An expansion in venous tone will increment heart yield and increment mean blood vessel weight. All blood vessel and venous vessels under basal conditions display some level of smooth muscle compression that decides the breadth, and thus tone, of the vessel.
Answer:
b. laminar flow
the reynold number is 1329.26
Explanation:
Re = (V x D x ρ)/ η
where,
V = mean velocity = 15.9 cm/s = 0.159m/s
D = vessel diameter = 2.15cm = 0.0215m
ρ = blood density = 1050 kg/m3 = 0.00105 kg/cm3
η = dynamic viscousity= 2.70 × 10-3 Pa·s = 2.70 × 10-3 kg/m-s
applying the formular to calculate for reynolds number, Re =
Re = (V x D x ρ)/ η
=(0.159 x 0.0215 x 1050) / 2.70 × 10-3
=3.589/0.0027 = 1329.26
the Reynolds number for the blood leaving the heart through the aorta if the diameter of the aorta is 2.15 cm and the blood has a dynamic viscosity of 2.70 × 10-3 Pa·s, a density of 1050 kg/m3, and travels at a mean fluid velocity of 15.9 cm/s is 1329.26
which flow through the aorta in a Laminar flow
Note that
a) turbulen= Re >4000
b) laminar= Re <2300
c) transitioning between laminar and turbulen= Re between 2100 and 4000
Answer:
The percentage of the non-singing trait in female birds in Generations 4 and 5 if this pattern continues will be 80 and 94
Explanation:
The percentage of the singing trait in female birds in Generations an 5 if, the pattern continues, is 26 and 18 respectivelyFor the non-singing females, we can see that 8 was added to the first term to get the second term. 10 was added to the second to get the third
For the 4th term, 12 will be added to the third term;
T4 = 68 + 12
T4 = 80
For the 5th term, 14 will be added to the fourth term;
T5 = 80 + 14
T5 = 94
Hence the percentage of the non-singing trait in female birds in Generations 4 and 5 if this pattern continues will be 80 and 94
I think the answer is c may not be fully right
Cross: AA × aa
F1 Progeny: Aa , Aa, Aa, Aa
Now, F1 Cross: Aa × aa
Progeny = Aa, Aa, aa, aa
Phenotypic ratio would be: (Agouti to smooth-haired) = (1:1)
Hope this helps!
