Ralstonia eutropha cells is dependent on production of Polyhydroxybutyrate in Cells that means if PHB increase the growth rate of Ralstonia eutropha will increase too.
|
PHB is a short-chain polyhydroxyalkanoate (PHA) that is naturally produced by several microorganisms it grow under limitation factor such as Gas and minerals.

1. P-53 is prevent tumor suppessor and be able to control cancer cell so tumors which lost p-53 are definitely going to be more likely to have higher mutation rates.
3. Deliverly P-53 to cells would reduce the division of cancer cells.
|
protein 53 or "Cellular tumor antigen p53 " in official name is transcription factor that control cell cycle and it also suppressor tumor and that makes P-53 significant to control cancer cell.

Salty water is being reabsorp back and it explained why urine output's salty water rate lower than normal water.
- (Salty water reabsorp back by proximal convoluted tubule(PCT) active transport).
|
- Proximal convoluted tubule reabsorp substance the most by active transport
- Loop of Henle reabsorp water the most by passive transport
- Reabsorption working with hormone ADH it help kidney reabsorp water back. When human drink alcohol, alcohol will effect to pituitary gland and control ADH hormone that's why we want to diuretic (pee) frequent.

A is correct as you can see the vessel that lead blood (high carbondyoxide gas) form right venticle to lung is too small and narrow so it cause blood with high CO2 gas to to lung lower than regular.
|
Inferior Vena Cava and Superior Vana Cava are lead blood with high CO2 from all of body to the right atrium and then right venticle to lung
lung is going to exchange gas makes blood from high CO2 to high O2 and the blood will go to left atrium then left venticle to body agian.

When we exercise hemoglobin in blood will meet carbondyoxide cause blood become toxic, the body will respond by heart rate high and heavily breath to gain more oxygen gas.
|
Cardiac output can gets high with many reason not only when we exercise or tired, but it can come from complication or congenital disease such as hypertension, heart attack or respiration and blood circulation problem ect.

C is correct because if the valve is too narrow the ability to lead blood to another place will take longer time than usual.
|
According to the passage A 55 years old man is healthy following by the BP(blood prussure), cardiac output also his heart rate all normal.

The pedigree chart shows that Queen Victoria was a carrier due to a chance mutation, her children passed the trait throughout. The pedigree also show that Heamophilia happend to only male (chromosome Y)
|
- Heamophilia is condition to ability of the blood to clot is severely reduced, causing the sufferer to bleed severely from even a small injury.
- The rare cause of Heamophilia skipping 2 generations.

choice C is correct because mice in group 1 were injected with phlorizin to control glucose in blood and renal glucose reabsorption inhibitors but mice in group 4 are normal, so that makes sense why mice in group 1 have the volume of urine than mice in group 4.
|
Phlorizin is a naturally occurring phenol glycoside and phlorizin can caused renal glycosuria and weight loss without hyperglycaemia.

A is false because the graph shows that Tidal volume is more slope and faster than Vwntilation rate.
|
TV is shows the amont of air that moves in or out of the lungs with each respiratory cycle, so if your blood acid or have too much carbondyoxide gas the lung and heart need oxygen and exchange gas means the TV rate is going to high. (It's one of the reason you breath quickly when you tired after exercise.
