Do you need the pictures as well? Thats the official marking scheme after reading the discussions in the Biology Thread

Section 2
Name the process sodium ions move into cell
-Passive
Potassium ions move out of the cell draw the direction
I guess I drew the arrow out rather than in 🙄

How is the dwarf allelle recessive?
Since the F1 offsprings are all tall, suggesting the tall allele is dominant as it masks over the dwarf allelle.

One feature of villus and alveoli common
Both have a large network of capillaries, are one cell thick and have a large surface area.

The pyramid question
-The regular one as bush will be more in number and hawks will be less

Percentage decrease was 30%

The 4 marker was about hormone control in glucose.
When glucose levels are low, the pancreas releases glucagon which is complementary to the liver cells. It converts excess glycogen to glucose. Glucose is released in blood and increases it's level back to normal.

The other 4 marker was stages of genetic engineering.
so Plasmid is extracted from the bacterial cell and cut open, enzymes seal the gene in the plasmid. Plasmid is reinserted back into the host cell and the cell is multiplied to produce a genetically modified product.


Any other questions do type in yourselves I might update the thread in a while

the graph moves by 2 years in each bar but the question asks you to jump 4 years, so it has to be adding on 3.6 instead of 1.8 sorry
