff to put on the green chart but you didn't have to. Other homework is to finish the animal profile and do your reading list. The scribe for tomorrow will be.......................Jonathan b. Good luck!

New Tables!!!!!

First day back from the long weekend, its a Monday. first thing i see when i walk into my first period bio class, BOOM! new tables. these tables allow us to ask for help from our peers sitting next to us and give me more room to put my junk on t he desk. after i got over the fact that these new table, alt though a little to short for my liking, are awesome, we learned about taxonomy. when i first heard this word the first this i thought of was animals that are stuffed so they can be kept in some room. i quickly learned that this is the exact opposite. taxonomy is the study of classifying animals we learned about the different classifications of animals and which level is which in the study of taxonomy. this carried over into the next day. we continued our notes on taxonomy and did some hands on things with this by classifying different types of aliens. we then were assigned the task of using a chart to find out what species sharks where based on their physical appearance . this was actually an interesting assignment being able to use one chart to find out their species of many different animals.o ya, last but not least we learned about some strange animals over the past two days. we learned about a slime eel that has survived based on the fact that it uses its slime to get away and the star nose mole that to only is the worlds fastest eater but the fact that is relies on is amazing nose to find food. so aside from the fact we have these new awesome tables we learned some pretty interesting stuff too.

muddiest of points

if you get down to one atom left in a half life problem do you split that into another half life or do you just get rid of it?

muddiest point

hi guys I understand everything except for analogous structures (sorry if I spelled it wrong) I just can't find what they are so if someone can tell me that would be great thanks!

Muddiest Point

So I'm kind of confused on what the isolations mean, like why do they give us evidence for evolution?

Muddiest Point

My muddiest point is relative dating. I don't understand how it allows someone to tell whether one fossil is older or younger than the other D:

EVOLUWHAT?

I still don't understand the Miller-Urey Experiment, can someone explain it to me in the simplest way possible?

I DONT GET THIS vv

Radioactive dating anyone?? helpppppppp

<3 Eleni P

no comprende. Ayuda por favor?

Hey guys! TessaN heree. So I pretty much understand everything, but I missed the day when we did lab 38 about evidence of evolution. So I just want to clarify what is the difference between homologous and analogous structures?

MUDDIEST POINT

Hey, GUYS!

Heidi HERE! My muddiest point isss..........

WHAT THE DIFFERENCE IS BETWEEN AUSTRALOPITHECUS, HOMO HABILIS, HOMO ERECTUS, & HOMO SAPIENS!!!! I JUST DONT GET IT!!!! WHY ARE THEY IMPORTANT & WHATS THE DIFFERENCE???? OH AND THE "SURVIVAL OF THE FITTEST" + THE "DESCENT W/ MODIFICATION"

I know its A LOT but if you guys can help me with at least one that would be GREAT!!!!

Comment to Jarod

When Darwin was in the Galapagos islands, he noticed there were a variety of finches that existed on each of the islands. There were many different species of finch which differed in beak shape and overall size. This is adaptive radiation and natural selection at work. Remember the "sun" that Mrs. Stein drew? The adaptive radiation picture looks like a sun, because 1 species gave rise to many species.

Brudny Punkt

Hey Guys I'm kinda confused on the exact meaning of a Half-Life.

Muddiest point...

I'm clueless on Speciation and it's factors.

muddiest point!

okay, so...i'm pretty solid on most of what we covered in this chapter...but i'm completely clueless when it comes to half-lifes, radioactive dating, and everything else that was on the M&M Lab.

Stuck In The Mud

Hey guys, it's Maggie.

I was just confused if the amount of a half life changes based on the substance that its on??

Muddiest Point

Hey everyone it's Yasmin! ; )
my muddiest's points are:

1. I still don't get how to do the half-life problems...


2. Also, i don't understand how genetic drift plays a part in Evolution

If anyone can help that will be great!!!

how does it impact evolution????

hey its jessie and im wondering how photosynthesis, aerobic respiration and sexual respiration impacted evolution.

Muddiest Point

Hey it's allie and my mudiest point is... What is Genetic Drift? and why is it so important?

Muddy to the point

Hey guys, it's razmtaz!(riaz)

my point is the what exactly is the genetic drift? and where can I find it in my textbook?

Muddiest Point

Hey its jon, and my muddiest point is the MAIN differences between Darwin and Lamarck?!

Unit 7: Evolution -Mud point!!!!!!!

The hardest part of this unit was radioactive dating.... I have troubles making graphs. Also, what does "descent with modification" mean??



-Eunice Chang

Muddiest Point

Hey its Jarod. My muddiest point is what is adaptive radiation again. I forgot please help.

El pointo de mud

heyy its catie! ok so i understand what half lives are, but im still confused about what they can tell us. Like how does it give evidence about evolution, and what does it prove (besides how many atoms there are)

Muddy Point

Hey! It's Kara S. and I still don't understand how to set up the table and calculate half lives!

Muddie Point

hey guyss! its kelly and the thing that I dont get from this unit is speciation

bones in the mud

My muddiest point how does the half lives of radioactive help us understand evolution

Point in the mud

Hey guys it's Shane, there is only one thing that I'm not sure about. I'm not sure about what natural selection has to do with survival of the fittest and if you could tell me that would help.

Scribe Post =)

Today was a typical day in a BIO. Fun as always! Got to love 8th period Bio. =)

We reviewed what a half life was and how it plays a part in EVOLUTION.

We reviewed by doing an extra problem in our packet on page 29 problem B. =(

Next, we went over the quiz that we took on Friday on 19.1.

-We talked about the difference between mass extinction and background extinction. Coevoltion which is the process by which 2 species evolve in response to changes over time.Also,we learned adaptive radiation was when a small group evolved over a short time into several different forms (beaks) that live in different ways. This takes us back to how the finches evolutionized their beak to adapt to their envoirment.

3. Lastly, we finished it up with a lab! doing a lab is a very helpful way to understand evolution and the many topics that come with it!

-We measured the head and the width of the jaw to see how are brain, head and teeth evolutionized from big jaw to a round one!

Class Reflection

Today in class, we talked a lot about half lifes.

That's the time period it takes a certain type of substance to decay and decrease by half.

To help tie the lesson in with a lab we used M&Ms as an example. Starting with 100 separate pieces we put them in a cup and shook them for ten seconds, then pour them onto a plate and remove all the ones with the labeled side 'm' up. we kept doing that for ten seconds 6 times collecting the data on a chart. Then in the packet we filled out all the questions and made a line graph on our data.

of course after we were done with the lab we got to eat the M&Ms!!

**dont forget to finish up pages 31 and 32 in the packet for homework!!**

and finally...CONGRATS TO THE GIANTS :)

Scribe!

Hey it's Allie!!!!!Today in class we turned in our Lab 40 the Grasshopper leg one... which by the way was absolutely DISGUSTING!! after we took a quick quiz about our 19.2 reading, we worked in our packet, which was about time periods and eras of evolution. Finally, we were watched a video. It was really interesting on the theories about how dinosuars went to extinct.

Scribe post:

Hey its Jessie.

In class today we reviewed the blog post from yesterday (homologous structures, analogous structures, vestigial stractures, comparative embryology and molecular biology) and talked about GENETIC VARIATION, GENETIC DRIFT and SPECIATION.

GENETIC VARIATION:

-the change in frequency of allels due to natural selection

GENETIC DRIFT:

-the change in gene pools of a small population due to change(wind blew them away, fire, hurricane,ect....)

SPECIATION:

-when species develope into new species (NEEDED- reproductive isolation)

we also measured the legs of dead grasshopers, YUCK! and compleated a lab.
