lol Thankyou madharris and Aysce, I was only gone from this thread for like two hours and it's flooding

Identify data sources, choose equipment or resources, gather process and analyse information from secondary sources to describe the processes used in the clonining of an aniaml and analyse the methodology to identify ways in which scientists could verify that the animal produced was a clone

can i just use dolly the sheep? if so, whats the difference between the first part of this dot point and the one in blue print of life?

Also, wth is the second part about?"????

 

[ZombieApocalypse]

ur supposed to observe and identify the different parts of the kidney, both external and internal, and also relate the function of the kidney with its structure.

External? what was an external feature that related to a particular function

Internal:
Cortex- responsible for filtration. More firm? maintains structure
Medulla- high surface area. Extremely pink. Reabsorption occurs here.
Pelvis- white part. Used for collecting of waste and leads to bladder

is there anything i'm forgetting?

Yeah, you can use dolly the sheep as an example. THe general description of the whole organism process is:
The nucleus of a reproductive cell (or egg) is removed and replaced with the nucleus of the organism that is to be cloned.
This cell is then allowed to grow in a laboratory until it is large enough to be implanted into a surrogate mother. The clone then grows as a normally conceived organism would.
(This description is not relevant for whole plant cloning)

The identifying if an animal was a clone part is by using DNA fingerprinting:

DNA fingerprinting is the use of the non-coding regions (introns) of DNA to uniquely identify an individual
The non-coding sections of the DNA consists of lengths of base sequences that are often repeated many times
Organisms gains half of their non-coding sequences from their mother and half from their father, to give a unique pattern of non-coding DNA sequences
A DNA marker is an easily recognizable flag that identifies the presence of a useful or desirable gene. Scientists use about 10 marks to create a DNA profile or fingerprint of an individual
So by comparing it to the original organism, and seeing that it has the same introns, we can see that it is a clone

there's not really any differences between the BOL and genetics dot point

is this an optional?

OK, I hope your not refferring to the genetics option if not I think this dotpoint is needed to be answered:
-DOTPOINT: process information from secondary sources to describe a methodology used in cloning:
-so the methdology is called "somatic cell nuclear transfer" which was used to clone dolly
-the process included taking a donor cell (mammary cell from the udder of a finn-dorsett sheep) and removing its nucleus and obtaining an egg cell from another donor and removing its nucleus aswell
-then the nuclus from the mammary cell is implanted into the egg cell via a micropippete
-the egg is then stimulated via electricity to initiate cell division
-the newly formed embryo is implanted into a surrogate mother
-a clone is born genetically identical to that of the donor whose mammary cell was used.

Yeah it's the genetics option topic again

However the first part is part of BOL

 

[Aysce]

wtf, is this a dot point?

LOL i shat myself xD

 

[RishBonjour]

Last question before I start revising all four topics (sleeping at 2)

Assess the social and political influences on the development of evolution (have a feeling it might pop up)

If it's a question, how many marks is it?

and do you mean the theory of evolution

 

[TheOptimist]

With transgenics(recombinant DNA) in BOL, here's a nice analogy you could use:
CUT: Restriction enzymes are used to cut specific lengths of DNA/desired gene
COPY: The gene is inserted into a plasmiid(non-chromosonal DNA) of a Bacterial cell--->Bacteria replicates---> genes extracted
PASTE: Gene(with initiator sequnence to "switch on" gene)is then inserted into the egg cell of another species via Biolistics/electroporation/micropippete/transduction ----> after the egg cell is fertilised new transgenic organism created.

"analyse information from secondary soruces on the historical development of the theories o evolution..." its a dot point on BOL.

atleast 5 marks.

Ok so this is linked to Darwins theory of evolution, some things you could talk about: social darwinism/Wilberforce Huxley debate/creationism vs evolution/redefiintion with mendialian gentitics; neo darwinism etc, you should also talk about social implications with religion etc --->used natural selection as justification for worng doings

Does anyone know what we're meant to include when we 'evaluate the effectiveness' for this outcome?
Evaluate the effectiveness of quarantine in preventing the spread of plant and animal disease into Australia or across regions of Australia

Question: with copy, could it also be PCR?

 

[madharris]

-Christianity was a dominant force during darwin's time, creationism was widely accepted as a scientific concept (trololol)
-Darwin knew the impact that his knowledge would have on the world, so he didn't publish his findings for about 25 years

-His theory caused a great uproar in the society at the time, great debates were fought out over evolutionists and creationists
-The idea that humans are descended from apes caused outrage as people thought they were 'God's special creatures'
-Darwin has been blamed for atheism, communism and even WWII

Yes

I would do it like this:
Outline what is quarantine
Do your intestate example of quarantine around australia
Do your international example of quarantine in australia
Advantages
Disadvantages/limitations/occurences where quarantine hasn't worked
Overall judgement
