Biology

Biology - The science of life and of living organisms, including their structure, function, growth, origin, evolution, and distribution. It includes botany and zoology and all their subdivisions.


Well anyway, I just want to see how smart you people are :D.
I will take questions from my Biology book and see if you can answer them.

For now, here is the first question.


What is the name of the only mammal that can fly?

[Bjwbell]

Bat.

[kovan]

Matthew
need your homework done? :)

Bjwbell = correct.

kovan: nope, I'm just checkin' all your Biological skills :rolleyes:. We are in the Cell Cycle with Mitosis and it's phases and all the other boring crap.

..just wanted to see how much people know.

More to come...:rolleyes:.

that's starting to bring back some distant memories

oh god... I hate biology....

right now we are doing this dumb lab, we have to look through a light microscope at a cell, and count how many are in prophase, metaphase, anaphase, etc..


it's so boring....... :o

[kovan]

i dont like mitosis
osmosis was always my favourite
still use it in some of my talking sometimes
:)

[Skeen]

I was quite into biology at school, we did a lot with vegetation you know.

Ah yes, Biology....Mary Ellen Engleman right in front with the tight skirts and the semi-see thru blouse.....

I failed Biology.

[kovan]

personally biology facinated me
i still love biology to this day
and actually am thinking of taking a biology course for the hell of it

I hate Biology :rolleyes:.
I'm getting D's on all my quizzes, last marking period, I got a B! :(
This marking period, not doing to well, think I'm dropping down to a C. Only thing that keeps me up is that I do my homework.

Next question...


Which bird flaps it's wing so fast, it stays hoverring in place?

[Edited by Matthew Gates on 12-20-2000 at 03:14 PM]

humping bird... errrr. I mean humming bird... :rolleyes:

Too easy :rolleyes:.

Another question or two...

What is the equation for Photosynthesis?
What is the equation for Glycolysis?

[HarryW]

I thought this was about Biology? That looks a lot like Chemistry to me. Never liked Biology, too much waffling and not enough straight answers.

Equation for Photosynthesis:

Sunlight and Green Stuff

Hehe, guess I moved to the Chemistry section :rolleyes:.

Photosynthesis

CO² + 6H²O (light)---> C6 H12 O6 + 6O²
carbon dioxide + water (light)---> glucose + oxygen

Glycolysis

C6 H12 O6 + 6O² (yields) ---> CO² + 6H²O
glucose + oxygen (yields) ---> carbon dioxide + water


Purdy simple, aye? :rolleyes:

To DNA...

What does
A
T
G
C
U
stand for?

[Benjamin]

those are the thingy's... ohhh crap... um..... amino acids?
I think thats it.... well, those are the things that make them up...


if I could find my bio book, I get answer what they stood for..

[HarryW]

I don't doubt it Dennis, since that's where Matt got them from in the first place :rolleyes:

Okay, question for you: How many flavours of quark are there, and what are they, not including antiquarks?

See if that's in your physics book ;)

physics aint till 11th or 12th grade.

Dennis

.....lol....on the humping bird thing.

All

We covered human evolution in Biology, and this was at a Catholic school. I hear a lot of US schools don't allow this, ah yes "America home of the blinkered mind set".

Question

What does
A
T
G
C
U
stand for?

Answer
[b]A = Adenine
T = Thymine
G = Guanine
C = Cytosine
U = Uracil (RNA)

Surprised no one knew these :rolleyes:.

[parksie]

Okay, question for you: How many flavours of quark are there, and what are they, not including antiquarks?

Red, green, blue, strange, charmed (I think that's it, anyway!)

[b]Question

How many chromosomes are in the human body?
How many chromosomes are in the cell when it divides into 2 (how many are in each? Needed: First question is needed to answer the second question)?

[parksie]

1: 46
2: 23

Dammit parksie! That was suppose to be a challenging question! :mad: (sarcastic mad)

Oh well, I guess it's just there in smart people's human brains :rolleyes:.

[parksie]

Oops... *giggle*

Too tired to feign ignorance...but it won't be too long before i don't need to.

