The answer is heat. Heat from the Sun causes water to evaporate from the surface of lakes and oceans. This turns the liquid water into water vapor in the atmosphere.

What is the Reynolds number for blood leaving the heart through the aorta if the diameter of the aorta is 2.15 cm and the blood
defon

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

Explain Mendel’s laws in genetic terms, that is, in terms of chromosomes, genes, and alleles.
Paladinen [302]

Answer:

Law of segregation is when two genes control the alleles and those two genes go to two different chromosomes. Law of independent assortment is when two genes control the alleles and are inherited independently.

Mrrafil [7]

This is the complete question

Scientists once believed that modern-day reptiles were the only living descendants of dinosaurs, which were reptiles. Accumulating fossil evidence has now suggested that the most recent dinosaurs gave rise to birds, making birds one of the closest living relatives of dinosaurs.

What statement provides the strongest evidence to support the claim that birds evolved from dinosaurs?

A. A fossilized rib cage of the semi-aquatic dinosaur Spinosaurus shows that it had lungs.

B. Fossils of the beaked dinosaur Ankylosaurus show that it had modified scales that produced hard, bony plates.

(C. Fossils of the winged dinosaur Archaeopteryx show that it had modified scales that produced feathers.) c is the right answer

D. A fossilized nest of the herbivorous dinosaur Brachiosaurus shows that it laid external eggs.

The correct answer is option C, that is, fossils of the winged dinosaur Archaeopteryx show that it had modified scales that produced feathers.  

<h3>What is Archaeopteryx?</h3>

Archaeopteryx is considered an intermediate fossil between the dinosaurs and modern birds.

With its amalgamation of reptilian and avian characteristics, it was long considered as the earliest known bird. It was found in 1860 in Germany, it is sometimes also called Urvogel, that is, the German term for a first bird or original bird.  

Thus, The correct answer is option C.
