Cartilaginous joint, i'm pretty sure.
Answer:
TRue
Explanation:
The number of eggs per nest is called a clutch and it has been seen to vary among species. Turtles that live on water can lay more than one clutch in a nesting season. In most cases, the turtles do lay over 110 eggs per nest, two to eight nests a season.
When these eggs numbering over a hundred are laid, and only a small fraction of the offspring from those eggs make it to the ocean, with a few of these ending up with offspring of their own, then overpopulation has set in.

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
A hypothesis is something u assume before the research has been made and a theory is a explanation already supported by evidence/data.