Question

What is Mitosis?
Name the four phases of Mitosis? (It's actually five: 1st phase is Interphase; name the other four.)

[parksie]

Prophase, Metaphase, Anaphase, Telophase :D

Our biology teacher had an interesting method of remembering that one... ;)

HUMANS

Question

When did the first homo sapiens appear on Earth?
Our early species were called what?
When did the first homo erectus/habilis appear on Earth?
What are humans most related to? (What animal?)
Where was the oldest human settlement discovered? (starts with a K)


These are a bit harder parksie :D.


(Note to myself: Chapter 34; P. 756)

Rama something or other. But research in oz koori burial sites is pushing this back.

Answers

When did the first homo sapiens appear on Earth?
500,000 years ago.
Our early species were called what?
Neanderthals.
When did the first homo erectus/habilis appear on Earth?
1 million years ago (spread throughout Africa, Europe, and Asia).
What are humans most related to? (What animal?)
Monkey.
Where was the oldest human settlement discovered? (starts with a K)
In a valley in Kenya called Olduvai Gorge.

[Arbiter]

Phew,

Well out of my league in this thread. I'm going for a beer.

And no, I don't want to know about the fermentation process.

DerFarm,

Like your formula for photosynthesis...

[HarryW]

Well since I'm not keen on Biology, here's the answer to my physics question:

There are 6 flavours, which are: up, down, top, bottom, strange, charmed

Well, I managed to remember strange and charmed :)

[smh]

I took Biology and Chemistry with the same teacher. Here's a breif description of him:

roughly 65 years old
enormous beer-belly
dressed in 70's style clothes
unbuttoned his shirt almost to his belly button (I think he did this so that we could see his cleavage...)
wore way too many, way to big gold pieces of jewelry (wore a hugh gold medalion around his neck)
his hair was permed in very tight black curls - yuck!


Well, if you didn't think that description was that bad...remember, this was all taking place about 5 years ago.

He also would lean across his desk like he was posing for a photograph or the girls in the class were checking him out or something...

Well, I have to go and expel my dinner after that memory....excuse me..........(running to the restroom)....

[alex_read]

I took an A-level Biology exam about 2 years ago (won't say what grade I ended up with ;))

I've been away for few weeks from the site, so have only just seen this post, come on then, got any more questions or is that your lot?

[Skeen]

OK, can anyone remember (no texts books on laps either matthew), how to de-green a leaf and measure starch content. Niether can I, and it dosn't mater because I've never ben asked to do it in the past 10 years, and I can't see it being a particular stumbling block in the future. If this has already been on, sorry, I've just got back from holiday. Happy new year to y'all, 'ave a good 'un!

Skeen

[alex_read]

Soaking the leaf in Iodine solution comes to mind for the degreening part, and I think you then boil it in water for a while.

These are just from the top of my head though, can't remember at the moment for how long this is for, and how you measure it. :)

[HarryW]

If I remember right (this is from about 5 years ago), you submerge the leaf in boiling water for a few seconds to kill it (thus stopping any conversion from sugar<->starch) and then dip it in ethanol... can't remember why though, but the leaf goes kinda yellow when you put it in the ethanol... maybe it does something to the clorophyll?

[Skeen]

Nice1, thats a hell of a lot better than what I came up with. Gold Star

Tut tut, boys, very sloppy.
You cannot answer q. 1 with any certainty since new remains are being found and the dating is very approximate anyway.
q.2 cannot be certainly answered since it is not precise enough. The q should be phrased What was the direct ancestor of Homo Sapiens - but it is definitely NOT Homo Neandertalis - there is no shared DNA.
q.3 currently thought to be at least 2 million years
q.4 Chimpanzee is NOT a monkey - it is a primate and there are arguments for and against which primate we are most related to, however it is unlikely to be the Lemur!
q.5 OK, but the q should include a caveat, such as, Where is the oldest, currently known human settlement?

It is all about analysis...

Cheers,

P.

Guess I got lazy with my answers.

Never mind eh, nearly friday.
