Eh . . . don't have my book with me so I'll see what I remember.

Neolithic farmers lived in rectangular huts which were made from wattle and daub, and straw. Walls were made out of wattle and daub and the roof thatched out of straw. Wattle and daub was saplings or branches woven together to make a frame, before being covered with mud and clay to keep out draughts.

Next Q: Name the parts of the skeleton & the joint;

Is anyone going to answer the question or will I answer my own?

Bones are humorous (sp) and femur. We haven't covered muscles and joints yet!

WanderingSoul

Seriously?! We've been finished since October!

By the way: D is a ligament and C is synovial fluid.

What's your question?

Jackobyte

Retarded teacher who doesn't know/cannot expand on anything the book says

What is latent heat?

WanderingSoul

Latent heat is heat used in the changing of state in a substance. In a graph, it can be seen in the form of a plateau.

Have you done this yet?
Next Question; Name the parts of the eye;

Jackobyte

A=Vitreous Humour
B=Lens
C=cornea
D=pupil
E=iris
F=Sclera or Choroid layer (I can't tell from diagram but had to check book anyway)
G=retina


What is the function of the ciliary muscle in the eye?

WanderingSoul

Well done! That was a hard one.

To hold and bend the lens to correctly focus light onto the retina.

Next Question; What is / Define

1) Acceleration
2) Acid
3) Asexual Reproduction

Jackobyte

Acceleration=the change in velocity of a moving object
Acid=I actually don't know the definition! Would "a substance with a ph level or 1-7" count.
Asexual reproduction=the reproduction of an organism which only requires a single parent. It usually involves the use of "runner plants" to produce a new identical individual.

Can you correct my above questions, I know they aren't fully right.

What is the difference between xylem and phloem tissue in a plant?

WanderingSoul

Yep, it would. I don't think it has a particular definition which is why I said "What is".

I'll check the answers against my notes in a moment, okay?

Xylem tissue transports water around the plant.
Phloem tissue transports foods around the plant.

Bold = How i remember the difference.

WanderingSoul

Sorry.

Next Question; What is / Explain / Define;

1) Centre of Gravity
2) Alloy
3) Antagonistic Muscles

Jackobyte

1. The point in through which an object appears to move
2. This is a mixture of two metals, e.g. tin.
3. Don't have a clue

Damn, my answers seem so inadequate! :eek:

5 steps of water treatment?

The acceleration definition is correct, although I said in my notes it is the rate of change in an objects speed or velocity.

Yes, I would say for the acid definition you would be right in saying a substance with a pH of less than 7.

Your definition of asexual reproduction is essentially correct; maybe mention that no gametes are required and fertilisation does not occur.

3) Antagonistic Muscles

They are when a pair of muscles pull in opposite directions such as biceps and triceps!! I think anyways!

Your answers are fine!

1. screening,
2. settling,
3. filtration,
4. chlorination,
5. floridation

1) Conduction
2) Atomic Number
3) Digestion

Conduction is the transfer of heat through a solid material
An atomic number is the number of protons an atom has in its nucleus
Digestion is when food is broken down so it can be absorbed into the body ( not sure)

WanderingSoul

And your question?

Conduction; maybe add in about particles (it passes from particle to particle)? You're right though!

Atomic Number; yep, you're right!

Digestion; The breakdown of large insoluble food molecules into smaller soluble molecule through either chemical (enzymes) or physical (teeth) means.

I'll ask a q if it's ok. My science teacher gave us past pre papers for homework and one that came up multiple time is:

We were probably writing it at the same time.

Jackobyte

Convection-The transfer of heat by moving air particles.
A Base-substance with ph above 7
Enzyme-a biochemical catalyst

My question;Why is helium used in airships instead of hydrogen?

WanderingSoul

"Why is helium used in airships instead of hydrogen?"

It is less dense?

Next Q; What is / Define / Explain;

Density
Chemical Reaction
Fertilisation

WanderingSoul

Oh yeah, since a lot of these questions are science, what level is everyone doing (higher/ordinary) ?

Hydrogen is less dense than helium, not the other way around. It's just not used anymore in airships as it can easily combust.
