Answer:
Cartilage rings of trachea have protective role
Explanation:
Trachea is a tube, part of the respiratory system, which allows the passage of the air: from larynx to lungs (primary bronchi). It is enveloped with cartilage rings that prevent collapse of the trachea when there is no air. The cartilage "rings" are C-shaped, except one full ring-shaped - the cricoid cartilage which attaches trachea to the larynx.
Answer:
18
Explanation:
8CO₂ + 18H₂O + energy ⟶ 3C₆H₁₂O₆ + O₂
C is balanced
.
We have 54 O on the left-hand side, but only 20 O on the right-hand side.
We need 34 more O atoms on the right, for a total of 36. Put an 18 in front of O₂.
18CO₂ + 18H₂O + energy ⟶ 3C₆H₁₂O₆ + 18O₂

In the solar system there is a lot of distance between mars and Jupiter. the main asteroid belt is in this area. what is the reason a planet did not form between mars and Jupiter
a. Planets can only form close to the sun or far away from the sun. This area is a region where planets cannot form
b. This area gets a lot of stellar wind from the sun. planets cannot form in areas that get a lot of stellar wind
c. Mars has two very fast moving moons, these moons prevented a planet from forming in the area.
d. Jupiter's gravity affect this area so much that no planet could form there.
A punnett square shows all possible results o a cross between two individuals because it shows the parent genotypes and you multiply them to get the results of an individual
example
parent A: Rr = R, r
parent B: rr = r
r
R Rr
r rr
