Members don't see this ad.

Honestly if you know this u will probobly get a 30

1. Is coral a type of Jellyfish and if so what stage does it represent?
2. What are the functions of spogy bone and compact bone and in which one does RED blood cell are made and which one holds fat?
3. Why doesnt the pituitary have exocrine and endocrine also? what is a tropic hormone?
4. wtf is batesian and mullocrin?
5. can someone explain neurlation?
6. Hardyweinberg why is one creteria "no isoloation" and what does that mean?
7. Both bacteria and plants have cell walls, how do they differ? does a fungi have cell walls?
8 what is difference between degenerate and redundancy?

3. trophic hormones are different than direct hormones. look it up on wiki. i forgot the difference

4. those are types of mimicry
so u know how a lot of bugs are black and yellow. so this makes predators aware not to mess - think of bees, etc. this is mullerian mimicry.

batesian mimicry is when animals have this characteristic (black and yellow) but don't actually have this defense mechanism.

6. i dont know if thats true. hardy-weinberg requirements:
no gene flow
no genetic drift
no mutations
no natural selection
random mating

7. plans have cell walls made of cellulose
bacteria dont always have a cell wall. (look up gram-negative and gram positive.) cell wall is made of peptidoglycan!

good luck - make friends with Wikipedia!!

1. LOL I think it is referring to coral reef. Coral and jellyfish are both in the phylum Cnidaria.
2. Dont know all the functions. I do know spongy bone is named so b/c it looks like a sponge. Bone marrow is interspersed in spongy bone. Bone marrow is where red blood cells are made.
3. pituitary glad only makes and secretes hormones, meaning it has endocrine functions ( hormones into blood stream = endocrine). exocrine glands dump enzymes into ducts ( see the difference?). i believe tropic hormones are hormones that affect other endocrine glands, not sure though.
4. No idea lol.
5. again, nothing.
6. im sure someone can explain this better than I can. I just know the assumptions, not why they are so 😀.
7. yes, fungi do have cell walls. not sure about the first part of your question... do you mean the differences b/w the cell walls of bacterias and plants?
8. nothing

hope that helps some

1) yes it is a type of jellyfish or hydra and its main stage is polyp..
2) Spongy bone are less dense than compact bone and it is the site of adipose or fat storage, yellow bone marrow and also red bone marrow which gives rise to RBC..compact bone are comprised of haversian systems with nerves and canals running through them.
3) I think it doesnt have exocrine because there are no ducts...it stores hormones from the hypothalmus...tropic hormones basically stimulate other glands to secrete hormones while direct hormones just directly stimulate a certain function...
4) Batesian and mulleurian is a type of mimicry...mulleurian is when two unharmful species mimic each other while batesian is one unharmful mimics the harmful one...
5) Neurlation i believe is the process of embryonic development when the nerve cord and noto chord develope...
6) When you have isolation you can have allopatric speciation which will bring about a new species, hardy weinberg determines allele frequency equillibrium so a population of species doesnt want to be isolated or their allele frequencies will change...
7) The cell walls of bacteria are made of pepdidoglycan, fungi also have cell walls I believe but it is made of chitin...
8) I am assuming you mean degeneracy and redundancy of the amino acid codons...if so it just means that the codons can code for more than one aa, and multiple variations can code for the same aa.

1. Is coral a type of Jellyfish and if so what stage does it represent?
Coral is in the same family as jellyfish, which is cnidocytes or coelentrates. It is immobile, so it must be polyp phase
2. What are the functions of spogy bone and compact bone and in which one does RED blood cell are made and which one holds fat?
Functions is very broad, so I am not going to elaborate on them. Red marrow and yellow marrow are both formed in long bones that consist of spongy tissue and compact bone on the outside. If I was asked to choose between the two then I would select spongy...just cuz
3. Why doesnt the pituitary have exocrine and endocrine also? what is a tropic hormone?
Pituitary does not have neurons extending from it to have any exocrine functions...besides its doing too much work by releasing all those hormones all the time. Tropic hormone is any hormone that acts on target tissue and causes it to release other hormones.
4. wtf is batesian and mullocrin?
Batesian mimicry is when an organism with no special defense mimics other organism that looks the same, but has some sort of special defense to ward off predators.
Mullerian mimicry is when two harmful organisms look alike, for example black and yellow stripes of wasps...so that predators know to ignore anything with yellow and black stripes.
5. can someone explain neurlation?
Can't explain this in two sentence...very broad. I will say that it comes after gastrulation and it promotes the development of nervous system in cranial to caudal direction.
6. Hardyweinberg why is one creteria "no isoloation" and what does that mean?
I believe: Isolated populations are small and so genetic drift could be in effect changing the allele frequency.
7. Both bacteria and plants have cell walls, how do they differ? does a fungi have cell walls?
They all have cellwalls made of different materials.
Bacteria: peptidoglycan
Plants: cellulose
Fungi: Chitin
8 what is difference between degenerate and redundancy?
I thought they were both the same things.

