Biology Short Questions

Leeg17

Would appreciate it so much if someone could post the answers they wrote in bio, there were a few tricky parts imo, here's the paper : http://www.examinations.ie/archive/exampapers/2009/LC025ALP000EV.pdf
Just to compare with what I wrote and ease my nerves a lil
Cheers, :cool:.

The fck was the correct term for the 8=======8<--- this bit
On the bone question?

Fringe

A was epiphysis.
B - Diaphysis
C - Spongy Bone
D- Compact Bone

So glad I crammed that just before.

Claypigeon

Diaphysis, that's the one -.-

I said Osteoblast

Leeg17

Are C/D not Red bone marrow / Periosteum... they were so hard to make out... :mad:

Worst diagrams I've ever seen in a biology exam, really bad.
I had red marrow and compact bone.

arthistory

Q1
Hydrogen:Carbon

polysaccharides consist of many monosaccharides joined together

starch

cell wall

benedict's solution

heat but don't boil.

Q2 Radicle

Hydotropism

Phototropism

Get more light which is needed for photosynthesis so they can make more food

Ethene...not sure about that one.???

rooting powder used to make roots grow on shoots faster than would happen in nature
IAA is used to stimulate formation of callus in micro propagation

Q3 Predation is the catching, killing and eating of prey

Fox
rabbit
funtional role in habitat
photosynthesis
refers to soil factors
pH of soil

Q4 A epephysis
B diaphysis
C Spongy bone
D Compact bone

between the 24slightly movable vertebrae
shock absorbers
yellow bone marrow, can be converted to red bone marrow to make bllod components if needed....is that right??
red, make blood components

Q5 Anaphase
double stranded chromosomes have been split into single strands
a spindle fibre
b chromosome

asexual reproduction
growth
meristematic tissue

Q6 artificial manipulation or alteration of genes

Isolation
Cutting with restricion enzymes
Transformation

bacteria makes insulin
goat make protein to treat cystic fibrosis
weed killer resistant crops.

Hope this helps and I hope they're right!!!:)
