Answer:
B) g = 0.5 h, v = 2 h^-1
Explanation:
Generation time is the time taken for a bacterial cell to divide and produce an offspring. Bacterial cells divide exponentially.
The total number of cells is given as =2n x initial number
[n = number of generations]
So if the total is 8 cells:
8=2n x 2
2n=4
n=2
That means 2 generations have arose
Generation time is given as 
where t=the time taken
if t=1hour and n=2
Generation time = 
= 0.5hour
Generation time, g =0.5h, and the rate of generation (growth rate), v is 2 per hour
Answer:
(E) left atrium.
Explanation:
Pulmonary veins are veins that carry oxygenated blood from the lungs to the heart (left atrium). These veins are part of the pulmonary circuit:
Venae cavae are a vessels (vena cava interior and superior) that carry deoxygenated blood from the body to the right atrium. From the right atrium through the tricuspid valve the blood goes into the right ventricle. Then, from the right ventricle through the pulmonary valve the blood goes into the main pulmonary artery which carries deoxygenated blood to the lungs (to recieve oxygen). Oxygenated blood from the lungs travels to the heart: two pulmonary veins from each lung to the left atrium.