Answers are in color.

 

[theedaddy77]

you guys were soo helpful it is amazing😀.
1. I got everything exepct the neurlation one.
2 so the pancreas is tropic hormone cause it can stimulate or not stimulate the liver to release glucagon. And the Antitory pitutority is also troipic cause it can activate the adrenul gland? aLso if something has a exocrine function that also means its tropic gland right? And an endocrine means actually i still dont understand what that means 🙁

 

[happyasaclam88]

tropic hormones are still endocrine, since endocrine just means hormones being released into the blood. exocrine activity means releasing things into ducts - ex the gall bladder releasing bile.
good luck!

to clarify
red marrow where blood cells are made, also where monocytes are located and also the cite of T lymphocyte development and platelets
yellow marrow = where fat or adipose is at

so how does spongy bone or compact bone relate to all this? or does anyone want to add something i missed?

For .Hardyweinberg equilibrum does it require large populations or small populations. I thought it was large but wiki says something else......

I know all blood cells are made in the red marrow but I thought monocytes develop in the tissue, and T cells develop in the thymus. can someone clarify?

spongy and compact relate to this because the marrow is in the spongy bone.

HW requires large pop.

i know as soon as i saw a thread with a bio question id see osimsDDS respond with a great answer... hahah, dude youll get a 30 in bio for sure, you know your stuff

 

[NuckingFutz]

I'm confused, can someone explain #6?

I thought that you WANTED isolation so that there isn't any gene flow occurring from nearby populations?

I remember this being a destroyer bio question and found it confusing 😱

haha thanks danuch but 2 ppl beat me to it...

Yea i believe that you want isolation so there wont be gene flow, but it could mean no isolation of individuals or yes isolation of the population from other populations...but anyways i think the correct assumption for hardy weinberg is that you want the population to be isolated so NO gene flow.

Now for population size if you have a small population size it will effect genetic drift which is the probability of changing the allele frequencies in a population...so you DO want a large population so genetic drift wont be a factor...

Basically if you remember that hardy weinberg wants the allele frequencies to NOT change then you can predict every outcome for any question...no natural selection which does change allele freq., no mututions, yes isolation from other populations, yes big population to minimize genetic drift, and mating is random to minimize again genetic drift...

hope that helps

AND i just found out wut neurulation means....its when the ectoderm forms into the neural tube which then form the neural crest. cells from the neural crest then migrate and form new tissues of the ectoderm...

 

[theedaddy77]

thanks for the responses guys does anyone know the answer for the bone question though?

 

[mcdds75]

tropic hormones= to "go to", 5 ant. pituitary cell types with products(ACTH, TSH etc..) hormones are secreted from endocrine glands into the bloodstream, and travel to tissues where they bind to hormone receptors on target cells to give an effect!

trophic hormones= to "nourish" they make something grow or proliferate to be exact!

On #1, both coral and jellyfish are in the phylum Cnidaria; however they are not in the same family: Anthozoa=Corals and Scyphozoa=Jellyfish. So, I would say that coral is not a type of jellyfish considering that they are not in the same family. Corals are always in the polyp stage because they reproduce asexually.

 

[excusezmoi]

here's what I think for
1. Cnidaria
a. hydrozoa - example is hydra which has both polyp and medusa stage
b. scyphozoa- ex. jellyfish comes in 2 stages, first is polyp then medusa stage, which is the main stage
c. anthozoa- flower-like ex. corals, polyp stage only.
