Could also mention the frontal lobe for thoughts, learning, memory and speech. And also the parietal lobe which processes speech

Discuss the use and limitations of models when illustrating biological concepts. (3)

Nice, could also mention that a change in the concentration of water in cells could interfere with the functioning of enzymes and metabolism would be disrupted Might be too much for 3, but it's another reason

Explain why the concentration of water in cells should be maintained within a narrow range for optimal function. (3)

Describe two processes that ensure genetic diversity in sexually reproducing natural populations. (2) OR The two research teams of Watson and Crick and Franklin and Wilkins were both aiming to discover the structure of DNA. Assess the contributions of both research teams to the discovery of...

I think so, can't hurt. I've seen a few questions that you may need to know, just keep it basic anyway Edit: What BlueGas said ahaha

Humans detect sound at a frequency range from 20- 20,000 Hz, this allows humans to effectively communicate, either through speech, or to issue warnings. Due to differences in environment, and the competition for resources, bats can perceive sound frequencies from 100,000 - 120,000 Hz. Because...

Homeostasis is the maintenance of a constant internal environment, however, enantiostasis is where an organism can maintain maintain its normal functioning despite the outside environment changing. It can do this whilst not maintaining homeostasis - e.g. the salt levels in an organism can...

Yeah it's shit. But if I had to choose, I'd go with: - Erasmus Darwin (1731-1802) — suggested that the strongest and most active individuals would survive and continue a species. - Jean-Baptiste Lamarck (1744-1829) — suggested that features acquired during the life of an organism could be...

Each gene inside a cell can be 'switched off' and 'switched on' by a number of conditions both within the cell and outside the cell. A gene is expressed when it is ‘switched on’ and the DNA encoded within this gene is converted into polypeptides. The body’s cells are always being replaced, thus...

It's pretty much the same thing that they both independently discovered I think? Isn't the only difference how they came about it? As in sea urchins and grasshopper testes? Not sure either

So prophase 1?

Crossing over occurs during the process of meiosis. It is the process in which homologous chromosomes exchange genes and so the resulting combinations of alleles on chromatids differ from those originally on the parent chromosome. This affects the inheritance of genes as it produces many...

A prion is a protein altered from its previous structure, and can cause other proteins to alter, creating more prions in a chain-like reaction. Prions are responsible for diseases such as mad-cow disease. These are observable under a microscope. A virus however, consists of DNA or RNA enclosed...

3/3. Not sure about the statement? Could be added, but I think the concluding statement "therefore not all mutations are harmful" should be enough considering what you discussed beforehand and how that relates to the definitive statement, should be good. Not sure though haha

Candidiasis is a disease caused by an imbalance in the numbers of the fungus, ‘Candida albicans’. The fungus is usually kept in check from competition from other microbes such as bacteria living in the same area The taking of certain medications, such as wide-spectrum antibiotics (which can...

Increased water salinity would upset the water balance in the Murray Cod because freshwater fish normally have a higher salt concentration than the environment and due to their osmoregulative nature, they choose to tolerate these changes rather then adapt to them, and this results in the...

How about a Blueprint question? How does the concept of punctuated equilibrium in evolution differ from the gradual process proposed by Darwin? (4)

Passive transport happens after the initial filtration in the Bowman's capsule as water returns via the interstitial fluid from the tubule to the capillary And then active happens with the ions in the blood, depending on their concentration they can be transported to cells in the nephron tubule...
