This process is called diffusion
hope that helps
On the periodic table, you will see that they are grouped into different groups. Well, on the right, you have the groups, obviously. You are supposed to match the elements to the group that it is in.
(If you don't know the groups, you can find one online under images.)
Hope this helps! Please give brainliest answer!
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
Wait what????? How many light years!?
True statement. Sperm are continuously produced by males, while a female is born with a full supply of eggs.
Characteristics of egg cells and sperm cells.
*Egg cells are usually formed in a female before birth while sperm cells form during puberty.
*Egg cells are produced in the ovary of a female human being while sperm cells are produced in the testicles of a male human being.
*Egg cells are included in the largest cells in a female body while sperm cells are the smallest cells in the male body.
*Only a single egg cell is produced during ones menstruation cycle while millions of sperm cells are released during a single ejaculation.
*Egg cells formed before birth and are active only until female menopause while sperm cells production started during puberty until death of the male body.
