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:
Sunflowers can take up high concentration of radioactive isotopes and sequester them in stems and leaves hence, they have been employed to clean up contaminated sites following nuclear disasters.
Explanation:
Answer:
The regularity of DNA's overall structure.
Explanation:
DNA is the genetic material of almost all the living organisms but RNA may also acts as the genetic material in some viruses only. The mutation in DNA may cause characteristic disease in individual.
The nucleotide excision repair mechanism excise the wrong nucletide and replace with the correct nucleotide. The overall DNA structure like its nucleotide sequence, the size and angles between the DNA base pair, its methylation helps in recognizing different DNA type.
Thus, the correct answer is the regularity of DNA's overall structure.
Answer:
Mitochondria
Explanation:
If ever in doubt, just remember: Mitochondria is the powerhouse of the cell
