Narrowing of airways but which ones
Bronchi bribhcioeldm
To do vital capacity what instructions ( don’t mess this up)
Breathe in as much as you can (which causes drop) followed by strongest exhalation ( which is the rise reversed!)
For fraud mitosis meiosis questions
Just check where diploid to haploid and that is meiosis, if not gamete to gamete is MITOSIS STILL never been taught but I guess it happens
What is chi squared test used for ?
No time to think , for significantly tests what should you jus do
You know in maths if it’s a above, you accept, so here reject
In maths if itdbe,ow, reject , so here you accept
Again when doing bio questions what should you do
State everything you know waffle, if asking for structure, say water is released and why itnhad to be flipped even though they aren’t asking why
Chitin rings!
For support snd stop it from collapsing
When they mention changes in temperature what do you have to do aswell?
Mention high temoertaure and low temoertaure too and what happens for both
And here you mention went straight away to denaturing when actually a good amount of q was why doing it wa goof
Remember in ensymes increase temp is good because more likely enzyme substrate compels formed, but too much causes breaking id bonds in tertiary and so change to 3d shape, change to active site, can no longer fit or cause it to change shape to fit, so cantcalayse
But go too les and rate of reavtion just decreases, reversible but decreases
And lrocessof it happening, first they collide successfully , then enzyme substrate made, revstjon happend enzyme product made then it splits
Fraud 6 markers askmfor dimialrlites and difference what should you do
All similarities
All differences , use infrimstjokn from diagrams
Descfirbe sequences after that and GIVE RANDOM REASONS TO WHY ITS NOT EFFECTIVE OR IS even though they didn’t ask
Or give reasons to why you itsthere
Only answer to differecnes between cinfical?
Less resolution then electron mcircooe ,
But main one is ability to see layers and at different depths of the sample
Why is something at prophase 1
Remember here the chromosomes have condensed so visible, so minimum is prophase
Then the membrwne hasn’t disintegrated but no nucleolus ANother tell
But what you thought - the fact that they aren’t arranged in the middle, or at poles or as separate cells suggests it has ti be prophase
Okay remember dknt descibre bivslsnrtd for metaphase, whole point is that it’s random assortment
But jf you mention it after fully describing other first
You do need to go over the directions , how to do for celery
Cut transversely
Then add stain and view
What can you say about the walls of cerophytes vs hydrophytes!
Xeroyohytes have thicker kigninfied walls? For xylem
And hdrlhote thin but that makes sense because most of plant just supoorted by water so structure don’t have ti be that string
I think they mean more lignin less water loss but idk
Xylem and blöken similarity
Both msde up walls joined end to end and have lack of contented
Direct fish insect to see system?
Remove operculum/ exoskeleton
Idk out the gills in water and see them separate, then use manual buccal pumping or something , microscope see them cut them idk
Differences between insect and animal trachea
Insects have many animals have one
- diameter of insect traces small anaimal huge
- insect chitin animal cartilage
- animal inomcolete insect complete
- animal Leads ti bronchi insect tracheoles
- animal has smooth muscle too aswell as elastic and also ciklated m insect don’t
Alveoli full adaptations what would you say
Not only Sa, distance, conc grsdient vent and blood supply
Not only surfactant and moist
But also ELASTIC FIBRES and how that helps
And also warm temperatures INCREASE RATE OF DIFFUSION
For suggest wuestions lit suggest something to every little thing you can think of
If it says use the data USE IT
Reasons why species decline ?
Less amount of food types less, more pesticide used here , likely to be a monoculture which mead to less variety of food
Or because no attempt o save like wildlife reserves or just management causes less habitat and thus less species
There are only three types of bidovieriety, this is not variation
Genetic species habitat
The fact someone is different colour means genetic
Compare properties and functions of globular and fibrous, what do you do?
Not asking to do actual properties but generally
So say
And for functions look for all the functions they perform in things we have studied, such as metbso,ism, enzyme catalysations, hormones, transport etc contracting and properties , structure protection elasticity
Then give examples
General properties insoluble elongated , strong , f,edible
Remmeber mucous membrane shave
Cillia goblet but also neutrophils and phagocytes and kysosozmes
What is the cofactors for amylase because they love asking this
Prosthetic group for other
